Lithium batteries
Manganese batteries
Ni-Cd batteries
* Before using batteries, read the following precaution for each type of battery.
Nickel-Metal Hydride batteries can be charged using a battery charger (sold
separately).
As for unsupported batteries, operating performance cannot be ensured if
voltage drops or other problems are caused by the nature of the battery.
On alkaline batteries (supplied)
Alkaline batteries cannot be recharged.
Alkaline batteries have a shorter life compared to the Nickel-Metal Hydride
batteries. For this reason, the power may turn off even though the remaining
charge indicator shows sufficient battery life remaining.
Battery performance differs greatly depending on the manufacturer and the type
of battery, and in some cases the battery life may be significantly shorter. This is
especially true at low temperatures, and you may not be able to shoot at
temperatures below 5°C (41°F).
Do not mix new and old batteries.
The remaining charge indicator may not display the correct information when
using alkaline batteries.
Due to characteristics of alkaline batteries, there is a large difference between
the available shooting time and the available playback time. For this reason, the
camera may turn off with the lens portion extended when you change the
shooting mode. In this case, replace the batteries with new ones. Using the
Nickel-Metal Hydride batteries allows you to shoot for longer periods of time.
On Nickel-Metal Hydride batteries (sold separately)
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. These may cause leakage, explosion, or heat-up of
the battery, and personal scald or injury may be caused. These may cause a
malfunction of the battery charger.
Do not carry or store the Nickel-Metal Hydride batteries with metallic objects.
Metallic objects may short the + and – ends, resulting in the risk of heating or
fire.
If the poles of the Nickel-Metal Hydride batteries are dirty, the batteries may not
charge properly. Wipe them with a dry cloth, etc.
At the time of purchase, or when the Nickel-Metal Hydride batteries have not
been used for a long time, they may not charge fully. This is typical of this type of
battery, and is not a malfunction. If this happens, repeatedly using up the
batteries fully, and then recharging them should correct the problem.
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.
