Car Batteries & Winter – Tips on how to keep your battery running strong

August 26, 2025

 

Did you know it’s more common to experience a flat battery in the cooler months than at any other time of the year?

Car batteries need regular warmth and energy to stay in good working order – even when your car isn’t in use

Here are our top tips from the M&R team to help keep your car battery functioning at its best:

  1. Take it for a decent drive once a week – Aim for longer trips rather than short runs. Short drives often aren’t enough to replace the energy used to start the vehicle, which can slowly drain the battery.

  2. Check your battery’s condition – Ideally, this should be done before winter begins, but it’s never too late. Look for cracks, broken pieces, leaks, corrosion, bulging, or any signs of damage.

  3. Park in a sheltered spot – If you can, park in a garage, covered area, or underground space. If that’s not possible, aim to position the front of your car out of the direct wind.

  4. Monitor and charge regularly – Keep an eye on your battery and top it up when needed. A fully charged battery is less likely to freeze, so make sure your car is getting regular use in winter.

  5. Reduce unnecessary strain – Lights, radio, and heating can all drain your battery. Turn them off before switching off the ignition. On cold mornings, let the alternator charge for a moment before driving away.

Pro tip: Don’t forget to regularly check your battery or get it professionally tested to avoid any unwelcome surprises.
