They need to be "Equalized" how to do that on your system I do not know. I know how I'd do it but it requires hooking them in parallel to a DIFFERENT charger.
Don’t equalize AGMs. It will damage them.
You are mistaken. They need to be equalized. But the procedure is different for those batteries.
Basically they need to be charged independently on a 12 volt charger
or charged in parallel on a 12 volt charger.
Charging them in series when they are not equally discharged results in one being over charged and the other under charged.
I see people yammering about different size 12 volt batteries in parallel. they make the very claim I just stated.. Which is not true for batteries in parallel.
But batteries in SERIES need to be identical
Same size
Same capacity
SAME STATE OF CHARGE. (Equalized).
And the easiest way to do that is to put 'em in parallel and use a 12 volt charger.
