Procedure for discharging rechargeable Ni-MH batteries

h AA-size alkaline batteries (2), Rechargeable Battery NH-10 (Sold separately), or optional AA-

size Ni-MH batteries (2).

●

We recommend that the AA-size alkaline batteries used be the same brand as those supplied with the camera.

Only use the “Discharging rechargeable batteries” function with Ni-MH
batteries (rechargeable batteries).
The “Discharging rechargeable batteries” function should not be used with
alkaline batteries as it will completely drain the battery charge.

Use the “Discharging rechargeable batteries” function in the following situations:
i When the batteries can only be used for a short time after being charged normally
i When the batteries have not been used for a long period
i When you purchase new Ni-MH batteries
Do not use the “Discharging rechargeable batteries” function when the camera is set in the
cradle or when you are using the AC power adapter. In these situations, the Ni-MH batteries will
not be discharged due to the external power supply.

How to use the battery

◆

h Never use the following types of battery, as this could cause serious

problems such as battery fluid leakage or overheating:
1. Batteries with split or peeling outer casings
2. Combinations of different types of batteries or new and used batteries

together

h Do not use lithium, manganese or Ni-Cd batteries.
h Soiling such as fingermarks on the poles of the batteries can significantly reduce the amount of

time for which the batteries can be used.

h The time for which AA-size alkaline batteries (referred to hereafter simply as alkaline batteries)

can be used varies depending on the brand, and some alkaline batteries may stop providing
power more quickly than those supplied with the camera. Note also that due to their nature, the
time for which alkaline batteries can be used decreases in cold conditions (0°C to 10°C). The use
of AA-size Ni-MH batteries is recommended for this reason.

h See P.72, 73 for other notes on using batteries.

AA-size Ni-MH batteries and the Rechargeable Battery NH-10

◆

h When used as a power source for a digital camera, AA-size Ni-MH batteries and the

Rechargeable Battery NH-10 (referred to hereafter as Ni-MH batteries) are superior to alkaline
batteries in that they allow more shots to be taken. However, to retain the original performance
characteristics of Ni-MH batteries, care must be taken in the way they are used.

h Ni-MH batteries left unused in storage for long periods can become “deactivated”. Also,

repeatedly charging Ni-MH batteries that are only partially discharged can cause them to suffer
from the “memory effect”.
Ni-MH batteries that are “deactivated” or affected by “memory” suffer from the problem of only
providing power for a short time after being charged. To prevent this problem, discharge and
recharge them several times using the camera’s “Discharging rechargeable batteries” function. By
repeating this cycle several times, the temporary reduction in performance caused by “memory” or
“deactivation” can be remedied and the batteries can be restored to their original performance
levels.
See P.11 for the procedure for “Discharging rechargeable batteries”.
Deactivation and memory are specific to Ni-MH batteries and are not in fact battery faults.

●

Do not use the “Discharging rechargeable batteries” function when alkaline batteries are
being used.

●

Ni-MH batteries will deteriorate rapidly if overdischarged. Use the “Discharging rechargeable batteries” function
provided in the camera to discharge batteries. Discharging batteries such as in a flashlight can result in impaired
battery performance because of overdischarging.

●

The rechargeable battery NH-10 can be charged by setting the camera in the PictureCradle CP-FXA10 (optional).
Use AC power adapter AC-3VW which is enclosed with PictureCradle for charging NH-10. Commercially
available Ni-MH batteries can not be charged in the Picture Cradle.
Use the optional charger to charge AA-size Ni-MH batteries.

●

Ni-MH batteries are not fully charged when purchased. They may also be “deactivated”. Accordingly, you should
discharge them once using the camera's “Discharging rechargeable batteries” function, and then charge them
fully again before using them in the camera.

●

Ni-MH batteries have a limited service life. If a battery can only be used for a short time even after repeated
discharge-charge cycles, it may have reached the end of its service life.

●

When using the “Discharging rechargeable batteries” function, do not connect the AC power adapter to the
camera or set the camera in the cradle.
