It really depends on what situation your car is in. If it doesn’t need much charging and you’re only topping the battery up, it could take as little as 30 minutes. If your car is nearly flat, it can take days to recharge your battery fully. In most cases, you will know how long your car battery will take to charge because your charger will show a progress bar. If you are not using something that shows this, keep an eye on your car battery by checking your dashboard every so often. The best practice in most cases is to leave your car overnight to charge, with the engine obviously switched off. The RAC recommend that you go for a slower charger where you can, to avoid overwhelming the car battery.
Charging your car is super simple, provided you follow these quick and easy steps. First, make sure you have the right charger for your car. This sounds simple, but doing your research and finding the right charger is the first big step to re-charging your car and one that you can’t get wrong. Next, make sure all the contacts on the battery and the charger are clean. Look out for signs of corrosion and dirt, as this will need to be cleaned before charging your car. Then, disconnect the car battery negative first and reconnect it to ensure no currents are passing through since you cleaned it. The next stop is connecting the charger to the battery. Halfords recommends that you keep the charger as far away as possible from the battery and never place the charger on top of the battery. This avoids any overheating issues. Finally, turn on the charger, if it hasn’t already switched itself on automatically, and you’re good to go!
