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.
• 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). Efficient charging may not be possible
outside this range.
• 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.
Charging time
This represents the time required to charge fully
depleted Nickel Metal Hydride batteries using the
supplied BC-CS1 charger in an environment where the
ambient temperature is 25°C (77°F).
• It takes about 13 hours to completely charge the batteries.
The CHARGE lamp may remain lit longer than 13 hours, but
this is not a malfunction.
• Do not remove the batteries while charging is still in
progress. If the power supply is interrupted by a power
failure or other reason either during charging or after
charging has finished, charging starts over and the batteries
are charged again for approximately 13 hours.
• If you use the ACC-UNQ STAMINA “Super Quick charge”
kit (not supplied), the batteries will charge faster.
