Battery Operating Time - Energizer EN120 Owner's Manual

CAUTION
Although the EN120/180 incorporates
protection against over-voltage, it may still be
damaged if the input voltage exceeds 16 V.
• In the event of an overload, low battery voltage or
overheating, the EN120 /EN 180 automatically
shuts down.

Battery Operating Time

Operating time will vary depending on the charge
level of the battery, its capacity and the power level
drawn by the particular AC load, USB load, or
combination of both. With a typical vehicle battery
and a 80W load, an operating time of 4 to 5 hours or
more can be expected.
When using a vehicle battery as a power source, it is
strongly recommended to start the vehicle every hour
or two to recharge the battery before its capacity drops
too low. The EN120/180 can operate while the
engine is running, but the normal voltage drop that
occurs during starting of the engine may trigger the
inverter's low voltage shutdown feature.
