How to charge a car battery
Your battery’s main purpose is to get the engine started. When your engine sounds sluggish or it’s not catching at all, most times a discharged battery is the culprit. We’ve got some tips on how to charge a car battery so the heart of your car stays pumping.
Does your battery need to be charged?
If you turn your key and … nothing happens, it’s likely you’ve got a discharged battery. To avoid being caught out there’s some ways you can tell your battery might fail before it does:
- Your engine takes a while to start
- The ‘check engine’ light comes on
- The battery looks bloated, it’s leaking or it’s got low battery fluid (if possible).
Depending on the state of your car battery it could pay to do a quick recharge. If the battery looks a little worse for wear, it may be time to get a new battery.
Charging a car battery
Follow our tips on how to use a car battery charger:
- Check your battery for wear and tear and check the battery fluid is topped up (if possible). If the battery’s damaged – get a new one, rather than a charger
- Different chargers work on different batteries. Find your battery type and you’ll know what battery charger to get
- If possible, turn off all electrics and lock the vehicle
- Follow the manufacturer instructions. Some chargers need the battery removed to work, others just need cell caps removed. Even if you’ve charged a battery before, follow the instructions to keep everyone safe
Once the charger is connected it can take up to 24 hours to fully charge a flat battery. Modern smart chargers have a light to indicate when the battery is fully charged.
