Anyone know the CCA's on the starter battery? MB rates them in AH's, (105).

Oem is 800 cca. Some replacements are 850 and even 900.

Thanks. According to the Mercedes Shop Manual (WIS), cca's for the 105 AH are 950. The smaller battery called many things by MB, including starter battery, auxilliary battery, and additional battery, is just 112 AH's which would suggest cca's at just a little over 100.

Supplier for replacement battery?

I had MB replace the original battery as part of the CPO purchase deal. I did replace the auxiliary battery last Dec which I purchased from MB for $125. (Left the 5 off initially showing just $12).

Really need help to find the location of
auxiliary battery g63 2019 and newer.
