How to find out the date of manufacture of a Bosch battery
The date of manufacture of a Bosch battery
the storage life of batteries is limited due to the chemical processes that take place inside. The date of manufacture of a Bosch battery is determined by the marking, which is shown in coded form on the body of the product. The absence of regular recharging and unknown storage conditions undermine the durability and integrity of the battery.
“Tubor” (“Cobat”, “Titan”)
The date of manufacture markings on Nizhny Novgorod batteries are imprinted in the center of the cover, using a printer. The code is shorter than for previous batteries, but no less puzzling.
It has this form: 12345, where
day of the week, 2,3. number of the week of the year, 4. year, written in Latin letter (2014 (Z), 2015 (P), 2016 (A), 2017 (S), 2018 (T), 2019 (X), 2020 (L)), 5. shift number.
Possible marking: 418P1. You can tell from it that the battery was produced on Thursday of the 18th week (roughly, the beginning of May) 2015 by the first shift of workers.
Deciphering of additional encodings
In addition to the 13-digit serial number, there is a six-digit code of numbers (SAP) and a four-digit code of letters (FIFO).
- SAP. Internal vendor number, which they need for their needs. They can find all the information about the batch in their database, and if there is a problem, they can easily recall the defect.
- FIFO (First in. first out). It contains the date of battery activation, which is necessary so that the first to be stored in the warehouses would be the ones shipped first.
The activation date is encrypted in the first character, the other three are for internal use.
How to determine the date of manufacture of a battery?
The Eurostart battery cipher has two groups of numbers: one is a four-digit number, the other is a four-digit number. Six digits, for example: 3597 514226.
The model of the marking of the date of manufacture of the battery:
First half of the year: 1. Jan, 2. Feb, 3. mar, 4. apr, 5. may, 6. Jun
Second half of the year: 1. July, 2. avg, 3. Sep, 4. Oct, 5. november, 6. dec
Battery produced on mower line number 3, personal batch code. 376. Year made: 2014, second half of the year, month number 4, October 26, 7 brigade.
Heavy batteries are marked differently.
For example, the heavy batteries are labeled like this: 13512254
Battery with a capacity of 135 Ah, made in 2012, second half of the year, month 5 (November), brigade number. 4
Due to the relocation of the plant to Kursk, there was a change in marking in 2015: 1117 6 74621

How to determine the exact date of manufacture from the marking on the battery cover
Many people wonder how to determine the year of manufacture of a battery by battery marking. Nothing but strange numbers on the plastic box. In the store they always claim that the goods are fresh. Or they say that the battery has no expiration date at all. Who to trust and what to do not to run across a counterfeit, and then not to buy an expensive battery a second time is an important question for a car owner.
Having found out what this or that number means on the box and why it is so important to know the year of manufacture of the battery, as well as having understood the codes of the most popular producers of batteries, you can choose a good battery without the risk that it may run out at any moment.
How to find out the date of manufacture of a car battery?
In a chemical current source there are reactions that lead to wear and tear of the electrode plates. Over time, the battery loses capacity and becomes unsuitable for further use in a car or stationary installation. A code marked on the casing indicates the date of manufacture of a battery, thus preventing the purchase of an expired product.
How to know the date of manufacture of the battery?
The battery is not meat, nor is it a loaf, but it too has its own shelf life.к. Inside this small but heavy box are continuous chemical reactions and processes.
Therefore, when buying a starter battery (battery) you need to pay attention to the date of manufacture. Overdue battery, as in the case of meat and loaf. it is a waste of money and time. A “lying” “not fresh” battery can “run out” at any minute. And, for lead-acid batteries made according to the traditional technology with the addition of antimony, the shelf life should not exceed 6-10 months. If the battery has silver-plated plates it is 12-15 months. Well, and in the case of calcium batteries, their self-discharge is minimized, but still within a year or two such batteries sat down almost to zero. But it is not necessary to take these storage times as a constant. In many ways, the shelf life (without periodic recharging) depends on the conditions in which the battery is stored.
As a general result the consumer characteristics of the battery in 2-3 years of storage deteriorate so much that it is not recommended to buy a battery that has lain during this or a longer period of time. Of course, there are exceptions, for example, Bosch AGM batteries practically do not lose the charge even after 3 years.
In other words, it is not recommended to take “lying” goods, as well as when buying a battery of any freshness before installing it on the car is highly recommended!
All the necessary information will be given by the battery marking. There are no unified standards for marking the date of manufacture of a battery, it is placed differently on different batteries. Most manufacturers indicate the date of manufacture of the battery in the form of a set of letters and numbers, and sometimes as a color marking.
The date of manufacture of the battery can be indicated on the front label, embossed on the cover, or placed on a separate label on the side wall. No standards here.
The most common ways of encrypting the information:

How to know the date of manufacture of the battery by marking
Each battery manufacturer puts a special code on its battery, which is called the marking. Technologically, the marking can either be burned out by a laser (such as the marking on the Tyumenskmo Medved) or melted into a die (as in the Kursk batteries). As a rule, the marking of the date of manufacture is put by the fact of readiness of the battery, that is the actual, but in practice some factories commit a sin and put the date of manufacture from the future, which allows you to sell “fresh” batteries, albeit manufactured 2 months ago, from the factory. Most likely this is done in the summer and fall period in order to optimally load production and stock the battery for the season.
It is believed that the fresher the battery, the higher its value, so often, at low attractive trying to get rid of old batteries. During storage, the battery loses some of its capacity due to chemical processes going on inside. So, for example, the batteries, made by hybrid technology can be stored without loss of quality for 6 months, calcium batteries. 12 months. At the same time Johnson Controls (manufacturer of Warta, Bosch, Energizer and other brands) says that their batteries can be stored for 18 months. In fact it is only a marketing ploy and a tool to facilitate the sale of “stale” batteries by dealers, which get on the shelves of stores through a long way.
So, when going to buy a new battery, be sure to take a printout of the battery’s release date markings to the store. This will allow them to make the right choice.
In addition to marking release dates, the battery has markings according to accepted standards (GOST, SAE, DIN, EN, JIS), about which our website will write a little later.
This article gives examples of markings used since 2014, as in 2015 there were serious changes in the battery market, and some owners of private brands have changed factories-manufacturers.
Japanese batteries
The Japanese Panasonic and FB batteries have it much easier than the Korean ones. The date of issue is stamped on the bottom of the battery in the form of six digits XXXXXXXX.
Panasonic
The code of the type 123456, de 1 and 2. year, 3 and 4. the serial number of the month, the 5th and 6th. Example, the battery is stamped 170425 on a Panasonic battery, which means the battery was manufactured on April 25, 2017.
