depende 'yan sa battery, at load mo.

kung family ng Nickel at Lithium, halos Ah rating divided by current = number of hours.

kung sa Lead Acid, medyo mahirap i-compute talaga dahil logarithmic ang curve niya. http://en.wikipedia.org/wiki/Peukert's_law kaya gagawin mo siya ng actual kung kailangan mong i-document. Wink

it's best to look at the specs of each battery. they are usually rated by the number of charge and discharge cycles. general purpose sealed lead acid batteries should have around 300 cycles. These are the ones used for UPS, emergency lights. etc.
look at the ff sites:
