Starter Battery

~3min read

The starter battery is used to start the electrical system and power the starter motor and other electrical equipment in the vehicle. The vehicle has a single-pole electrical system that uses the chassis and engine mount as conductors.

The vehicle is equipped with a voltage-regulated alternator.

The starter battery is a 12 V battery, dimensioned for the carbon dioxide-reducing functions Start/Stop and regenerative charging and to support the function of the vehicle's various systems.

The service life and performance of the starter battery are affected by factors such as driving style, driving conditions, climate, battery discharges, number of starts, etc.

  • Never disconnect the starter battery while the engine is running.
  • Make sure the cables to the starter battery are correctly connected and the clamps are securely tightened.
  • Batteries generate hydrogen gas, which is highly flammable and explosive.
  • Do not connect the jumper cable to any part of the fuel system or to any moving parts. Avoid touching hot exhaust manifolds.
  • Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics, or painted surfaces.
  • If contact occurs, immediately flush the affected area with water. Seek medical attention immediately if eyes are affected.
  • Never expose the battery to open flame or electrical sparks. Do not smoke near the battery. Failure to follow the instructions for jump starting can lead to injury.

Starter Battery Service Life and Capacity

The service life of the starter battery is affected by several factors, such as number of starts, battery discharges, driving style, driving conditions, climate, etc. The starting capacity of the battery gradually decreases over time. The battery must therefore be recharged if the vehicle is not used for a long period of time or if it is only driven short distances. Severe cold further limits starting power. If the starter battery becomes discharged too many times, its service life will be shortened.

To help keep the starter battery in good condition, the vehicle should be driven at least 15 minutes per week or the battery should be connected to a battery charger with automatic trickle charging. A starter battery that is always kept fully charged has the maximum service life.
