Choosing the right charger is very easy - just enter an exact drill model in our search engine. Just make sure your batteries have the cells supported by the charger. Many older power tools have a battery with nickel-cadmium (NI-Cd) cells. Today, Nickel-Metal Hydride (NI-MH) batteries are more commonly used, and chargers compatible with these batteries can properly operate older devices. We also offer Lithium Ion (LI-ON) cell chargers - these are only suitable for this type of cell and should not be used to charge NI-MH or NI-CD batteries.
