Understanding Error LEDs.
Error Conditions will be indicated by the following LEDs.
LED
Reason/Solution
Possible battery short / Battery will not hold a charge. Have battery checked by a professional.
Battery voltage is too high for the selected charge mode. Check the battery and charge mode.
Reverse polarity. Reverse the battery connections.
Charger is in Standby mode or Battery voltage is too low for charger to detect.

Flashing
Charger internal temperature too high / Charger will resume function once the Charger internal temperature drops.
Charger ambient temperature too cold / Charger will resume function once the Charger ambient temperature rises.
Explanation
The 25% Charge LED will slowly pulse “on” and “off” when the battery is less than 25% charged. When the battery is 25%
charged, the 25% LED will go solid and the next LED will begin to pulse.
The 75% Charge LED will slowly pulse “on” and “off” when the battery is 50% - 75% charged. When the battery is 75%
charged, the 75% LED will go solid and the next LED will begin to pulse.
The 50% Charge LED will slowly pulse “on” and “off” when the battery is 25% - 50% charged. When the battery is 50%
charged, the 50% LED will go solid and the next LED will begin to pulse.
The 100% Charge LED will slowly pulse “on” and “off”, when the battery is less than 100% fully charged. When the battery
is fully charged, the Green LED will be solid, and the 25%, 50% and 75% Charge LEDs will turn “off”.
During Optimization, the 100% Charge LED will pulse “on” and “off” slowly. Once the battery is fully optimized the 100%
Charge LED will turn solid green. The charger can be left connected to the battery indefinitely.
