Preventing “Memory Effect” in your Batteries

How to increase battery life – although this article is written for radio and mobile terminal users, the information in this article may be useful for anyone who utilizes technology with rechargeable batteries.
If you use a two-way radio or a hand-held mobile terminal you probably have experienced a problem with batteries suddenly losing their ability to maintain a charge. This is especially true if you use Nickel-Cadmium (NiCad) or Nickel-Metal-Hydride (NiMH) batteries.
This phenomenon is called “memory effect” and it can quickly develop when the battery is not completely discharged prior to being charged again. When the battery has repeated shallow discharges, only a small portion of the battery chemicals are exercised, and in effect, this causes the battery voltage to drop. The net effect is ownership of a perfectly good battery that no longer holds a decent charge.
