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.
Report Abuse. 3000 mAh means: 3000 milliampere-hours. So your battery can supply 3000mA for 1 hour, or 1 mA for 3000 hours. It is really a measure of the chemical energy stored in the battery. There is no conversion to voltage.You must buy a battery that has the same voltage as the device that you are attaching it to is rated for.o your battery can supply 3000mA for 1 hour, or 1 mA for 3000 hours. It is really a measure of the chemical energy stored in the battery. There is no conversion to voltage.
