Extending Life of Rechargeable Batteries

In a new nickel cadmium battery, the active materials consist of finely divided crystals. Over time, the crystal size grows and the charge acceptance (capacity) drops. Applying a periodic full discharge reverses this condition, also known as "memory". In advanced stages, reconditioning is necessary.

Does the green light on the charger indicate a good battery?
No. Even a low performing battery will show "ready" when full and weak Batteries go to ready quicker than good packs. Properly maintained batteries assure the packs perform at the required capacity level.

How often should a battery be serviced?
The recommended interval is once every 1-2 months for nickel cadmium and once every 3 months for nickel metal hydride.

Can older batteries be restored?
Between 50-70% of discarded nicad packs can be restored when properly reconditioned with a programmable battery analyzer.
