M3 E92 2012 - What Battery is this?
Hi,
BMW E92 M3 2012 DCT ZCP - GCC Middle East (Non Start Stop) Can anyone tell me what type of battery this is? I want to give it a charge, since the car isn't out much since March. (No problems or anything). My charger is a Ctek. I have an AGM mode and a normal mode. From the forum, this battery should be AGM, but I do not see AGM wrote on the battery anywhere. Pics attached. Thanks |

Can't tell the brand name of the battery from your photo but it looks like the same blue top Bosch battery I have in my M. Eitherway it's an AGM battery. Use the snowflake setting.

Its a Bosch S4 H42 I can't find anything Bosch S4 that says AGM. For the Ctek, I was going to press Car Battery + Recon Last edited by gaz_0001; 11-21-2020 at 08:16 AM.. |

I have a ctek 25000 and I believe it just auto detects the type of battery. It's basically got normal mode that just does the right thing, recondition a battery mode, and a supply mode to supply power ( I think that could be used to supply constant power for coding? ). In theory the normal mode should detect the battery and do the best thing based on the state of the battery.

I charged it fine with the Regular & Recond. I'll upgrade to AGM soon - this one is at least 3 years old now....maybe more. |

The tube is just on the side by the positive post. They have been fantastic batteries. I'm a little worried since Pep boys dumped bosch, so I have no clue what is a good alternative now.

Replaced a Bosch AGM with a Duralast AGM and both had the vent, so that's not a good indication.
Any way to undo some of that hardware to get a better look at the specs and part number?
