The battery life values listed in this Help Guide are measured values acquired under our measurement conditions and may shorten depending on the usage of your IC recorder.

Your IC recorder still consumes slight battery power while no operations are in progress. If you do not intend to use the IC recorder for an extended period of time, it is recommended that you turn the power off. It is also recommended that you set [Auto Power Off] to a shorter period of time. This will help you save battery power in case you forget to turn off the power of the IC recorder.

When you start charging the built-in rechargeable battery of your IC recorder, the battery indicator appears quickly on the display window. However, this does not indicate that the battery is fully charged. When the battery is running out of power, it takes about 1 hour to fully charge the battery.

When you have not used your IC recorder for an extended period of time, repeat charging and discharging (by operating the IC recorder) for several times.

You are using your IC recorder under the temperature of 5 °C (41 °F) or below where the battery wears quickly. This is due to the characteristics of the battery and does not indicate a malfunction.

The built-in rechargeable battery is deteriorated.

The rechargeable battery is capable of charging about 500 times but the rechargeable times vary depending on the usage of your IC recorder. If the fully charged battery wears out in half the time it normally does, it indicates that the battery is deteriorated. Consult your nearest Sony dealer.
