Lithium Battery Replacement

The lithium battery lasts about two years with normal use.* When the battery is depleted, the data and time settings are lost. Contact your Sony Service Center to have the battery replaced (for a charge).

*Presuming the power is normally kept on. If the power is regularly turned off, battery life can be expected to be about one year. Actual battery life depends on the operating conditions.
