Automotive batteries are usually adequate for small inverters, (< 500 Watts). When used in a car, we suggest you run the vehicle of your engine occasionally while operating your inverter. If you use the inverter while the engine is off, you should start the engine regularly and let it run to charge the battery. Deep Cycle (marine) batteries are best for larger inverters as they are designed for several hundred charge/discharge cycles. (Automotive batteries wear out much more quickly after heavy discharge).
