The Volvo GBQ6E BP15 (often associated with part number 31450445) is a specialized backup battery critical to the modern Volvo ecosystem. Unlike standard automotive starter batteries, this compact unit is designed to power the Vehicle Connectivity Module (VCM), ensuring that essential safety and communication features remain operational even if the primary power source fails.
Function and Importance
The primary role of the GBQ6E BP15 is to support the Volvo On Call system and the vehicle’s emergency assistance features. In the event of a serious collision where the main car battery might be disconnected or damaged, this backup battery provides the necessary energy to:
- Automatically trigger emergency “SOS” calls.
- Transmit the vehicle’s precise GPS coordinates to rescue services.
- Maintain the gateway for remote vehicle diagnostics and smartphone app connectivity.
Technical Specifications
While slight variations exist between OEM and aftermarket versions, the core specifications typically remain within the following parameters:
- Part Number: 31450445 / GBQ6E BP15
- Battery Type: Lithium-ion (Li-ion)
- Voltage: Usually rated at 7.2V to 8.0V
- Capacity: Ranges between 450mAh (3.24Wh) and 750mAh

Applicable Models
This battery is widely used across Volvo’s SPA (Scalable Product Architecture) and CMA (Compact Modular Architecture) platforms. It is generally found in vehicles produced from 2017 to 2026. Compatible models include:
- Sedans: S60 (MK3), S90
- SUVs: XC40, XC60 (2nd Gen), XC90 (2nd Gen)
- Wagons/Crossovers: V60 (2nd Gen), V90, V90 Cross Country

Maintenance and Replacement
Volvo owners typically become aware of this battery when a “Telematics Service Required” or “Volvo On Call Service Required” message appears on the driver display. Because the GBQ6E BP15 is a rechargeable Li-ion cell, its capacity naturally degrades over several years due to heat and cycle aging.
When replacing the unit, it is vital to ensure the connector pins match the vehicle’s gateway module, as the VCM is a sensitive component of the car’s internal network. Proper replacement ensures that the vehicle remains compliant with international emergency call (eCall) regulations and that the driver remains connected to Volvo’s suite of remote services.
