I'm sure my batteries are at the end of their life and I'm going to replace them but I have a couple of questions. Voltage and how it relates to stated Amp hrs.
I have a 12V house bank with 6 - 6 volt deep cycle batteries. Each Battery (Trojan T-105) is rated at 225 AH (20 hr Rate).
When I'm not at the dock I charge using a generator until the (Outback Inverter) meter reads 14.1 volts.
I shut off the gen and let it set and it drops to 12.3
I have a draw (again from the Outback panel) of one amp constant (Inverter is supplying a ice maker).
I also have a DC draw on my DC meter of < 5 amps.
After 6 hrs my voltage is down to 12.2 At 10 hrs it's down to 11.9
So, if I HAD 225 AH * 6 batteries I should have had 1350 AH (Assuming the 20 hr table) correct?
If I'm using 6 Amps (metered) and drew my batteries down to 50% would that mean that I should have been able to run the 6 amps for: 1350 AH total / 6 amps draw * 50% capacity level = 112 hrs?
If I replaced all the batteries with new, how would I calculate the total time it would take to bring the battery bank down to 12.1 volts assuming a 6 amp draw?
