If you have a halfway decent charger and you can set it to deep cycle then it will stop charging when they are charged and trickle charge them from there

12.9 to 13.2 Charger off is normally fully charged. I train mine to sit around 13.5 - 13.8

Ok so at this moment I am watching voltage display that is attached to my batteries while car is off on battery charger it is reading 14.1 does this mean batteries are fully charged

Wow, resting voltage of 14.1?

Let it sit for a bit and check again with a DMM, however if that is the batteries' true resting voltage then you are GOLDEN..

I would use an intelligent AGM charger or 2. Break up the bank into smaller sets when charging.

Take the charger off and check the voltage.
