4-Volt replacement battery for the Volvo On Call unit. Specifically designed as an improved direct replacement for the original battery.
The message "On Call Service required" usually means that the backup battery in the Volvo On Call system has degraded.
This is a common issue on Volvo models equipped with VOC, where the backup battery for the telematics module typically reaches the end of its lifespan after around 10 years.
At Volvo, a battery replacement can cost around 4600 SEK, making this aftermarket battery a much more cost-effective solution if you don’t mind doing the replacement yourself.
