Will a 12 volt battery support a 750 watt inverter?

Yes, a 12-volt battery can support a 750-watt inverter, but the current draw must be considered. A 750-watt inverter draws about 62.5 amps from the battery (750 watts divided by 12 volts). This means the battery must have sufficient capacity (amp-hours) to handle the load for the desired duration. Additionally, ensure the battery is capable of delivering that level of current without damage.
