6 Maintaining Battery Condition
Here are some guidelines that will help to preserve your battery.
Using vehicle batteries
• Vehicle batteries are not designed for repeated deep-discharge
cycles, and constantly recharging a vehicle’s battery will shorten its
life. Therefore, when you are using a vehicle battery as a power
source, start the vehicle every hour or two to recharge the battery.
•The XPower 450 will operate while the engine is running, but the
voltage drop that occurs when the engine starts may trigger a low
voltage shutdown.
• Vehicle batteries are designed to provide brief periods of very high
current needed for engine starting. They are not intended for
constant deep discharge. Regularly operating the XPower 450 from
a vehicle battery until the low voltage alarm sounds will shorten the
life of the battery. Consider connecting the XPower 450 to a separate
deep discharge type battery if you will be frequently running
electrical products for extended periods of time.
Minimizing power draw
• If you are not going to use the XPower 450 for more than a week,
turn off the On/Off switch. The inverter draws less than 0.2 amps
when the On/Off switch is on and no load is connected, but it will
eventually discharge the battery.
