Keeping the 12 V battery charged
The 12 V battery is charged whenever the motor is running. However, it charges better when driving the car. Using a lot of energy without allowing the 12 V battery to charge can lead to low battery level and electrical features can be reduced or disabled.
When you aren't driving the car, avoid using electrical functions such as:
- air conditioning
- headlights
- wipers
- radio
- centre display
- or the 12 V socket and USB ports.
If you still need to use certain features while the car 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 car with an external battery.
Servicing and replacement
The 12 V battery is maintenance-free. Contact an authorised Volvo workshop if the 12 V battery needs to be replaced.
