Batteries don’t usually last for more than about five years
and it can be as little as two to three years if you mainly do short journeys, according to the AA. So as winter approaches, it might be worth investing in a new one if yours is nearing the end of its working life.
If you do buy a new battery, the RAC recommends having it professionally fitted, because if the leads are connected incorrectly you can do serious damage to your vehicle's electronic system. Old batteries need to be carefully recycled so check if this is part of the service too, otherwise you'll need to take the old battery to your local recycling centre.
