Battery Maintenance
When changing the input voltage wait
until all the LEDs are OFF or wait a
minimum of 20 seconds before switching
on the new voltage.
3. The charging time is affected by numerous
factors including battery Amp-Hour capacity,
depth of discharge, battery temperature, and
battery condition (new, old or defective). Batteries
larger than 240 AH can be recharged but will take
longer.
Do not disconnect the DC output wires
near the batteries when the charger is
ON. The resulting arcing could cause
the batteries to explode. If the charger
must be disconnected, first disconnect
the AC power supply cord from its
outlet, then disconnect the charger DC
connections.
Risk of an electric shock - Do not touch
un-insulated parts of the charger output
wires, battery connector, or battery
terminals.
Visually and manually inspect to verify the
DC output wires and terminals are in good
working condition before each use.
4. The charger will start automatically within four
to six seconds. The charger will start even with
severely discharged batteries (down to 1V terminal
voltage). Once charging starts, the LEDs indicate
the charging progress.

The charger goes into an equalizing charge mode after
the batteries are charged and all 3 LEDs are "ON". The
charger will continue to charge at a low current then
shut off automatically when complete. If all 3 LEDs
blink together, there is a problem.
Take proper action according to the following
instructions:
3 LEDs blink once simultaneously:
Output connection error. Check the battery and charger
connection. The output may not be connected to the
batteries or the connections to the batteries may have
corroded or loosened. The output may be shorted due
to improper connection to the batteries or pinched
wires. The output may be connected in reverse polarity
to the batteries. The charger is not damaged by any of
these problems.
3 LEDs blink twice simultaneously:
The charger is indicating that the AC voltage is too low
or too high. Check the AC input voltage.
3 LEDs blink three times simultaneously:
Charger is overheated. No action required. When
the charger cools, charging will restart automatically.
Check and correct for dirt or other debris on charger
that may be reducing cooling.
3 LEDs blink four times simultaneously:
Input or output over current. No action required,
charger will correct and restart automatically.
100% LED lamp blinks:
Charger 18 hour timer has timed out due to battery
problem.
