Can I change a car battery myself?
On older cars, changing the battery is fairly simple and involves a spanner and a few minutes of your time. However, when it comes to modern cars, replacing your old battery isn’t straightforward given the complexity of most modern cars and the need for your battery to be coded to their system.

How long does it take to change a car battery?
The whole process of changing a car battery usually takes around 15 to 30 minutes.
What are the signs that a battery needs replacing?
Cars will always have tell-tale signs if something is wrong, and it’s no different when it comes to car batteries. Undertaking regular checks will help determine if your car battery is on the way out, and knowing the symptoms of a worn-out battery will also help you to prevent a potential breakdown at some point in the future.
Your battery might need replacing if:
There is a build-up of green, powdery residue on the terminals.
You can see a battery warning light on your dashboard.
The engine takes longer to start and feels like it is struggling.
Where is my car battery located?
Most drivers would assume that the battery is located at the front, but never assume anything – especially with cars. These days, only about 58 per cent of batteries can be found under the bonnet with about 40 per cent now in the boot (to help with weight distribution) and the remainder inside the cabin.
How can I make my car battery last longer?
On the whole, car batteries are pretty good at looking after themselves. However, there are definitely some ways in which you can help prolong a car battery life and maximise the return on your investment:
Try to avoid too many short journeys
Your car battery gets a good workout every time your turn the key on the ignition, recharging itself as you drive along. But if you only do short journeys, your battery doesn’t have time to fully recharge, and repeated short journeys will result in the battery voltage steadily falling. If you can, drive your car frequently and try and plan in longer journeys if possible. Alternatively, invest in a battery charger as that will help to maintain the correct voltage.
Keep usage to a minimum when the engine is turned off
Batteries love being at 100 per cent charge, so try to avoid having the headlights on when you're not in the car. The same applies to interior lights and the Infotainment System.
Ensure your battery stays clean
Make sure the top of your battery is clean, dry and free of dirt. The battery terminals will corrode over time and keeping them clear of any build-up of residue will help extend the lifetime of the battery.
Don’t leave your car unused for long periods
It's vital that car batteries are kept fully charged to avoid losing charge (sometimes known as ‘self-discharge’). Prolonged periods of non-use will drain the battery. If you’re not going to be using your car for any amount of time it’s worth thinking about a battery charger to make sure your battery is in tip-top condition.
