How to know the production date of the Bosch battery

How to know the production date of the battery produced after 2014

Since that time, Bosch battery manufacturers have changed the rules for marking the date of manufacture:

1 mark. Manufacturing Features.

2 mark. Number of conveyor belt.

3 mark. Letter denoting the name of the plant where the battery was produced (the same as before 2014.).

4, 5, and 6 digits. Date of issue, deciphered based on table data:

The table has a search and horizontal scrolling.

It turns out that the procedure for deciphering the designation from 2014 became even more complicated, because now you additionally need to know the month code of the product. Checking this data by constantly checking it against two tables will require the motorist to be very attentive.

Deciphering of battery markings of popular brands of batteries by year of manufacture

Like all technology, batteries are subject to obsolescence. In them, this process is expressed in the fact that over time, due to the rapid flow of chemical reactions within the electrode and the electrolytic fluid itself becomes worthless. Oxidation, corrosion, reduced density of ions for exchange. all this can cause its failure. Therefore, when buying you should immediately pay attention to the date of manufacture of the battery Bosch, or any other model of the company.

Symptoms of battery obsolescence

Battery manufacturing has sufficient capacity to saturate the market with products, but to do this it is necessary to more than cover its needs. Therefore, some of the already manufactured units that are ready for shipment must spend a certain amount of time in storage. There they are stored until they are shipped to the store, but at the same time in the warehouses of the implementer can spend another period of time. Any downtime has a negative impact on battery life.There are several reasons for this:

  • Corrosion of internal elements. Metal parts are susceptible to this, as they are over-oxidized by the acids that make up the electrolyte.
  • Decrease in the density of the electrolytic fluid. can be a direct consequence of a drop in the level of charge and the formation of sludge in the bottom of the case. because the first charge can only partially remedy these deficiencies, you must be prepared to replace the working filler soon.
  • Self-discharge is one of the major woes of any battery. The state of deep discharge is considered the most harmful for modern power sources, since it can lead to a rapid loss of the capacity accumulated subsequently.
  • Storage conditions. Not all storage batteries are equally well protected from the negative effects of the environment. High atmospheric humidity and cold or heat are the main enemies of longevity of lying battery.

Any product that has been in storage for two or three years and hasn’t been sold should be scrapped, not sold. Characteristics during this period fall in comparison to the reference so much that you can not use it in cars or in everyday life. So you need to know how to determine the year of manufacture of the battery Bosch or other manufacturer.

Methods of marking

First you need to determine the material of the contacts, as it affects the maximum safe storage period. This is an important characteristic that helps to avoid errors in interpreting the results obtained by the date of manufacture. It is equal for different types:

Naturally, much depends on the way of storage, so it’s better to be reinsured and not to buy a module in which the above terms come to an end. Models are labeled differently by different manufacturers. Some knock out the necessary indicators by stamping on the plus terminal. There are those who apply them by laser directly on the case. Stickers are practically never used. with the advent of cheap counterfeiters, firms have to switch to better methods.

Despite this, many domestic manufacturers are still not squeamish to sand down the old indicators and burn out new ones on their own equipment. So you need to be careful and take into account even such trifles as the appearance of the case, which may be traces of the influence of time and environment.

Several variants are used in the application:

  • The unique code is usually ten-digit, where certain digits indicate the month, year, quarter or half year in which the unit was manufactured.
  • Colored circle. Used in older VARTA battery models, which were produced from the beginning of 2011 to the end of 2013.

To determine the date unmistakably, it is necessary to use the leaflet for each specific manufacturer. In the case of the more popular models, VATRA, Bosch and some others are considered.

Famous models

Starting in 2014, Bosch and VARTA have the new production date written on the battery casings. It is worth considering both options, since there are still older models on the market and in the segment of used equipment sales.

To determine the date of manufacture of the old Bosch battery, you need to find a special code of twenty-four characters on the top cover. The year in it will be indicated by the fourth symbol in the combination, the next two symbols. the month. For example, if it says 204, that corresponds to the fourth month, April, of 2012. If 311. then the battery was manufactured in November 2013.

In such models, as a rule, all information about the date of manufacture is duplicated on the front sticker, leaving only the three mentioned digits out of 24 there.

VARTA, on the other hand, marked the battery modules with color circles. They stood for the quarter during which the model was produced. The values looked like this:

  • The first quarter of 2011 is green.
  • The second one is red.
  • The third one is pink.
  • The fourth one is white.
  • The first one in 2012 is gray.
  • The second is orange.
  • The third is yellow.
  • The fourth is blue.

For the quarters of 2013, the scheme was taken from 2011. It is completely identical to it.

After the beginning of 2014, both companies adopted new numbering. All months have received completely different two-digit numbers to which they correspond. For example, the months from February to April are numbers between 18 and 20. From May to December. 53 to 60. Thus, the 555 is the model produced in July 2015.

2020 will receive a code of 0. All those following it are numbers in order. At the same time, the numbering that corresponds to specific months will also be shifted. For the first four it will lie between 37 and 40, for the last eight it will lie between 73 and 80. For example, a battery produced in December 2029 will be labeled 980.

The first letter is the coding of the geographic location of the factory where the module was produced. For example, G is Spanish Guardamar, F and R are French Rouen, and so on.

It is worth noting that, according to official data, to assess the potential serviceability of the Bosch battery, deciphering the time of manufacture makes no sense. The manufacturer itself has repeatedly stated that instead of paying attention to the date, it is better to simply monitor the open circuit voltage readings. If it drops below 12.5 volts, the battery may be considered unsuitable and should not be used.

VARTA applies the same principles of determining readiness for use, but adds that their products may be stored for more than a year before they are sold and start working, and all other indicators are true only for older models of hybrid and antimony batteries. The manufacturer assures that its tests show an open state voltage greater than 12.7 volts even on models that are six or nine months old. In addition, it is pointed out that there is no practice of buying only new, “not lying” models all over the world.

Other manufacturers

Batteries from Mutlu, colloquially called “mutla” by motorists, are marked with a laser that peorizes the surface on the top cover. The code has six digits, which can be understood with a short memo, because their meaning is not similar to the marking of the battery Bosch.

For example, 220524 is interpreted this way:

  • 2. the number of the production line where the battery was assembled and tested for suitability.
  • 2. year, in this case. 2012.
  • 05 is the number of the month, the month of May.
  • 24 is the number on the calendar.

Thus, this module was produced on May 24, 2012.

Portuguese “tudors”. TUDOR. have a mixed, character-numbered serial number. In the second position V to Z stands for the period between 2008 and 2012, with 2013 the alphabet starts with A. The fifth letter denotes the month, here everything is in strictly alphabetical order: A through L.

TITAN batteries from the Crimean Battery Factory have six digits in their serial number. The first two digits represent the year and the next two digits represent the month, e.g. 04 is April. The last ones represent a week in a year, not a number, so they are tied to the month.

Optima, a company from the USA, only prints the year and the day on the side of the bottle. For example, a combination of four digits 2145 is the 145th day of 2012. The A-Mega company does the same thing, with one difference. between the day and the year there is a slash.

Other ways of marking from some companies:

know, production, date, bosch, battery
  • Sznajder. the code is on the edge of the top lid. Only the last four digits are taken into account. First to third are the day and the last are the year. Because of the nature of the marking, to know the year of manufacture, you need to subtract one from the last digit.
  • Moll. four digits. The first two represent the week, the last two represent the year of manufacture. The minus terminal is stamped.
  • Exide Technologies. the concern includes many manufacturers from different countries, so it is necessary to pay attention to the presence of such a name under the name of the firm-supplier. The code has only two characters. The first digit is the year. The second, a letter of the English alphabet, is the month, from A to L inclusive.
  • Atlas. the code is on the lid, usually stamped just below the carrying handle. It consists of five characters, a space and a digit indicating the year of manufacture. The first letter in the marking is the month, also in alphabetical order, but excluding the letter I. That is, September will be marked as J, and December as K. The Bost models are marked in the same way.
  • Banner is a purely alphabetic notation. Four initial symbols on the cover decode as follows: first two letters. week, last two. year. Only characters from A to K are used in the marking.
  • Panasonic. the symbols are painted on. The code consists of six digits and one letter. Date is formed according to the principle “date. month. year”, what makes it easy to decipher for the Russian user. For example, 220212 is February 22, 2012. On the same principle models from the manufacturer SuperNova are marked with one difference. they are not drawn, but stamped by stamping equipment.

Many domestic battery companies adhere to the most understandable marking scheme. For the date of final production they take the day when the electrolyte was filled or the exact time of completion of assembly. This makes it easier to set the date.

Checking the battery voltage

If in determining the date of manufacture deciphering batteries Bosch or any other manufacturer is not possible due to damage to the label or its erasure, you can use a multimeter. This device is able to accurately measure the voltage at the terminals to assess the degree of discharging of the electrolyte and make a decision to replace it.

The way to remove the indicators is as follows:

  • Completely disconnect the battery from the electrical circuit. If you do not want to remove the battery, you can simply disconnect the common ground.
  • If the cell has been charged for two hours prior to the procedure, it must be allowed to drain the accumulated charge.
  • Connect the multimeter probes to the poles. It is not necessary to observe the polarity, because if it is reversed, the screen will simply show the result with a “minus” sign.

The results are interpreted according to the degree of deviation of the received readings from the value of 12.5 volts. If they exceed this mark, the charge is one hundred percent. When the voltage level is about 12.4 volts, it means that the battery is two-thirds charged. Under 12.3. the device is unsuitable for further use and must be replaced.

In some cases, you can refill the electrolytic fluid and repeat the measurements. If the situation has not changed and the results are still below normal, the battery definitely needs to be replaced, because it will not produce sufficient voltage.

Where to find the information and how to “read” it

To check, whose production battery on your car, you can also indirectly by this method. Most domestic plants make a fairly simple marking. It includes 4 numbers in a row, which give us information about the month and year of manufacture. complicated markings are distinguished by batteries of popular brands. For example, marks FB, Forse, UNO, Kursk plant products contain a sequence of numbers. In the first group the information about the number of production line goes first, and then about the team that assembled the product. Next is the last digit of the year of manufacture, then the 1st or 2nd half year and the number of the month in it. Without the instructions for use and to understand it is difficult.

Many domestic motorists wonder where the date of manufacture of the batteries, which are produced in Tyumen, for example, the same brand Tyumensky Bear. I will answer right away that this information is put on the cover by laser peorization method. They include 6 digits, which mean the month (the first 2) and the year of manufacture (the next 4). For example, if you see the combination 122015, it means the battery was released in December 2015.

complicated marking is distinguished by batteries known throughout the automotive world as Bosch and Varta. You can find it right on the top cover of this equipment. Just imagine, it consists of 24 characters! Of course, absolutely all of them have no practical value. In today’s article we have agreed to discuss the timing of our battery. We will be interested in the 4th figure (year of manufacture), the 5th and 6th (month in order). This information is duplicated on the colored label which is glued directly on the case.

Date of release of Russian batteries.

Domestic manufacturers often mark the date of manufacture of batteries in the most comprehensible way.

Batteries of AKTEKH plant (“AKTEKH”, “ZVER”, “DUO”, etc.).)

The deciphering of the date of production of the batteries manufactured at these two factories is the simplest and absolutely identical. Information about the date of issue is printed on the top cover in a 4-digit format. Where the first two digits. month, the second two. year of battery issue.

For example, the code on such a battery 0918, deciphered as month 9 (September) 2018.

Batteries of Tyumen Battery Plant (Tyumen Battery, Tyumen Battery (with an elk on the label))

As a rule, the code on these batteries is applied by laser engraving and is located on the side of the battery above the label or on the opposite side of the case. The code consists of seven digits, where the first two are the month of manufacture of the battery, the third and fourth are the year of manufacture, the fifth and sixth are the day, the seventh is the number of the brigade

“10”. month (October), “18”. year (2018), “20”. day, “1”. brigade number.

Ryazan Battery Plant “Tungstone” (batteries “Fora”, “Giver”, “Contact”, “Sputnic”, “Gladiator”)

Since 2016, on Ryazan plant batteries, the date of manufacture is encoded in the production code printed on the cover or side of the battery case

So code R56217.0520.1 is deciphered as follows

R. Plant code (R. Ryazan, T. Tyumen branch of the plant);

Kursk Battery Plant (“Forse”, “FB”, “FireBall”, “Uno”, “Dominator”, “ISTOK”, “Tornado”)

The code has two groups of characters. The first has a 4, the 2nd has a 6.

  • “1” corresponds to the number of the production line;
  • “2”, “3”, “4” corresponds to the batch code;
  • “5”. year;
  • “6” is the semester;
  • “7” corresponds to the sequential number of the month in the semester.

The first half of the year: 1-January, 2-February, 3-March, etc.д.

Second half of the year: 1st-July, 2nd-August, 3rd-September, etc.д.

The battery was produced on line No3, 131- batch code. 2017 production term., 2nd half-year, 2nd month, 14th. Brigade No2

A different marking is used for heavy types of batteries.

The unit has a capacity of 190 Ah, production 2018., first half year,month 3 of the 1st half year, brigade No1.

Since the production of car batteries was transferred to the Kursk plant, the variant of marking has changed.

How to determine the date of manufacture of the battery

Each manufacturer indicates the date of manufacture of the battery with its own cipher. How to know the value of the code? It is common for all batteries from one company. So you need to determine the brand, the deciphering of the date of manufacture of batteries of this company is identical.

The most common code used by several companies is a set of 10 numbers. How to know the date of manufacture of the battery by the ten-digit numeric code?

  • 1-number of production flow;
  • 2, 3,4. batch coding;
  • 5. year of manufacture, the last digit;
  • 6. first or second half of the year;
  • 7. sequential month in this half-year;
  • 8, 9. number;
  • 0. number of the brigade

Under the indicated code the manufacturers work:

Forse, FB, Dominator, FireBall, Uno, Optimum, Kursk battery. How to decipher? Substitute the information from the code instead of the sequential digits and you will get the date of manufacture of the battery.

How to determine the manufacturing date of the car battery if the numeric code is six digits? This is how the date is marked on the batteries under the brands: Tyumen Bathear, Arctic Batbear, Tyumen Bear, Yamal. Here you can see the month of the year and the year itself. 092016. October (09) 2021. Where is the date on the batteries? The six digits are applied by laser to the case, not bearing the central sticker.

The production date of the products Beast, Orion, Akteh is ciphered in 4 digits. the consecutive month in the year and the last 2 digits of the current year. 0615. June 2015. Look for the marking on the top cover.

To decipher the date of manufacture of the battery under the brands Asia, Silver, Euro Silver, Vaiper, Cobat, Titan, a mixed code of letters and numbers is used. This uses a Latin letter representing the year. So, 2014 is Z, 2015 is P, 2021 is A, 2017 is S, 2021 is T, and so on. Code 123T5 deciphered:

Where the information is located? Look at the date of manufacture of the battery on the top cover in the center.

However, there are especially complex codes, which on the date of manufacture contain all the information about a given device. The culprit of a factory defect can be determined immediately.

Varta and Berga labels: where the date of manufacture of the battery is encoded

Berga batteries are produced in the same factories as Varta batteries. Both brands have been owned for several years by the American corporation Johnson Controls, which also owns Bosch. Energizer and many other well-known brands. The Berga manufacturing date is coded identically to the Varta. On the lid of the housing at the top of the VIN code is smelted, which is a group of numbers and letters.

The first character (letter). is the name of the manufacturer:

H Hannover, Germany Hannover, GermanyC Ceska Lipa, Czech Republic Ceska Lipa, Czech Republic (Batteries, which are sold in Ukraine, produced by this very factory) E Burgos, Spain Burgos, SpainG Guardamar, SpainF Guardamar, SpainF Rouen, France Ruane, FranceSarreguemines, France Sarreguemines, FranceZ Zwickau, Germany Zwickau, Germany

Second digit. Number of assembly line where the battery came off

Third digit (letter). Order type, where this battery will be supplied: to a car factory, to a wholesaler or to a store shelf.

Berga and Varta battery issue date is encoded in the code in the 4th, 5th, 6th digits. The 4th digit is the year of manufacture (its last digit). Month of issue is encoded in the 5th and 6th digits, namely: January.17, February.18, March-19, April-20, May-53, June-54, July-55, August-56, September-57, October-58, November-59, December-60. For example, a battery manufactured in 2017 in January would be labeled in numbers 4 through 6 as follows: 717.

For batteries that are made to be installed in cars in factories and for replacement at dealerships, a simplified coding of the date of manufacture is used: just look at the minus terminal of the battery (or the case next to it). There are 2 digits.the top is a week in a year and the bottom two last digits of the production year. For example, 25/16 25th week of year 16, 6th month, June.

In Varta batteries produced before 2014, the marking on the case was different: the WIN code consisted of 13 digits and letters, arranged both in a row and grouped in the following way: 9 digits and letters and four more digits in a small gap. The first, second and third digits have not changed to this day (1st: plant name, 2nd: conveyor type, 3rd: order type). The production date itself was coded as follows (from the 4th to the 8th position in the code): last digit of the production year, month (designated by two digits), day (also designated by two digits).

Automotive battery manufacture date coding

Eternal technology does not exist, every product has its shelf life. Batteries also have their own rules of operation, because complex chemical processes take place inside it. Although today’s batteries are designed to last longer without recharging in storage, when buying a battery, pay attention to when it was manufactured.

According to the conclusion of experts, storage of normal lead-acid batteries with antimony additives is no more than 10 months. For units with silver-plated plates storage terms of one year to a year and a half. Self-discharge of calcium batteries is kept to a minimum, normal commissioning is considered up to 2 years from the date of manufacture. And for batteries made with AGM technology, the commissioning period is up to three years.

For more details about how the date of manufacture affects the service life of the battery, we told in the article “What affects the date of manufacture of the battery”

In other words, you should not buy a battery that is too stale. Remember, buying any car battery before putting it on the car, it is desirable to charge it. this will extend its life.

Buying a battery in our company. you will always buy the battery with the permissible terms of commissioning, because when replenishing the stock we take into account the amount of batteries sales and terms of their routine storage. Read reviews of our work.

So you’ve come to the store. Where to look? How to know the date of manufacture of the battery?

As a rule, the date of manufacture is stamped on the battery case. There are no set standards for the date of manufacture markings.-

Information is printed differently on many batteries. Manufacturers mark the release terms with letters, numbers, or a color marking. But how do you know how to decipher the code on the battery? There’s nothing complicated here. Most manufacturers indicate this information on their official websites.

We’ve prepared for you deciphering of production code of the most popular brands of storage batteries.

These transcripts are current as of this writing (as of 2019), t.к. The equipment at the factories periodically is modernized and production codes change, so on old models of batteries, as on batteries which will be let out in the future the codes can differ from those that are described in this article.

Additional marking

The basic numerical parameters are followed by a number of letters, which sometimes greatly affect the cost and functionality of the tool. Here is a general notation.


Actually, combinations of letters after the leading model definition:

  • A. dust extraction system (jigsaws, grinders, etc.);
  • B. bow handle, more simply called a “staple. Usually on jigsaws, routers, and other woodworking tools
  • C. speed stabilization under load
  • D. rotation lock;
  • E. electronic adjustment of rotation speed;
  • F. interchangeable chuck in the kit;
  • H is the extra straight handle;
  • I. starting current limitation, accidental start protection or anti-jamming kikkback stop;
  • J. current limiting inrush current;
  • L. higher endurance or power;
  • P. pendulum stroke;
  • R. reverse or direction of rotation switch;
  • S. set of accessories in the kit;
  • T. torque control;
  • V. vibration protection;
