Why Is My Lawnmower Battery Dying?

Suppose you are using your lawnmower smoothly, but it suddenly stops running. You have checked out all the parts, and the connections are okay. So, what is the possible reason it could be?

Plus, you have fully charged the battery, but it didn’t show any issue while charging. Simply put, you are wondering about this question, why is my lawnmower battery dying?

Here are few possible reasons your lawnmower batter may have.

Voltage Regulator is Not Functioning

If the voltage regulator is not functioning as it should be, it may cause to dying battery issue. A functional voltage regulator along with an alternator helps the battery to recharge.

Having problems with the regulator may make the battery die too quickly. Hence, you will not get enough backup to start the lawnmower smoothly.

Lawn Mower Not Working At Full Power

It is also possible you’re not cutting grass at full throttle while using your lawnmower. When you run the lawnmower, make sure you’re running it at the maximum throttle.

So, why do it? It is because it is the best way to achieve the RPMs needed to charge the battery. When the RPM rate falls, battery charging deficiency will occur. You may experience lawnmower battery death between mowings due to this issue.

A Loose Connection

It might be unnoticed to you, but there is a possibility the battery is loosely connected. A loose connection happens when the wires of the battery are not correctly connected.

A loose connection either gives no support to the battery or the battery struggles to work smoothly. It may lead to battery drainage or dying issues quickly.

In that case, you want to check out on-hand whether all connections are correctly plugged in or not.

Battery Post Corrosion

White powders that build around the terminals of your battery can be a sign of trouble. Just because there is corrosion on the battery surface doesn’t mean it is dead. However, you can count it as an alert and check it quickly.

Sometimes you may need to replace the case of the battery if there is any crack. The crack mainly occurs due to the gas emission of the engine. Make sure to clean the battery posts properly.

Excessive Consumption of Electric Power

You might have already known that power is supplied to mower components such as headlights and horns by the mower’s electrical system

However, the battery energy is used even after the motor has been turned off. Hence, the battery will die quickly if you keep on the headlight or horn switch, making the battery drain faster.

Damaged Battery

If your lawnmower battery is partially or almost damaged, it is high time to replace it. It might be already lost its capacity to hold enough charge. So, its life cycle is going to meet the endpoint.

When your lawnmower battery is damaged, the charge doesn’t last long as it used to be. An important piece of information you should know is that the life expectancy of most lawnmower batter is around 3-5 years.

With proper care, you can use the battery for up to 5 years. You want to keep the battery separated during the winter season when you are not using it. In addition, keep it a safe place where no freezing will occur.

So, these are all possible reasons for this question: why is my lawnmower battery dying?

What Would Drain A Lawnmower Battery?

Most lawnmower comes with a lead-acid battery. When you fail to start the machine, a drained battery may be a probable cause of this issue.

Your lawnmower is supposed to charge the battery when you are operating the machine. Sometimes it happens your lawnmower is draining the battery though you are not using the mower.

Different reasons can cause the question of what would drain a lawnmower battery.

Forget To Turn Off The Headlight

One of the possible reasons is to forget to turn off the headlight after using the mower. When the headlight is on for a long time, the mower battery keeps draining.

Some lawnmowers may have a Smart system to turn off the headlight when the machine is not used for an hour or any specific time. However, if your lawnmower doesn’t have this feature, the battery will keep draining until you turn it off.

A Short Circuit

The lawnmower battery may be drained by too much current draw caused by a short circuit. In that case, you want to check out whether there is any loose connection for the charging systems.

Too Hot or Cold Temperature

When the outside environment is too hot or too cold, it may show issues for your mower battery. If you purchased the battery recently, it could withstand more extreme temperature fluctuations in the seasons.

On the contrary, old batteries won’t be as effective as new batteries. Because they will be vulnerable to extremely hot or cold temperatures. The charging cycle may slow down. And, the battery may die eventually as it can’t withstand the temperature.

Not Charging While Mowing

It is a common function for a mower battery to get charged when the machine is on. The alternator helps charge the battery.

If the alternator is not working correctly, the battery may not be charged. As a result, you will struggle to run on the machine.

Unless there is sufficient power on the battery, you won’t be able to start the mower. So, figure out whether any problem with the alternator.

Cranking The Mower Excessively

A considerable amount of power is required to start a lawnmower. Using your mower for a short time frequently may stop the alternator from charging the battery.

Though an alternator is supposed to charge the battery, it can’t do it because you are running only briefly.

The problem mainly occurs among the old batteries as they don’t have much resistant power like new batteries. Plus, newer batteries are equipped with the latest technologies for fast charging when the machine is on.

Decrease In Performance

You can’t expect the same level of performance from a battery. Over time, its quality will deteriorate, and the charge cycle will also decrease.

After a particular time, the mower battery will be completed damaged. Then the battery needs to be replaced.

So, this list contains all the reasons for this question: what would drain a lawnmower battery?

How Long Should A Lawnmower Battery Last?

There is no such thing that lasts forever, and it is also true for a lawnmower battery. After a specific time, you will have to charge the battery.

How long should a lawnmower battery last?

The life expectancy of a lawnmower battery is around 4-5 years with proper care.

Your mower battery lifecycle depends on —

• How properly it is cared for
• How good the battery cell is
• How frequently you used the machine

Gradually, you will notice the battery performance is decreasing. Because there is no longer as much battery life as there used to be. Regularly using your mower gives you an idea of the perfect time for replacing the battery.

Some batteries may show less charge holding capacity within a short time. Under this situation, possibly bad battery cells are to blame. If your mower has a warranty, you should contact the manufacturer to demand replacement or repair.

Lastly, without adequate care, the battery will drain fast no matter how good the battery quality is. Hopefully, you have learned everything about this question: how long should a lawnmower battery last?

Why Won’t My Lawnmower Battery Hold A Charge?

A lawnmower battery is supposed to hold a charge for a reasonable amount of time so that you can start the machine. Have you ever experience this situation: your lawnmower battery drained even after using it only once or twice?

Why won’t my lawnmower battery hold a charge?

Multiple factors can cause the reason for a run-down battery —

• Your battery charge is consumed by headlamps or horn of your mower when it is off
• While using the mower, its battery is not recharged
• The alternator of the mower is not functioning properly
• The lifecycle of the battery comes to an end (need a replacement)
• The battery has a defective or blown fuse

So, these are probable causes when you are wondering—why won’t my lawnmower battery hold a charge?

Why Do Lawnmower Batteries Not Last?

Why do lawnmower batteries not last or why is my lawnmower battery dying – whatever ask, the problem is is crucial.

As we have already mentioned, lawnmower batteries will not last a lifetime. As long as it holds the charge to start for the machine, you can use it. But when you notice the charge cycle is not up to the mark you desired, it may be an early indication to change the battery.

Here we are discussing some key factors of this question: why do lawnmower batteries not last?

Limited Lifespan

You have already known that lawnmower batteries can last up to 5 years. But the lifespan can be short than five years—

Environmental Conditions

According to garden experts, lawnmower batteries’ long-lastingness depends on environmental conditions. If you live in too much heat weather conditions, the battery will die faster than in colder areas. However, lawnmowers are not heavily used during the winter season.

Excessive Vibration Of The Mower

Does your lawnmower vibrate excessively when you use the machine? A battery has several cells. Parts of the battery may break down due to high vibration.

To prevent the battery from moving, you can use special hardware. When the battery moves too much, its wires may become loose, which will cause poor conditions.

Malfunctioning Charging System

A malfunctioning charging system is not a common thing, but it can happen for your mower. When this problem occurs, your mower battery either becomes over-charged or under-charged. Plus, the function fails to control the charging rate of the battery.

Both cases will affect the lifecycle of the battery. As it is a technical issue, you may not understand it unless you are an expert in this field.

Installing Incorrect Replacement Battery

After a particular time, we need to replace the battery and ensure that you didn’t make any mistake installing it.

Most lawnmower comes with lead-acid batteries, but few of them have exception too. Because it depends on the manufacturer preference—which type of battery they want to use.

It is best to choose the battery recommended by the manufacturer. Installing the wrong type of battery may affect the engine’s performance. And it may be far away from the expected performance, unlike the old battery.

Installing The New Battery Incorrectly

It is said you shouldn’t touch things that you are not master on it. If you don’t know how to install a battery in a lawnmower, it is better to let the professional do it.

Installing a new battery incorrectly may decrease the battery’s lifespan even though the battery is helping to start the engine.

But it will not continue for long, and that’s why you want to hand over the task to an expert. Either take it to a nearby shop or get a professional service at home.

So, it is essential to know— why do lawnmower batteries not last? You can take the right step to handle the situation based on the cause.

Can You Fix A Dead Lawnmower Battery?

A lawnmower battery is supposed to provide service for a particular time. Once the time is over, there is no going back, and you can’t fix it. However, sometimes you may mistake the battery condition and think it is fully damaged (but actually not).

Can you fix a dead lawnmower battery?

Whether you can fix a dead lawnmower battery or not depends on how ‘dead’ the battery is. Unless the battery is entirely defective, you can charge the battery with a rectifier for several hours and take a “load test” for the battery.

If the battery doesn’t face any issue for the “load test,” you can use it again for your mower. Several decades ago, it was common for technicians to replace the defective cells in dead batteries.

However, as the technology improved, it is an uncommon practice to do it. Plus, plus the process is time-consuming. Replacing is the best if the battery is completely damaged.

In addition, due to the Smart system on the latest battery, even if some battery cells are defective, you can use the battery as long as other cells are fine. Hopefully, the fixing concern of this question is gotten cleared: can you fix a dead lawnmower battery?

How to Perform an Alternator Test on a Briggs and Stratton Engine

If you’re experiencing problems with the electrical system on your Toro turf equipment, the problem may be a bad alternator or a bad battery. These problems can include:

• Hearing a click or groan when starting the engine
• Battery is not charging or is draining too quickly
• Electronics on the equipment are not functioning properly

You can quickly determine if the alternator and battery are functioning properly by performing simple tests. The following describes two methods for performing an alternator test on a Briggs and Stratton engine. For the battery testing procedure, see our blog post on battery testing.

Note: Be sure to check all safety warnings in your equipment’s operating manual before performing any work on the electrical system or engine. Contact an authorized dealer for assistance if you have any questions.

For a quick-and-dirty alternator check that can be done without any testing equipment, simply start the engine and turn on the headlights on the piece of equipment you are testing. Then, turn off the engine.

If the lights dim, then the alternator is probably working properly. If the lights do not dim, then it probably means that they were actually being powered by the battery even when the engine was running, and thus your alternator is probably not functioning properly.

For a more accurate test, if you have the proper equipment, you can follow the following procedure.

Step 1: Connect a charging system voltage multi-tester to the engine

For a Briggs and Stratton engine look beneath the blower housing above the starter on your engine for the connector that is attached to the stator (yellow wires). Disconnect wires from the voltage regulator for testing purposes. Set the Multi-meter to check for AC voltage coming out of the stator. Reference your Briggs and Stratton service manual for proper AC voltage specifications on your specific machine.

For an AC Volts test, set the tester’s dial to AC volts and connect one end of the black multi-tester lead into the tester’s COM receptacle and the other end to ground. Then connect the red lead on the multi-tester to the tester’s AC Volts receptacle, and the red lead to the appropriate stator output wire.

Step 2: Start the engine

Start the engine of the piece of equipment that you’re testing. Then, use the tachometer to set the engine test speed to Toro specifications (located in the service manual). Perform charging system test as outlined above and verify the AC output is above minimums. If the reading is below the minimum range the stator is bad and must be replaced before further testing can be performed.

Step 3: Turn off the engine

After the test is complete, shut down the engine and disconnect all the equipment.

Following the steps outlined above will tell you definitively whether or not there is a problem with the alternator on your equipment. To determine if there is a problem with your battery or a diode, follow the procedure outlined in our post on battery and diode testing.

How to Test a John Deere Voltage Regulator (5-Step Guide)

The voltage regulator controls the electrical current coming from your John Deere lawn tractor’s stator so that its battery will be charged with a smooth current that won’t damage it. Thus, it’s critical to test it regularly to verify that it’s in good functioning order and that, if a problem arises, you can address it quickly to prevent more damage to your vehicle.

In general, you can use a voltmeter to test a John Deere voltage regulator with these steps:

• Locate the voltage regulator
• Connect the voltmeter’s black lead to the ground
• Connect the voltmeter’s red lead to the furthest prong
• Transfer the red lead to the middle prong
• Transfer the red lead to the closest prong

In this article, let me discuss how the voltage regulator works and give you more details on the process of testing your John Deere voltage regulator.

Steps to Test a John Deere Voltage Regulator

When you test the voltage regulator lawn mower, knowing how to use a voltmeter is required. Now, let’s test the AM102596 John Deere voltage regulator as an example. Here are the steps:

Step 1: Locate the Voltage Regulator

Park your John Deere on a hard and level surface. Then, set its parking brake and remove the key from the ignition. Raise the hood and look for the voltage regulator on the right side of the engine. You can locate the regulator in the little silver box attached to the engine’s side.

Step 2: Connect the Voltmeter’s Black Lead to the Ground

Disconnect the voltage regulator’s plug from the bottom. Then, turn on your voltmeter and set it to the Ohms scale. Look for the ground wire under the bolt that secures the voltage regulator to the engine block. Connect the voltmeter’s black lead to the bolt with the ground wire underneath it. Then, you can find three prongs under the regulator.

Step 3: Connect the Voltmeter’s Red Lead to the Furthest Prong

Connect the voltmeter’s red lead to the prong furthest from the ground. The voltmeter’s reading should be 31.2 M. If that isn’t the result, you should replace the voltage regulator. But continue to the following step if the reading is correct.

Step 4: Transfer the Red Lead to the Middle Prong

Maintain the black lead on the ground while moving the red lead to the middle prong. The voltmeter’s reading should be in the range of 8 to 9 M. If not, the voltage regulator should be replaced. Continue to the following step if the reading is correct.

Step 5: Transfer the Red Lead to the Closest Prong

Still, keep the black lead on the ground and move the red lead to the prong closest to the ground. Examine the results. The voltmeter’s reading should be between 8 and 9 M. If that’s not the case, the voltage regulator will need to be replaced. But if all of these readings are correct and within the standards, your voltage regulator is in good condition.

Bonus Step: Test Through Its Battery

You can also perform a John Deere voltage regulator test through its battery voltage. Here are the steps:

Step 1: Set Up Your Vehicle

Make sure you park your vehicle on a flat, hard surface. Turn the ignition key to “off” and set its parking brake.

Step 2: Load the Battery

Return to the “neutral” position with the foot pedal. Then, raise the tractor’s hood and turn the ignition key one position over to turn on the mower’s headlights without turning the engine over for 15 seconds to put a slight load on the battery.

Step 3: Set and Connect Voltmeter Leads to the Battery

Turn your voltmeter on. Then, set it to the 50 DC scale. Connect the voltmeter’s positive red lead to the battery’s positive terminal. Then, connect the voltmeter’s negative lead to the battery’s negative (-) terminal.

Step 4: Check the Voltmeter Reading

Start your vehicle’s engine and set the throttle to its fastest position. Over five minutes of operation, the battery voltage should remain between a 12.2- and 14.7-volts DC reading.

FAQs

What exactly is John Deere’s voltage regulator (for a lawnmower)?

The voltage regulator of a John Deere lawnmower ensures that the machine’s battery receives a steady, continuous charge. It runs on a 12-volt system to keep its battery charged. To send back to the battery, the stator on top of the engine must generate 14 volts. The 14-volts must first pass via the voltage regulator, which evens out the voltage-current, ensuring that the battery and electrical system are not damaged. (1)

In my example, which is the AM102596, it’s a voltage regulator used on single-cylinder Kohler engines seen on John Deere lawn tractors. The voltage regulator regulates the electrical current flowing from the stator, ensuring that the battery is charged at a steady rate that will not damage it. (2)

How to Wire a Charging System on a Lawn Mower

In this post, we will explain how to wire a charging system on a lawn mower. For the battery to charge, it needs to connect with the alternator and vice versa. The process of doing so is fairly easy and can be done in an afternoon. First off, remove any wires that are not being used from under the dashboard where you plan on installing your new charging system. Next, install a fuse box in that same area which should have three slots: one for power going into the ignition switch; one for power going up to the starter relay; and one for power going from the ground back down again through the wiring harness connector at the front of the engine compartment. To get started with the whole process, read below! Summary: If your lawnmower needs a charging system, there are a few different ways to go about it. The simplest way would be to buy a pre-wired system, but this can be expensive and may not be compatible with your specific lawnmower. Another option is to wire the system yourself, which is easier but may require more technical knowledge.

How Does the Charging System Work on a Lawn Mower?

The charging system on a lawn mower is responsible for making sure the battery stays charged. This is important because the battery is what starts the mower and provides power if the electric starter fails. The charging system does this by using a generator that produces electricity as the mower is driven. The voltage regulator controls how much energy reaches the battery and thus limits the available starting amps. If more amps are required for starting, the regulator sends them from the battery and keeps it charged. When you turn off your lawnmower, the generator field stops generating electricity. However, the cooling fan continues to run, using the generator field as a motor. This can cause the generator to overheat and burn out if left idle without a load. If you notice that your battery dies over time as you idle your mower, it is likely due to a faulty voltage regulator. The actual generator contains a spinning rotor and stationary field coils. The rotor spins inside of magnetic lines of flux produced by the coils to generate an electrical current. This current flows through cables and creates a voltage drop across wires in its path, causing power loss. The voltage regulator is responsible for sensing the voltage drop and signaling the generator field to produce more power. If it doesn’t do this, the battery will eventually drain when you idle your lawnmower. If you’re interested in the procedure of how to wire a charging system on a lawn mower, then read on for more information.

Five Reasons Why Should Wire a Charging System on a Lawn Mower:

Wiring a lawnmower charging system is crucial and can save you money and time. Below are five reasons why: 1. A new battery will make your mower run like it did when it was new, but without the added cost of buying a new one. 2. A new battery will keep your mower running like new by keeping the motor in good condition. 3. You won’t have to buy a re-manufactured or used battery, which often is defective and shortens the life of the mower. 4. Without electrical power, your lawn mower causes more harm than good. 5. Most manufacturers recommend that the charging system be tested at least once a year or after every 50 hours of mower use.

Things You Need to Know Before Wiring a Lawn Mower Charging System:

Here are some things you must know before taking actions on how to wire a charging system on a lawn mower: 1. The higher the number on the ampere-hour (Ah) rating of your battery, the longer it will last when starting your lawnmower engine. 2. When wiring multiple batteries in parallel, it is important to use batteries of the same voltage to avoid damaging the system. 3. When wiring multiple batteries in series, the voltage doubles, and the ampere-hour rating is cumulative. 4. The total length between your lawn mower’s charging system components can affect spark plug life. Make sure all connections are as short as possible to reduce resistance and increase the life of the spark plug. 5. When wiring a charging system to a lawnmower, you must be sure that your coil and capacitor are compatible with your battery’s voltage. 6. Always use an ammeter when testing or troubleshooting any electrical circuit on a lawnmower. You can get one at most hardware stores for under ten dollars. 7. Always disconnect your battery’s negative cable before working on any electrical components on your lawn mower. 8. You can use crimp connectors or solder to connect wires together, but soldering will provide the best connection for electronic components like diodes and transistors used in charging systems on lawnmowers.

Procedure for How to Wire a Charging System on a Lawn Mower:

Step One: Unplug the Sparkplug Wire

Be sure to disconnect the spark plug wire from the spark plug before starting the mower. If you don’t, the mower could start unexpectedly and cause injury or damage.

Step Two: Remove the Battery

Remove the battery from your lawnmower. This may vary depending on your specific mower model, but most require that you loosen a bolt on each side of the mower with an adjustable wrench. Lift the old battery out; dispose of it properly at a recycling center or auto parts store.

Step Three: Identify the Battery Posts

Identify the positive (red) and negative (black) battery terminals on your mower’s battery. You will wire your new battery to these posts to power your lawnmower motor.

Step Four: Attach the Ground Wire

Attach a cable tie to the negative battery post, then run the cable tie through an empty slot on your multimeter’s case. This will keep it from getting lost. The ground wire needs to be attached to the negative post of your mower, or else electricity can’t flow into or out of your batteries.

Wrap one end of an 18-inch wire around the negative post on your mower and tighten with a set of pliers. Wrap the other end of the wire around the multimeter’s case.

Step Five: Check all Grounds and Connections

Check all of your grounds and connections to make sure they are secure. If you find any loose connections, tighten them with a wrench or pliers. If you find any broken wires, attach new ones to the old wire using a set of crimp-on wire connectors. Crimp each connector on tightly, then cover it with electrical tape.

Step Six: Attach Both Battery Wires

Attach one end of another 18-inch wire to the positive battery terminal on your lawnmower. Then wrap the other end of the wire around the positive terminal of your new battery. Using a pair of pliers, tighten both ends onto their respective batteries.

Step Seven: Test the New Charging System

Turn on your multimeter’s switch and check for current using one of two modes on your multimeter – either DC amps or AC amps. Next, check that the voltage of both your mower’s battery and the new battery is the same. If they are, congratulations! You have just successfully wired a lawnmower charging system.

Your lawn mower should now be able to start for what will feel like forever! Enjoy hours upon hours of freshly cut grass, knowing that nothing will stop you from mowing the lawn. With a wiring system you helped create, your lawnmower runs like new.

A Couple Important Tips to Remember:

Make sure to keep all of your grounds and connections clean and secure at all times.

Always check for any broken or frayed wires before beginning a project. Frayed wires ings can cause a short on your battery, which can explode or catch fire.

Always replace all of the old wires from the previous charging system with new ones.

If your battery is completely dead, you might need to hook it up to another car or some other device that can provide enough juice for it to turn on.

Always conclude a project by running the motor for a short period, not more than five minutes at most, then turning it off and rechecking all connections before trying to start the mower.

When replacing wires, make sure to place them in the same spot as their original location and follow the original wiring pattern. This will help keep your lawnmower in proper working order.

How Do You Hook Up a Lawn Mower Charger?

Before you hook up your lawn mower battery charger, you need to know the voltage of your battery. The voltage is usually stamped on the side of the battery in raised numbers. If it isn’t, check around the base of the battery for a sticker that will have this information on it.

If no sticker can be found, measure the voltage with a voltmeter. The battery’s voltage will determine which charger you’ll need to get, either 6 or 12 volts. Most riding lawn mowers have 6-volt batteries, while most push-type lawn mowers have 12-volt batteries.

To hook up your battery charger, disconnect the negative cable from the negative post on the battery and connect it to the negative post on the lawnmower battery charger. Then disconnect the positive cable from the positive post on the battery and connect it to the positive post of your lawn mower battery charger.

Many chargers have a polarity light to indicate whether or not you have hooked up your cables correctly. If there is no light, check to ensure that you have hooked your positive cable to the correct port on the charger.

Conclusion:

The wiring on a lawnmower can be challenging to work with. However, by following the step-by-step instructions provided in this guide, you should have no problem completing your project safely and successfully.
