Baery pack or charging fault

Battery Pack or Charging Faults and Remedies

Possible causes for a ashing red LED:

Over-discharged baery: The baery pack is severely

depleted. The red LED ashes a few seconds aer the baery

is inserted. If the red LED continues to ash for a couple

of minutes, remove the baery pack. It might be faulty,

requiring replacement.

Pre-charge time out: A low baery pack is inserted and

the voltage does not reach an acceptable charge level. The

red LED ashes 30 minutes into the charge. The baery

pack might be at the end of its life or faulty, requiring

replacement. Note: Do not confuse this with the out-of-

temperature fault (next case).

Out-of-temperature range for safe charging: The charger

senses the baery pack is too cold (< 0˚ C, 32˚ F) or too hot

(> 40˚ C, 104˚ F) for safe charging. This can occur at any

time in the charge cycle. The red LED continues to ash,

even aer the baery pack is removed. Reset the charger by

inserting a baery pack with an acceptable temperature or

remove and reapply the external power to the charger. Bring

the temperature of the baery pack into the safe charging

range. If the problem persists, the baery pack might be

faulty, requiring replacement.

Charge cycle time out: The baery pack does not reach full

charge within eight hours. The baery pack might be at the

end of its life or faulty, requiring replacement.
