BATTERY MEMORY EFFECT 

Battery Memory Effect Problems NiCad and to a much smaller degree NiMH batteries, can be affected by a "memory effect" problem. A memory effect problem can occur when a battery is repeatedly only partially discharged before it is recharged - the battery forgets that it has the capacity to discharge all the way down. This problem is caused by an accumulation of gas bubbles on the batteries cell plates when the battery is only partially discharged and then recharged. The gas bubbles reduce the cell plates surface area - resulting in a decrease in capacity. For example: If a battery is 100% fully charged and then uses only 40% of its capacity before the next recharge, after time the battery will become unaware of its extra 60% capacity which has remained unused. The battery will remain functional, but only at 40% of its capacity. To avoid this "memory" problem be sure to fully cycle (fully charge and then fully discharge) the battery at least once every few weeks. A batteries can be discharged by unplugging the devices AC adapter and letting the device run on the battery until it stops functioning - this will ensure the battery remains in good condition.
