Starter battery

The starter battery is used to start up the electrical system and drive electrical equipment in the car. The hybrid battery is used when the internal combustion engine is started.

The starter battery is a 12 V AGM battery (Absorbed Glass Mat), designed for regenerative charging, and to support the functionality of the car's different systems.

  • Never disconnect the starter battery when the engine is running.
  • Check that the cables to the starter battery are correctly connected and properly tightened.

 Warning

  • The battery can generate oxyhydrogen gas, which is highly explosive. A spark can be formed if a jump lead is connected incorrectly, and this can be enough for the battery to explode.
  • Do not connect the jump leads to any fuel system component or any moving part. Be careful of hot engine parts.
  • The battery contains sulphuric acid, which can cause serious burns.
  • If sulphuric acid comes into contact with eyes, skin or clothing, flush with large quantities of water. If acid splashes into the eyes - seek medical attention immediately.
  • Never smoke near the battery.

Starter battery service life and capacity

The service life of the starter battery is influenced by a number of factors, such as the number of starts, discharges, driving methods, driving conditions, climate conditions, etc. The battery's starting capacity gradually falls over time, and therefore it needs to be charged if the car is not used for any length of time or if it only travels short distances. Extreme cold further limits starting capacity. The service life of the starter battery is adversely affected if it is discharged many times.

To keep the starter battery in good condition, at least 15 minutes of driving a week is recommended, or connecting the battery to a battery charger with automatic trickle charging. A starter battery that is always kept fully charged has maximum service life.
