Truecharge™ 2 Battery Charger completes a charging cycle, but the
battery voltage seems too low.
Possible Cause
Solution
Battery temperature is either too
hot or too cold for safe
charging.
If battery is too hot, allow battery to cool.
Improve ventilation or install in cooler
location.
If the optional remote panel is available, you
may reduce the output current using the Set
Max Output button.
If battery is too cold, allow batteries to warm
up.
WARNING:
Do not charge a frozen
battery. Charging a frozen battery is a
potential explosion hazard.
Possible Cause
Solution
Battery has a shorted cell.
Check the battery.
Verify you are attempting to charge a battery
correctly rated at 12 volts nominal (all 12 V
chargers) or 24 volts nominal (all 24 V
chargers). Re-check the battery voltage with
all loads removed and the battery is at rest
for about an hour.
Replace the battery.
The battery has reached its usefulness and
can no longer accept a charge.
