Battery Care

Precautions for Use
●
•
If improperly handled, batteries may rupture or leak, causing the
product to corrode. Observe the following precautions when handling
batteries:
- Turn the product off before replacing the battery.
- Batteries may be hot after extended use.
- Keep the battery terminals clean.
- Use only batteries approved for use in this equipment.
- Do not short or disassemble batteries or expose them to flame or
excessive heat.
- Replace the terminal cover when the battery is not inserted in the
camera or charger.
•
If the battery is hot, for example immediately after use, wait for it to cool
before charging. Attempting to charge the battery while its internal
temperature is elevated will impair battery performance, and the
battery may not charge or charge only partially.
•
If the battery will not be used for some time, insert it in the camera and
run it flat before removing it from the camera for storage. The battery
should be stored in a cool location with an ambient temperature of
15 °C to 25 °C (59 °F to 77 °F). Avoid hot or extremely cold locations.
•
Batteries should be charged within six months of use. During long
periods of disuse, charge the battery and use the camera to run it flat
once every six months before returning it to a cool location for storage.
