How do you know the date of manufacture of a Bosch battery?

Explanation of the marking

In order to find out the year of manufacture of the battery, and the specific date of manufacture, it is worth using a special table. The marking is applied to the upper part of the cover in the form of 9 numbers. The required numbers are 4 through 6. The first of them reflects the last digit of the year of manufacture, whereas the two outermost ones represent the code of the month.

It is the designation of months and is contained in the table. For AGM batteries the marking is slightly different. It is located on the back of the case in the lower row of digits. The first two are the year, the second pair allows you to determine the week, the last one marks the day of the week.

The date of manufacture of the Bosch battery

Date of manufacture of the battery is very important information because each battery has a storage string. But unfortunately not everyone knows where to look for it, or how to decipher it, and some car owners do not pay attention to it. In this case, consider the marking of the date of manufacture (year/month) of the battery Bosch, because it is one of the most popular batteries. Those batteries that were produced in the past were of higher quality, but now reviews of Bosch batteries are less optimistic.

And so, how to determine the date of manufacture of the battery firm Bosch. It’s actually very simple, if you have the date decryption table.

For example, let’s take the Bosch SILVER 4 battery, a 12-volt 74 amp battery with a starting current of 680.

Bosch batteries always have a special number embossed on the top cover at the factory, which encrypts all the information about the battery. This code consists of 24 characters, the fourth position represents the year, the fifth through sixth the month.

We are interested only in the year and month of manufacture, which means only three digits encoding it. On this battery, the number is written on the front on the bottom left and squeezed off on the very top cover. On Bosch batteries, the date of manufacture is duplicated in the central part of the front label, in addition to the basic marking about the type, capacity, country of manufacturer, the battery’s purpose, it contains three digits, telling the year and month of manufacture. It is designated as C0C 559 292 1S05, and in the second line 536 242. This number can also be applied in other places on the top cover, for example on the back.

In order to decipher the date of manufacture of Bosch, we need only three digits of this number, namely the fourth, fifth and sixth. Here we have them marked as 559. When we know these three digits, we need a table to decipher the date of manufacture. Since the two letters with a number in between will only show the country where the battery was made, the assembly line number and shipping specifics. The full deciphering looks like this:

The first letter is the territorial location of the factory. Can be:

C. Ceska Lipa (Czech Republic). We have just about everything from there;

C. made at partner’s factory (Boshov batteries are all made by a partner).

This table shows the years of battery production on the left side from top to bottom, and also the months of battery production on the top line from left to right.

This table applies to Bosch batteries that have been manufactured since 2014! Because there was previously a different standard of labeling, the battery date took the fourth through eighth place in the code, with the last digit of the year immediately followed by the exact month and date. Now it’s just three numbers. And if you find the number 559 in the table, you can definitely tell that this battery was produced in November 2015. But if you do not have such a table at hand, then everything is also quite simple, the main thing to remember how to encrypt the date of manufacture. Know that the 4th digit is the year of manufacture (the last digit of the year, for example if it is 8, it means the battery is fresh, released in 2018.), and the 5th and 6th are the production month code. With the month also has its own principle: 17-January, 18-February, 19-March, 20-April, 53-May, 54-June, 55-July, 56-August, 57-September, 58-October, 59-November, 60-December.

Exactly the same as in the batteries of the company Vart, because in fact it is the same battery, since Bosch does not own factories that produce batteries, and orders the production at the factories of Varta. For example, the Bosch S4 battery in your car is a Varta Blue Dynamic with a different label.

How to determine the date of manufacture of the Battery

The code consists of two groups of digits: the first group has four digits, the second group has six digits, for example 1234 567890.Marking scheme:1 production line number2, 3, 4 individual lot code5 last digit of the year6 half year7 sequential number of month in half year:First half year: 1st January, 2nd February, 3rd March, 4th April, 5th May, 6th June Second half year: 1st July, 2nd August, 3rd September, 4th October, 5th November, 6th December8,9th day (number of month)0 brigade number (2 digits are possible)
