Charging the Nickel Metal Hydride
batteries
• If the poles of the Nickel Metal Hydride batteries are dirty,
the batteries may not charge properly. Occasionally clean
the poles of the batteries and the terminals of the charger
by wiping them with a dry cloth.
• 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.
• Even when Nickel Metal Hydride batteries are not being
used they lose their charge naturally over time. It is
recommended that you recharge the batteries just before
using them.
• 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.
* The “memory effect” – the situation in which the
capacity of the battery is temporarily lowered.
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 one-time
lithium batteries) than the batteries specified, those
batteries may leak, overheat, or explode, causing the
danger of burns or other injuries.
• Be sure to charge both Nickel Metal Hydride batteries at
the same time.
• When the batteries are charged, use them only in an
environment where the temperature range is 10°C to 30°C
(50°F to 86°F). Otherwise, there is a danger of leaks,
explosions, excessive heat, fire, or electric shock.
• Do not charge fully charged Nickel Metal Hydride
batteries again. Otherwise, there is a danger of leaks,
explosions, excessive heat, fire, or electric shock.
• Do not peel off the external seals or damage the batteries.
Never use batteries from which the seals have been
partially or completely removed, or batteries that have
been split in any way.
