In addition, for lead-acid batteries, the Ah rating is usually given at a "20-hour rate" or less often at a "10-hour rate". This means that a 100Ah battery can only provide its 100Ah capacity during a 20h period (5A for 20h). If you connect the same battery to a 100A load, it might only last for a few minutes instead of the theoretical 1h.

A typical deep-cycle RV battery will be rated around 80 amp-hours, which in theory would supply one amp for 80 hours. However, in reality, if you discharge a lead-acid battery (what you likely have in your RV) more than 50% of the rated capacity you will greatly shorten the life span of the battery. Therefore, when calculating the reserve amp ...
But the real issue with battery chargers is a thing called battery "acceptance rate." Historically, we used a value of 25-30% of a battery''s amp-hour rate as the maximum acceptance rate. Translated, this would mean that a 100-Ah rated battery would gain no advantage connected to much more than a 25- 30-amp rated battery charger.
Using that equation, the number of watts a 12 volt 100Ah battery can provide in an hour, would be calculated like this: 100 amp hours x 12V = 1200 watts hours or 1200 watts for one hour. ... As an example though, let''s …
