Sony DCR-TRV900 Manual

Charging the vanadium-lithium battery in the
camcorder

Your camcorder is supplied with a vanadium-lithium battery installed so as to retain the
date and time, etc., regardless of the setting of the POWER switch. The vanadium-lithium
battery is always charged as long as you are using the camcorder. The battery, however, will
get discharged gradually if you do not use the camcorder. It will be completely discharged
in about a year if you do not use the camcorder at all. Even if the vanadium-lithium battery
is not charged, it will not affect the camcorder operation. To retain the date and time, etc.,
charge the battery if the battery is discharged. The following are charging methods:
• Connect the camcorder to house current using the supplied AC power adaptor, and leave

the camcorder with the POWER switch turned off for more than 24 hours.

• Or install the fully charged battery pack in the camcorder, and leave the camcorder with

the POWER switch turned off for more than 24 hours.
