A car battery typically has a capacity of 60 AH and 12 V. The power output is 720 Watt-hours, lasting up to 120 minutes on average. This will depend on how much you use your headlights and other accessories you have in your car. To understand the number of car battery watts to run off, determine first what amps your battery can produce.
So, if a battery operates at 12 volts and provides 50 amps of current, the power output would be 600 watts (12 volts × 50 amps). In summary, the power of a car battery is measured by its voltage and capacity in amp-hours, and you can calculate wattage by multiplying these two values.
These batteries range between 40Ah to 110Ah while the alternator can charge the battery at a rate of 45amps to 200amps.
