Keeping the 12 V battery charged
The 12 V battery is charged whenever the motor is running. However, it charges better when the vehicle is being driven. Using a lot of energy without allowing the 12 V battery to charge can lower the battery level, and electrical features may be reduced or disabled.
When you aren't driving the vehicle, avoid using electrical functions such as:
- air conditioning
- headlights
- wipers
- radio
- center display
- or the 12 V outlet and USB ports.
If you still need to use certain features while the vehicle is stationary, turn the motor off to use less power.
If the battery level is below a certain point, you will need to charge it with an external charger or jump-start the vehicle with an external battery.
Servicing and replacement
The 12 V battery is maintenance-free. Contact an authorized Volvo workshop if the 12 V battery needs to be replaced.
