Going on holiday is the perfect chance to unwind, but leaving your car unused for days or weeks can take its toll — especially on the battery. Whether your car’s parked at the airport or sitting at home while you’re away, a flat battery is a common nuisance. Here are some practical tips you can actually use:
Give your car a good run before you go
Try to drive your car for at least 20 to 30 minutes the day before you leave. This helps ensure the battery is fully charged and ready to sit idle.
Choose secure, well-used airport parking
Long-term airport parking can mean your car sits untouched for weeks. If possible, pick a car park where vehicles are regularly moved or checked. If that’s not an option, ask a friend or neighbour to start your car every now and then.
Unplug all devices when the engine is off
Dash cams, phone chargers and sat navs plugged in can slowly drain your battery even when the engine isn’t running. Make sure you unplug them before leaving your car.
Double-check all lights are off and doors closed properly
Interior lights, boot lights or glovebox lights left on can cause a flat battery. Take a moment to check everything’s switched off and all doors and the boot are fully closed.
Ask someone to start your car if you’ll be away a while
If your car will be parked for longer than a week, ask a trusted friend or neighbour to start it and let it run for 10-15 minutes every week or so. This keeps the battery charged and the engine lubricated.
Consider a trickle charger if your car sits for long periods
If you’re leaving your car at home during a long holiday, a trickle charger is an easy and safe way to maintain your battery’s charge.
