Frequently Asked Questions and Troubleshooting Support

Q: What do the blinking lights on my charger mean?

A: All Pro, SE, XL, and Eagle Performance Series chargers display fault codes via flashing lights. Legacy chargers produced prior to 2008 have blinking lights that indicate the following:

• 1 RED BLINKING LED: No Battery Detected
  Check connections for proper polarity (black wire to negative). Contact us if the issue persists.
• 2 RED BLINKING LEDS: Forming Stage Timeout
  The charger terminates if battery voltage does not rise above 1.75 volts per cell within 3 hours. Reset by unplugging and reconnecting the charger.
• 3 RED BLINKING LEDS: Overall Timer Shutdown
  The charger terminates if the charge cycle exceeds the factory-set time. Reset by unplugging and reconnecting the charger.
• 4 RED BLINKING LEDS: Internal Over-temp Shutdown
  The charger shuts down if internal temperatures exceed specified levels. Allow the unit to cool and reset.
• 5 RED BLINKING LEDS: Overvoltage Protection
  This indicates a possible output defect. Discontinue use and contact technical support.

B. For legacy PS and SS Marine chargers the flashing light sequences indicate the following:

• 30% LED indicator flashing. No battery detected, check the connections for proper polarity (black wire to negative).
• 30 AND 50% LED indicators flashing.  This indicates a Forming Stage timeout and
  alerts the user that the battery voltage has not risen above an acceptable
  limit within 3 hours.  Battery should be tested. 
• 30, 50 and 90% LED indicators flashing.  This indicates that the
  charger has exceeded the maximum amount of time allowed for charging the battery.  Battery should be tested.  
• 30 and 90% LED indicators flashing. This indicates that the internal temperature of the charger has exceeded allowable limits and this bank of the charger has shut down.  If charger is in a closed compartment, open compartment doors and allow charger to cool for 8 hours.  After this period, connect the charger to AC and begin charging again. 

C. For Auto Profile PS and SS chargers:

• 30% LED indicator flashing. No battery detected, check the connections for proper polarity (black wire to negative).
• 30 AND 50% LED indicators flashing.  This indicates a Forming Stage timeout and
  alerts the user that the battery voltage has not risen above an acceptable
  limit within 3 hours.  Battery should be tested. 
• 30, 50 and 90% LED indicators flashing.  This indicates that the
  charger has exceeded the maximum amount of time allowed for charging the battery.  Battery should be tested.  
• 30 and 90% LED indicators flashing. This indicates that the internal temperature of the charger has exceeded allowable limits and this bank of the charger has shut down.  If charger is in a closed compartment, open compartment doors and allow charger to cool for 8 hours.  After this period, connect the charger to AC and begin charging again. 
• 70% solid, 90%, and 100% LED’s continually scrolling. This indicates a period in which the charger bank has shut off charging current to allow firmware to analyze the battery immediately after initial charging has been accomplished.
• 90% solid with 100% LED blinking. This indicates a period in which the charger bank has confirmed successful initial charging and is monitoring and analyzing the battery to determine whether a Lithium, AGM, or FLA battery is connected.  At the completion of this portion, additional charging might occur with a solid 100% LED for AGM batteries if required.
