I’m going on holiday – should I disconnect the battery?

We do not recommend disconnecting the battery in modern vehicles. Depending on the make, model and age of your vehicle, disconnecting the battery may result in the loss of some of your vehicle’s computer settings.

If you’re going to be away for more than two weeks, ensure the battery is fully charged before you go and, if it has removable caps, check that the electrolyte level is correct. Using a battery charger is also a good idea if you have a reliable friend or family member that can switch it on/off for you whilst you're away. If in doubt, contact an automotive workshop for advice. RAC members can also contact our Motoring Advice team on 13 17 03.
