866 Caring for the Camera and Battery: Cautions
Cautions: Using Batteries
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, remove it from the camera
and store it in a cool, dry 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 once every six months before returning it to a
cool location for storage.
• Remove the battery from the camera or charger when not in use. The
camera and charger draw minute amounts of charge even when off and
could draw the battery down to the point that it will no longer function.
