charging auxiliary (alarm) 12V battery
#2
I always thought a 12 volt battery should show 14.4 when fully charged.

That is the old "lead acid" type.


Reading the Forum I discover that there are now batteries with different internal compositions, which have different end point voltages when charged.


So: maybe some internet research needed?   Do you know what kind of battery it is?
