7.2v Robot Battery

From VEX Wiki

VEX Battery Packs are the recommended power source option for the VEX Robotics Design System. These batteries are designed to handle the large current draw typically associated with VEX robots. They 7.2v Robot Battery is NiCd rechargeable. It is plugged directly into the VEX Microcontroller.

The robot battery pack contains NiCd (Nickel-Cadmium chemical composition) rechargeables that provide significantly more energy than comparable AA NiCd batteries. The Battery Pack’s cells will provide a constant reliable voltage until they are exhausted. Contrary to popular belief, NiCd batteries do not suffer from any sort of permanent “memory effect” .

Rechargeable NiCd batteries can be used over and over again for hundreds of battery cycles if properly maintained. However, all batteries will eventually wear out over time. If you notice an old set of batteries is not performing as well as it used to, it may be time to get a fresh set.

The cadmium found in NiCd batteries is highly toxic, and should not be disposed of in the trash. It is illegal to do so in many countries and states. Check your local regulations for information on proper battery recycling procedures in your area.
