How long does a battery last?
A 12-volt battery generally lasts four to six years. Short trips, cold weather, long periods parked and heavy electrical demand shorten its life. A voltage and capacity test before winter can reveal a weak battery before it leaves the car unable to start.
Signs of a weak battery
Slow cranking, dim lights, dashboard messages and difficult starts are common signs. They may also indicate an alternator or charging fault, so test the charging system before replacing the battery.
Battery replacement cost
A replacement usually costs €90–€250 fitted. Start-stop vehicles often require a more expensive EFB or AGM battery and may need electronic registration after installation. Match the specified technology, capacity and starting current.
