CHARGING THE BATTERY
battery tends to discharge if not used for an extended period of time. If the battery is stored for
a extended length of time without being recharged, you may not be able to recharge it.
• A battery charged after being stored for a long period may not supply power for the specified
time. Additional rechargings will help restore the battery's operation time.
• The battery should be charged at a temperature of 50ºF - 86ºF (10ºC - 30ºC) to prevent
damage.
• Do not operate the battery at temperatures below 14ºF (-10ºC) or above 95ºF (35ºC). The
battery may be damaged if operated at temperatures above 122ºF (50ºC). Operation time will
decrease at extremely low temperatures.
• After repeated chargings and use, the operation time will gradually decrease. When operation
time becomes too short to be useful, it is time to replace the battery.
• If the "CHARGE" light on the AC adaptor/charger starts flashing, remove the battery and
then reattach it. If after several attempts the light continues to flash, this means your battery
cannot take a charge and must be replaced with a new one.
The "CHARGE" light will not light if a hot battery is attached to the AC adaptor/charger.
Attaching an extremely hot battery to the AC adaptor/ charger is not recommended; it should
be allowed to cool down before being attached.
• Do not short the battery's terminal.
• Do not attempt to disassemble or modify the battery. There are no user serviceable parts
inside.
• Throwing the battery into a fire or exposing the battery to excessive heat - over 149ºF (65ºC)
could be hazardous.
• Be sure to set "CAM/OFF/VIDEO" to the position before removing the battery.
