At the time of purchase, or when the Nickel Metal Hydride
batteries haven’t been used for a long time, they may not
fully charge. This is typical of this type of battery, and is not
a malfunction. If this happens, several cycles of using the
battery until it is completely drained and then charging the
battery fully should correct the problem.

If you recharge Nickel Metal Hydride batteries before fully
using up the existing charge, the low battery warning may be
displayed sooner than expected. This is called the “memory
effect.”* If this problem occurs, charging the batteries only
after using up the existing charge will correct it.

Precautions to be observed when
charging the batteries

•
Do not charge any other batteries except Sony Nickel Metal
Hydride batteries in the charger supplied with your camera.
If you try to charge any other type of battery (e.g.,
manganese batteries, alkaline dry cells, or primary lithium
batteries) than the batteries specified, those batteries may
leak, overheat, or explode, causing the danger of burns or
other injuries.
