Battery Maintenance
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.
WARNING
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.
WARNING
Risk of an electric shock - Do not touch
un-insulated parts of the charger output wires,
battery connector, or battery terminals.
WARNING
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 for and remove 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.
▪
Batteries do not fully charge:
If the batteries
are charged overnight, make sure the AC supply
is not being switched off at night with other
building items. Check battery condition and for
dead cells or reduced capacity. Replace charger
only if other problems are not found.
▪
The AC line circuit breaker or fuse is blown:
A
defective circuit breaker or fuse, an overloaded
circuit, or a charger problem can cause this
condition. Try connecting the charger to a
different AC outlet (on a different circuit) in the
building. If the AC supply checks good, the
charger should be replaced.
