[QUOTE="apprentice87, post: 464080, member: 13534"] AH ratings are a bit lettuced anyway. The thing might well churn out 1 amp for 110 hours, but will never do 110 amps for an hour.. Anyway, so far as i can remember, "flat" in the world of car batteries, is 1.8 volts per cell. You need to hook your inverter up when the thing is fully charged and leave it untill the terminal voltage drops to 10.8V and then do your maths.. john.. [/QUOTE]
