How long it takes to charge a car battery whilst you're driving?


Answer from the Stoneacre aftersales team:

Hi Ryan, that's a great question!

It varies depending on how much charge is in your battery before you start driving and your driving style. Your car battery is charged by your alternator. Often, when a battery fails, it's due to a fault with the alternator.

Generally, if you can keep your engine RPM up, your alternator will charge your battery at a faster rate. If you are driving on a motorway, you should be able to charge your car battery in 30 minutes. If you are driving in the city, it may take an hour or more.

If you've been having problems with your battery, you can bring it in to one of our service centres and our technicians will be more than happy to check it for you.
