Determining AH rating of aging batteries
My Trojan 125's are almost 5 years old now, when they were new they were rated at 240 Ah. Now my trimetric is showing 70% at 12.1 volts which I know is wrong. So how can I determine the true Ah rati...

Ok, so after 9.5 hours, the weak one was down to 1.172 or so, the rest were all 1.21, trimetric shows 52% and 12 volts no load. So I imagine by morning that voltage will creep up a little? (Bed time, work in the morning)
That voltage seems low to me for 50%, what should I be seeing no load voltage wise and 50% SOC? I thought it should be 12.2-12.3?
EDIT
OK, Google tells me 50% should be 12.1 volts
