Battery "memory Effect"

What is the "Memory Effect" that I have heard about?
NiCad batteries, and to a lesser extent NiMH batteries,
. . . suffer from what's called the "memory effect".
What this means is that if a battery is repeatedly only partially discharged,
. . . before recharging,
. . . the battery "forgets" that it has the capacity to further discharge all the way down.
To illustrate: If you, on a regular basis, fully charge your battery, and
. . . then use only 50% of its capacity before the next recharge,
. . . eventually the battery will become unaware of its extra 50% capacity
. . . which has remained unused.
The battery will remain functional,
. . . but only at 50% of its original capacity.
The way to avoid the dreaded "memory effect,"
. . . is to fully cycle (fully charge and then fully discharge) the battery,
. . . at least once every 2-3 weeks.
Batteries can be discharged by unplugging the device's AC adapter, and
. . . letting the device run on the battery until it ceases to function.
. . . This will insure your battery remains healthy.
