The Chargers are available to recharge the batteries. The NiCd and NiMh batteries share most of the chargers with full compatibilty. But, the Lithium LiFePo4 batteries must use the special Lithium Charger so these have a special charge plug to prevent you from making a mistake.
All of our current chargers are international voltage compatible, it was not always that way so be aware if using outside them of America.
The Chargers that we offer today are made for the modern batteries built since 2002 with serial numbers higher than 149300. The batteries made before that time may not stop charging correctly with a modern style charger. Contact Lumedyne directly if you have Classic Batteries with lower serial numbers than that.
