Tips for using the
rechargeable lithium
ion battery
On charging
Recharge the battery whenever you
like
You do not have to discharge it before
recharging.
Recharge the battery before use.
The battery is always discharging even
when it is not in use after charging.
Therefore, you should charge the
battery right before using the camera.
On recording with batteries
Have sufficient battery power to do
2 to 3 times as much recording as
you have planned.
On battery life
Battery life is shorter in a cold
environment
Battery efficiency is decreased, and the
battery is used up more cpoickly, if you
are recording in a cold environment
(lower than 50° F (10° C)). To make the
battery life longer, it is recommended
to tty the following:
• Keep the battery warm in a pocket,
etc., and install it right before using
the camera. When using a body
warmer, be careful the warmer does
not touch the battery.
• Charge the battery as follows: Install
the battery into the camera and
connect the AC power adapter to
the camera and a wall outlet.
You should charge the battery at
temperatures from 50 °F to 86°F
(from 10 C° to 30° C). Lower
temperatures require a longer
charging time.
