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.
An AA battery has 4.0 mA. Battery capacity is measured in mAh (milliamp hours), that's how much electricity can be delivered for how long (depending on consumption). The besâ¦t AA NIMH (nickel-metal hydride) rechargeable batteries rate at around 2100 mAh - at 1.2volts.
