The slow flash should stop after a short while or after the temperature returns to a suitable range between 50☏ and 86☏ (10☌ and 30☌).įast flashing indicates a poor connection between the battery and charger or a problem with the battery pack. Slow flashing occurs if the battery has not been charged for a long time or if the environmental temperature is not suitable for charging the battery. The CHARGE lamp may flash fast (multiple times a second) or slow (around 1.5 second intervals), depending on the cause.
There is a poor connection between the battery and charger.The battery pack has not been used for a long time.The environmental temperature is too cold to charge the battery pack.Remove at least one of the batteries and the light will go off.The CHARGE light may flash for the following reasons:
The red light remains on when the charger is unplugged. Leave the batteries in the charger, while the light continues to blink red, for about 24 hours. If the light blinks red in about 90 seconds after battery insertion, then the battery voltage is too low. If charging is needed, briefly drain the batteries before trying again. This indicates that the battery already have a full charge. There are several ways to restore batteries that cannot be charged by the charger.If the light blinks red within five seconds after battery insertion, then the battery voltage is too high. Occasionally, the charger might show blinking red right to indicate bad batteries.
Rescuing “bad batteries” indicated by a blinking red light. The charger has a built-in converter circuitry that will become warm during rapid charging. It is normal for the charger to become warm while rapid charging. This does not mean the batteries are charged faster than others or overcharged The two batteries will become warmer than the other batteries due to heat generated by a converter circuitry in the charger. It is normal for the two rear batteries to become warmer than the other banks.
