### How is battery wattage calculated?

Voltage * Amps * hours = Wh. Since voltage is pretty much mounted for a battery sort because of its inner chemistry (alkaline, lithium, lead acid, and so forth), incessantly best the Amps*hour size is imprinted on the facet, expressed in Ah or mAh (1000mAh = 1Ah). To get Wh, multiply the Ah through the nominal voltage.

### How many watts is a car alternator?

at a charging voltage of around 14 Volts that yields in 560 to 770 Watts.
