Charge rate for two different battery groups with different ah rating
I have a Xantrex XW4024 off grid backup system with 4 Trojan L16RE-b’s rated at 370ah each.
2 weeks ago I purchased 4 Trojan T105 plus batteries rated at 225ah for scrap with hope of reviving them.
When I received them I checked the Sg and it didn’t register so I proceeded to charge them at 32 volts and discharging them several times.
They recovered and now have approximately 80% capacity.
My question is what rate should I program my charger for with the battery banks connected parallel? The total ah rating for both battery banks is 595ah.
Should I program my charger at 595ah or leave it set at the current setting of 375ah.
