Understanding Error LEDs.
Error Conditions will be indicated by the following LEDs.
LED Reason/Solution
Solid
Charger is in Standby mode or Battery voltage is too low for charger to detect.
Solid Battery voltage is too high for the selected charge mode. Check the battery and charge mode.
Solid Possible battery short / Battery will not hold a charge. Have battery checked by a professional.
Solid Reverse polarity. Reverse the battery connections.
Charger internal temperature too high / Charger will resume function once the Charger internal temperature drops.
Flashing
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% fully charged. When the battery is
25% charged, the red Charge LED will be solid.
The 50% Charge LED will slowly pulse "on" and "off", when the battery is less than 50% fully charged. When the battery is
50% charged, the red Charge LED will be solid.
The 75% Charge LED will slowly pulse "on" and "off", when the battery is less than 75% fully charged. When the battery is
75% charged, the orange Charge LED will be solid.
Pulsing Green LED - Bulk charge complete, optimizing battery for extended life.
Solid Green LED - When the battery is 100% charged, the Charge LED will be solid green.
After the battery is fully charged, the charger will continue monitoring the battery, and provide ongoing maintenance and
optimization. The 100% Charge LED will pulse "on" and "off" slowly during these cycles. The charger can be left connected
to the battery indefinitely.
