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 in long-term storage should be charged to about 50% at least once a year. Do not
charge the battery to 100% before returning it to storage. A fully-exhausted battery will charge
to around 50% in about half the time needed to charge it to 100%.
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.
Do not use the battery at ambient temperatures below −10 °C (14 °F) or above 40 °C (104 °F).
Failure to observe this precaution could damage the battery or impair its performance. Charge
the battery indoors at ambient temperatures of 5 °C–35 °C (41 °F–95 °F). The battery will not
charge if its temperature is below 0 °C (32 °F) or above 60 °C (140 °F).
Capacity may be reduced and charging times increase at battery temperatures from 0 °C (32 °F)
to 15 °C (59 °F) and from 45 °C (113 °F) to 60 °C (140 °F).
Batteries in general exhibit a drop in capacity at low ambient temperatures. Even fresh batteries
charged at temperatures under about 5 °C (41 °F) may show a temporary increase from "0" to
"1" in the setup menu [Battery info] age display, but the display will return to normal once the
battery has been recharged at a temperature of about 20 °C (68 °F) or higher.
Battery capacity drops at low temperatures. The change in capacity with temperature is reflected
in the camera battery-level display. As a result, the battery display may show a drop in capacity as
the temperature drops, even if the battery is fully charged.
Batteries may be hot after use. Observe due caution when removing batteries from the camera.
