Tips for Using the Battery and Charger
Upon purchase, the battery is not fully charged.
Charge the battery before use.
Recharge the battery on the day before or on the day it is to be used.
Even during storage, a charged battery will gradually drain and lose its capacity.
After recharging the battery, detach it and disconnect the
charger from the power outlet.
You can attach the cover in a different
orientation to indicate whether the battery
is recharged or not.
If the battery is recharged, attach the cover so that the battery-
shaped hole <
the battery is exhausted, attach the cover in the opposite orientation.
When not using the camera, remove the battery.
If the battery is left in the camera for a prolonged period, a small
amount of power current will continue to be released, resulting in
excess discharge and shorter battery life. Store the battery with the
protective cover attached. Storing the battery when it is fully charged
may lower the battery performance.
The battery charger can also be used in foreign countries.
The battery charger is compatible with a 100 V AC to 240 V AC 50/60 Hz
power source. If necessary, attach a commercially-available plug adapter for
the respective country or region. Do not attach any portable voltage
transformer to the battery charger. Doing so may damage the battery charger.
If the battery becomes exhausted quickly even after having been
fully charged, the battery has reached the end of its service life.
Check the battery's recharge performance and purchase a new battery.
After disconnecting the charger's power plug, do not touch the prongs for
approx. 10 sec.
If the battery's remaining capacity is 94% or higher, the battery will not be
recharged.
The provided charger cannot charge any battery other than Battery Pack
LP-E6N/LP-E6.
