Maintenance and lifespan

Typical lifespan

Lead-acid starting batteries commonly last around 3 to 5 years. Heat, frequent short trips, deep discharges and high electrical loads shorten their life.

Signs of wear

  • Slow or laboured cranking
  • Battery or charging warning on the dashboard
  • Start-stop working less often
  • Corrosion on the terminals
  • Swollen or leaking case
  • Needing jump starts

Basic checks

  • Measure the rest voltage with a multimeter after the vehicle has been off for several hours
  • Ask a workshop for a load or conductance test
  • Clean and tighten the terminals
  • Check that the hold-down clamp is secure
  • Have the charging system tested if the battery keeps going flat

Safety

  • Wear eye protection and gloves
  • Keep sparks and flames away: batteries can release hydrogen
  • Disconnect the negative terminal first and reconnect it last
  • Never short the terminals with tools
  • Recycle the old battery at an authorised collection point

AGM AGM: never add water and use a charger with an AGM mode; overcharging and heat shorten its life.

General guidance. Always follow the battery and vehicle manufacturer instructions.
