6 Battery Operating Time
The operating time of the XPower 150 depends on the charge level of the battery, the battery capacity, and the amount of power drawn by the particular AC load being used. With a typical vehicle battery and a 150 watt AC load (like a small TV), you can expect two to three hours of operating time.
To preserve the battery:
•Do not allow your vehicle battery to become deeply discharged. A vehicle battery (starting battery) is not designed to be deeply discharged, and repeated deep discharge/charge cycles will shorten its life.
When you use a vehicle battery as a power source, start the vehicle every hour or two and run it until you have partially recharged the battery.
•Do not leave the XPower 150 on for extended periods if an AC load is not connected.
The inverter draws less than 0.18 amps with the On/ Standby switch on and no AC load connected, but that will eventually discharge the battery.
