Charging your vehicle’s battery is a much more efficient way of keeping your car running than jump-starting it once the battery has gone flat. It’s also much better for your battery in the long term.
Thankfully, with a battery charger to hand, it’s not too difficult to do it yourself. Just follow the simple steps below.
Check your charger
Always make sure you’ve read the operating instructions on your specific charger, and make sure that it’s fit for purpose.
If your vehicle has Stop/Start Technology, it will be fitted with either an EFB (Enhanced Flooded Battery) or an AGM battery (Absorbent Glass Mat), so you’ll need a smart charger to charge these types of battery safely.
Before you start charging, ensure the battery terminals are clean and free from corrosion. If not, clean the terminals before charging, as this helps to ensure a good connection.
With that prep work done, you can now connect your charger to the battery. Some manufacturers may advise disconnecting the battery during charging, so always check your owner’s handbook before you continue and follow their recommendations.
Ensure the charger is switched off, then you should connect the red positive (+) lead to the positive (+) terminal on your battery. Always connect the black negative (-) lead to the negative (-) terminal on the battery last. Ensure the charger is situated away from the battery and switch the charger on to commence charging.
Keep a close eye on the charger, and once your battery is fully charged, switch the charger off and disconnect it from the mains. Make sure you disconnect the negative lead first, then the positive lead last.
And that’s it. Your vehicle should be charged and ready to go.
