Fast Battery Charger

From VEX Wiki

The VEX Quick Charger has the ability to charge both 7.2V Robot Battery Packs & 9.6V Transmitter Battery Packs. There are two tabs inside each charging socket which trigger if the larger 7.2V pack is inserted. When these tabs are triggered, the charger will switch to a 7.2V charge rate, otherwise it will charge at a 9.6V rate.

As with all NiCd batteries you should avoid overcharging them. Overcharging can cause permanent damage to the battery. The VEX Fast Charger knows when to stop adding charge to the batteries. Once the battery has reached full charge, the charger will switch over into “trickle charge” mode, which is a low current mode that can be safely applied over a long period of time to maintain a full charge.
