324 Technical Notes
Caring for the Battery
Batteries may leak or explode if improperly handled. Observe the
following precautions when handling batteries:
• Use only batteries approved for use in this equipment.
• Do not expose the battery to flame or excessive heat.
• Keep the battery terminals clean.
• Turn the product off before replacing the battery.
• Remove the battery from the camera or charger when not in use and
replace the terminal cover. These devices draw minute amounts of
charge even when off and could draw the battery down to the point
that it will no longer function. If the battery will not be used for some
time, insert it in the camera and run it flat before removing it and
storing it in a location with an ambient temperature of 15 °C to 25 °C
(59 °F to 77 °F; avoid hot or extremely cold locations). Repeat this
process at least once every six months.
• Turning the camera on and off repeatedly when the battery is fully
discharged will shorten battery life. Batteries that have been fully
discharged must be charged before use.
• The internal temperature of the battery may rise while the battery is in
use. Attempting to charge the battery while the internal temperature
is elevated will impair battery performance, and the battery may not
charge or charge only partially. Wait for the battery to cool before
charging.
• Continuing to charge the battery after it is fully charged can impair
battery performance.
