Standby battery for Volvo On Call*

If the main battery is de-energised then the standby battery for Volvo On Call is used as backup battery so that the system can still be used.

The standby battery has a limited service life. When the battery needs service or replacement, a message, Volvo On Call Service required, is shown in the driver display.

If the message remains, contact an authorised Volvo workshop.
