The vehicle has an alternating current generator.
The start battery is an Absorbed Glass Mat (AGM) 12-volt battery that is dimensioned for use in vehicles to support electrical systems and functions and regenerative charging.
The service life of a battery is affected by factors such as driving conditions/style, the number of starts, climate, etc. Extreme cold may also further decrease the battery’s starting capacity.
- Never disconnect the start battery while the engine is running.
- Check that the start battery is correctly connected and that the clamps on its terminals are properly tightened.
Warning
- Never expose the battery to open flame or electric spark.
- Do not smoke near the battery.
- Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces. If contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.
Warning
PROPOSITION 65 WARNING!
Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the state of California to cause cancer and reproductive harm. Wash hands after handling.
If the start battery is being charged, the support battery will also be charged.
If an external auxiliary battery is used to start the vehicle, use the connection points in the engine compartment. The start battery's terminals should never be used. See the following illustration for the location of the connection points.
Positive connection point
Negative connection point
Only modern battery chargers with controlled charging current should be used to charge the start and support batteries. Quick charge functions should not be used and could damage the battery.
Important
- The infotainment system's energy-saving feature may not function correctly or at all, and/or a message may be displayed if a battery charger or jumper cables are not connected properly.
- The negative terminal on the battery must never be used to connect a jumper cable or a battery charger. Only the ground point on the chassis may be used.
Note
- The service life of the start battery is shortened if it becomes discharged repeatedly.
- The service life of the start battery is affected by factors such as driving conditions and climate. Extreme cold may also further decrease the battery's start capacity.
- Because the battery’s starting capacity decreases with time, it may be necessary to recharge it if the vehicle is not driven for an extended period of time or if the vehicle is usually only driven short distances.
- Driving for at least 15 minutes a week or connecting the battery to a charger with automatic maintenance charging will help keep it in good operating condition.
- Keeping the start battery fully charged will help maximize its service life.

Warning
- When replacing the start battery or support battery an Absorbed Glass Mat (AGM) must be used.
- When replacing the start battery, a new battery with the same specifications and dimensions must be used. The battery should only be replaced by a trained and qualified Volvo service technician.
