Awesome thanks!!

Would the setup i just described be considered 3 strings?

So if i match 2x12V in a series string, i could connect to another series string of 2x12v in parallel even if they are different types, ah rating, new vs old, brand... My current bank consists of 2x12v 82.5ah + 2x12v 82.5ah for a total of 24V 165Ah. If i read correctly, i could add 2x12v 105Ah...

I'll let him know. Thanks!

UPDATE After charging as suggested above, the batteries showed 13.2V and 13.6V 4hours after they were removed from the charger. Hoping this is an indicator of minimal damage and a long life ahead!

Awesome!! Thanks

If i'm reading this spec sheet correctly... 280Ah at 10% so max charge 28A or 56A if connected in parallel?

Thanks for clarifying! Will try your suggestion!

Update... Parallel charged for approximately 3 hours. Each Battery showed same Voltage. Voltage was measured during charge (13.8) and with charger disconnected (13.4). Took batteries off the charger and removed the parallel connection. Batteries showed some improvements but were again showing...

This is different than equalization right? Pretty sure i read that these types of batteries shouldn't be charged in a four stage but just Bulk, absorption, float... makes sense?

Ju Just to be certain... Battery A's + terminal to Batt B's + terminal; Batt A's - terminal to Batt B's - terminal Positive Lead from 12V charger to Batt A + terminal; Negative lead of 12VCharger to - terminal of Battery A OR Batt B?

Yes my bad...he's connected in Series!

Thanks! Fingers crossed!

Charge both batteries before connecting the fridge? He is running a 24V inverter charger so can he still connect in 12V parallel and charge that way? Or, should he disconnect the Inverter charger altogether then connect the leads that are coming frome the charge controller to the batteries?

My friend has 2x12V batteries connected in parallel. When i checked the voltage on each batterry, one is showing 12.0V, the other 14.8V and the system 26.9. I think I know what his issue may be... he has a DC 12/24V fridge connected to one battery (yes... the one that reads 12V). My system...
