memory effect

Ni-Cd batteries, and to some lesser degree Ni-MH batteries, endure from what's named the "memory effect". What this suggests is the simple fact that if a battery is repeatedly only partially discharged prior to recharging, the battery "forgets" that it has the ability to even more discharge all of the way down.

To illustrate: If you, on the normal basis, completely demand your battery after which use only 50% of its ability prior to the subsequent recharge, ultimately the battery will grow to be unaware of its added 50% ability which has remained unused. The battery will stay functional, but only at 50% of its authentic capacity.

The method to keep away from the dreaded "memory effect" would be to completely cycle (fully demand after which completely discharge) the battery at the very least as quickly as each two to 3 weeks. Batteries may be discharged by unplugging the device's AC adapter and letting the unit operate for the battery till it ceases to function. this can make sure your battery continues to be healthy.
