How To Rejuvenate A Car Battery At Home

This instructional tutorial demonstrates how to rejuvenate a car battery at home, when it no longer holds a charge and you don't even need to remove it from the car. If your car doesn't start, no matter how long you've just had it running, it's probably sulfated but before you spend more than $100 on a new one, try this repair first and you will likely gain several months of reliable service before having to replace it for good. You can do this fix without removing the car battery too... great for cars with small engine bays, difficult access to the battery or no access because the battery is buried somewhere under the washer bottle, alternator and tertiary infotainment computer... but if that's the case, you've got bigger problems than a dead battery ;)
