Normal 

charging time

(Approx.)

250 min

For more about the battery life, see the instruction manual of your 

camera.

The charging time may differ depending on the condition of the battery 

pack or the ambient temperature.

The times shown are for charging an empty battery pack, which 

has been run down with a camera, using this unit at an ambient 

temperature of 25 °C (77 °F).

The temperature range for charging is 0 °C to 40 °C (32 °F to 104 °F).  

For maximum battery efficiency, the recommended temperature 

range when charging is 10 °C to 30 °C (50 °F to 86 °F).

You can remove the battery pack from this unit and use it even if 

charging is not completed. However, the charging time affects the time 

that the battery pack can be used.

If the CHARGE lamp does not light up, check if the battery pack is 

firmly attached to this unit.

When a fully charged battery pack is installed, the CHARGE lamp 

lights up once and then goes out.

A battery pack that has not been used for a long time may take longer 

than usual to charge.

You can use the battery charger in any country/region where the 

power supply is from 100 V to 240 V AC, 50 Hz/60 Hz.

Do not connect this unit to a voltage adaptor (travel converter) 

for overseas travel. This may result in overheating or another 

malfunction. 

When the CHARGE lamp blinks, check through the following chart.

When charging a battery pack that has not been used for a long time, the 

CHARGE lamp may blink in some rare cases.

If this happens, remove the battery pack from this unit and then attach 

and charge it again.
The CHARGE lamp blinks in two ways.

Blinks slowly:  Turns on and off repeatedly every 1.5 seconds

Blinks quickly: Turns on and off repeatedly every 0.15 seconds

The action to be taken depends on the way the CHARGE lamp blinks.
When the CHARGE lamp keeps blinking slowly

Charging is pausing. This unit is in the standby state.

If the room temperature is out of the appropriate temperature range, 

charging stops automatically.

When the room temperature returns to the appropriate range, the 

CHARGE lamp lights up and charging restarts.

We recommend charging the battery pack at 10 °C to 30 °C (50 °F to  

86 °F).
When the CHARGE lamp keeps blinking quickly

Check through the following chart.

Please contact your nearest Sony dealer in connection with the product that may

Remove the battery pack that is being charged and then firmly attach the same 

battery pack again.

The problem is with this unit.
