How to read the code of a car battery

Do you know if in our cars it is necessary to code the battery change as it has been happening for a long time in other brands. This page hints that yes, but I do not know if only in the start/stop or also in the hybrids: https://www.toyota.es/world-of-toyo…art-stop-toyota

In brands like VW, BMW… it also works without coding anything, but the battery does not last as long as it could last and the charging system does not work in the most optimal way. The battery distributors give you a code that varies depending on the battery and the date of purchase, for something.

Theoretically… the battery charging algorithm takes into account that the battery is aging and is adapting its charging processes to extend its life, so if we put a new battery, Mr. algorithm must know to take it into account… if not, it would charge a new battery as if it were old…

It is not a hybrid, there are no regenerative brakes, and its electronics does not even have the modernities of lane change warning or collision warning (the front and rear sensors are only for parking).

I admit that I was very afraid of the change to the “old”. Among other things to see that the clamps of the terminal cables to connect the battery (both positive and negative terminal) came with a shunt full of apparent relays, sensors, or whatever.

Adapt vagcom battery

Very good,I have already found how to code the battery with the OBDeleven but I have found the surprise that the BEM code does not match the one marked on the battery,I get a code of 10 numbers all the same (1) the same as the manufacturer (Moll) I get JCB as will be generic I do not know ….

I answer myself, it seems to me that putting amps and battery type should be enough, the other data I think are optional but in the BEM code should be all and it would be easier to put that one piece of information.

ThanksYou go to control unit 19 and select Adaptation,once there select battery adaptation and a screen will come up with the battery data where it is possible to change them when a new battery is put in.

I have read in this forum or in another, that to give a good charge to the battery, you should disconnect the sensor that goes to the negative pole, and drive without it. This way it does not detect anything, and gives the necessary charge to the battery. This afternoon returning from work, as it is 30km, I’m going to try it, to see what it marks when I park and put the sensor again. As I mark 80 or 90% is that it has worked.

Coding battery golf 7

quemovida6925/07/2017, 16:01Well…I have clear how to do it but I do not know what is the code of the battery I want to put. E looked in Audi sport ibérica forums they have a list of different batteries but the one I want does not come out. It is a varta silver dynamic e39.

quemovida6927/07/2017, 19:33From what I have been able to read through the forums, which has not been little…, the car carries a battery management module, in my case the module 61. In order to manage everything correctly you must tell it by coding what type of battery you carry.

tell you that the code that I had of series did not correspond with the BEM of the original battery, only the amperage and the manufacturer, the rest were all ones until completing the digits, I think that should not be important since it is the serial number of the battery, but if correctly put the amperage and manufacturer.

josulan03/09/2017, 22:22Hello all. A preguntaata quemovida69, have you disconnected the battery completely and then placed the new one, or have you powered in parallel the car with another battery or a charger so that it does not run out of current at any time? I have read somewhere that people connect a charger while the car is without the battery, because if not then there were modules that lost the coding and had to go through the official service. I have clear that you will lose the time settings and you will have to re-enter the code of the radio or the browser, but as I have not yet changed any battery to a car with Start & Stop, because I have my doubts on how to do it. I am already noticing a loss of starting power and it is only at 80% according to Vag-Com.
