How to charge a flat battery

 

Advice

 

It happens to just about all of us: the sinking feeling when we turn the ignition switch and instead of the car’s engine roaring to life we hear a quiet, disconcerting ‘click’. Yes, you can jumpstart your car, but unless you are going to drive your car for long enough to charge the battery sufficiently, there’s every chance that you will find it flat again soon. And obviously you need another car to jumpstart from. A flat car battery is a headache, but if you are prepared you can charge it quickly and easily.

This is what you should do

1. Firstly figure out why the battery is flat. If you haven’t driven your car in a few weeks or even months, the battery might just have slowly drained. Alternatively (and more commonly), you might have left the lights on or a door improperly closed so that an interior light stayed on.

 

2. You’ll need a battery charger, often called a trickle charger because it delivers power at a trickle to slowly and safely charge the battery. You will also need access to a plug point, because battery chargers use mains electricity.

 

3. Open the car’s bonnet and identify which battery terminal is positive (red) and which is negative (black).

 

4. You can charge the battery while it is in the car or you can remove it and then charge it. If charging in the car you don’t need to remove the terminals before doing so.

 

5. Make sure your car is switched off. Connect the positive cable of the charger to the positive terminal on the battery.

 

6. Connect the negative cable of the charger to the negative terminal on the battery.

 

7. Plug the battery charger into the mains electricity supply. Turn it on, and leave your battery to charge for at least six hours, or until the charger indicates that the battery is fully charged.

 

8.When the battery is charged, turn off the charger and unplug it. Then remove the negative cable from the battery and then remove the positive cable from the battery.

 

9. If the battery doesn’t hold its charge, take it for testing at a battery centre.

 

Note

Remember: A car battery doesn’t just start your car – it keeps it running. A dead battery won’t be able to keep your car’s engine running, even if you jumpstart it. Most battery centres will test a battery for free, so if in doubt get a battery tested before charging it.
