Battery Operating Time - Energizer ENA548 Owner's Manual

CAUTION
Although the ENA548 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 ENA548 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.
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 ENA548 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.
