Using the AA-size Ni-MH batteries correctly

•As a power source in digital cameras, AA-size Ni-MH batteries (referred to hereafter as Ni-MH batteries) are superior to alkaline batteries in several ways, such as allowing more shots to be taken with the camera.

However, care must be taken with the way Ni-MH batteries are used if their original performance is to be maintained.

•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.

Deactivation and memory are specific to Ni-MH batteries and are not in fact battery faults. See p.146- 147 for the procedure for “Discharging rechargeable batteries”.

CAUTION

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

•To charge Ni-MH batteries, use the quick battery charger (sold separately). Refer to the instructions supplied with the charger to make sure that the charger is used correctly.

•Do not use the battery charger to charge other batteries.•Note that the batteries feel warm after being charged.

•Due to the way the camera is constructed, a small amount of current is used even when the camera is turned off. Note in particular that leaving Ni-MH batteries in the camera for a long period will overdischarge the batteries and may render them unusable even after recharging.

•Ni-MH batteries will self-discharge even when not used, and the time for which they can be used may be shortened as a result.

•Ni-MH batteries will deteriorate rapidly if overdischarged (e.g. by discharging the batteries in a flashlight). Use the “Discharging rechargeable batteries” function provided in the camera to discharge the batteries.

•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.

ZDisposing of Batteries

When disposing of batteries, do so in accordance with your local waste disposal regulations.
