Fast Chargers Rapidly Charge Batteries
What a fast chargers does, is to use the control circuitry in the battery in order to rapidly charge the battery without damaging the cells’ elements. Most of these chargers have a fan to help dissipate the heat and keep it under control. Most of these charges have the dual capability of overnight charging NiMH batteries that don’t have the control circuit built in. There are a few chargers coming onto the market than can fast-charge the NiMH batteries that do not have the control circuit.
