After only 6.5 years my Passat’s AGM battery is failing.i thought i’d get longer especially since it’s an AGM, disappointing to be honest. My fathers 2007 Passat only recently changed his original battery. I suspect the fact it’s only a 69ah battery is part of the problem, i mean why do Mercedes and other models come with 80ah batteries? My car is fully loaded with heated seats and heated steering wheel etc.
Anyway my question. My battery is in the boot. I noticed it has an extra screw hole for a larger battery, does anyone know if a 80Ah would fit for sure? Anyone on here fit one or did their car come with one fitted?
For a 2016 Passat wagon (boot mounted battery) OEM parts list 2 x EFB batteries with 93ah/520a
000 915 105 EE
JZW 915 105 AE
and 1 x AGM battery with 92ah/520a
000 915 105 CE
The OEM AGM battery (68ah/380a) is 000 915 105 CC
