When charging a fully depleted battery pack at a temperature of 25°C (77°F).
The CHARGE lamp
(A) turns off when charging is completed.
Note
The charging time differs depending on the remaining charge of the battery pack and on the charging
conditions.
Be sure to use only genuine Sony brand battery packs.
We recommend charging the battery pack at an ambient temperature of between 10°C to 30°C (50°F
to 86°F). You may not be able to efficiently charge the battery pack outside this temperature range.
Connect the battery charger to the nearest wall outlet (wall socket). If malfunctions occur while using
the charger, disconnect the plug from the wall outlet (wall socket) immediately to disconnect from the
power source.
Even when the CHARGE lamp of this battery charger is off, the power is not disconnected. If any
trouble occurs while this unit is in use, unplug it from the wall outlet (wall socket) to disconnect the
power.
When the camera is being used for the first time or when you use a battery pack that has not been
used for a long time, the CHARGE lamp may flash quickly when the battery is charged for the first
time. If this happens, remove the battery pack from the charger and then re-insert it to recharge.
Do not continuously or repeatedly charge the battery pack without using it if it is already fully charged
or close to fully charged. Doing so may cause a deterioration in battery performance.
