Symptom
Fault indicator LED illuminates. Temp and Battery indicator
LEDs flash.
Symptom
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.
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 voltage appoximately one
hour after reaching rest stage.
NOTE: If the charger is functioning
properly but the charge cycles fail to bring
the resting voltage up above 10 V, then this
confirms the battery has a damaged or
shorted cell.
Replace battery.
The battery has reached the end of its useful
life and can no longer accept a charge.
WARNING: Explosion hazard
