1.2V per NiMH and NiCad cell. 2.1V per lead-acid cell (car batteries are 6-cell (12.6V) and some golf carts are 3-cell (6.3V)) Finally, multiply the voltage (V) by the amp-hour (Ah) rating of the battery/pack to get watt-hours (Wh) and then compare. For example, the Switch 8 Solar Recharger is 3.6V and 2.2Ah (2200 mAh) By multiplying those two together you get 7.92W.
Milliamp-hours is a measure of current capacity over time. It is a representation of how much total charge a battery has. If you use the battery to operate something that doesn't require much current, it will last a long time.Be aware that batteries (cells, really) have a nonlinear depletion characteristic.or example, if you draw 1 mA for 1 hour from a battery, you have used 1 mA Â· 1 h = 1 mAh of charge. If you draw 2 mA for 5 hours, you have used 2 mA Â· 5 h = 10 mAh.
