. Using Rechargeable Batteries
In the case of rechargeable batteries, use of one of the rechargeable Ni-MH (nickel
metal hydride) batteries (HR6) listed below is recommended.
SANYO eneloop (SANYO Electric Co., Ltd.)
DURACELL RECHARGEABLE (DURACELL, div of P&G Inc.)
ENERGIZER RECHARGEABLE (Energizer Holdings, Inc.)
IMPORTANT!
Never mix four batteries of different brands, ages, or charge levels. Doing so
creates the risk of shortened battery life and can even damage the camera.
Batteries cannot be recharged while they are loaded in the camera.
. Refreshing Rechargeable Batteries
Batteries can start to lose their ability to retain a charge if you do not use them for a
long time or when you charge them repeatedly without allowing their current charge
to be used up completely. If this happens, you may be able to restore battery capacity
by performing the following “battery refresh” operation to fully discharge the batteries.
1. Load the chargeable batteries into the camera.
2. While holding down [MENU], press the power button. This should cause the
firmware version screen to flash on the monitor screen.
3. Leave the camera on until the batteries run out of power and the camera turns off.
The battery refresh operation can take as long as 10 hours. The actual amount
of time required depends on battery conditions.
4. After the camera turns off, remove the batteries and charge them.
IMPORTANT!
Performing the battery refresh operation reduces the battery charge level to almost
zero. Never load refreshed batteries into the camera without charging them first.
Though you may be able to momentarily turn on the camera while refreshed
uncharged batteries are loaded, power may suddenly fail, leaving the lens
extended, or some other misoperation may occur.
You do not need to perform the above operation each time you charge the
batteries. Only use it if you notice that you are getting less operation between
charges. Note that you may eventually reach the point when even the above
operation will not refresh batteries. If this happens, it means that the rechargeable
batteries have reached the end of their service life and that you will need to
purchase new rechargeable batteries.
The above notes are all based on use of a recommended type of rechargeable
Ni-MH battery.
