So I suspect my MkIII has the original battery (over 3 years old), no battery low warnings are appearing yet, but with the ignition on it is dropping to 12.2v. I am thinking it is not far off karking and would rather preemptively get it replaced rather than have the Mrs stranded, as she drives it mostly.
When it has been fully charged and left over night it will settle down to about 12.6-7v.
-Fully charged dormant: 12.6-7v
-Doors open 12.4v
-Ignition on 12.2v
Workshop manual indicates 12.5v min is required.
Currently has an AGM, 70Ah, 760CCA battery installed with 'Start Stop technology'.
I have permanently disabled S/S, does the replacement still require S/S features?
Am I safe to just get an AGM with specs of 70Ah & 760CCA? I am in a warm environment.
Cheers
