How Do You Test An Automotive Battery?
An important part of your automotive maintenance should be to make sure you have a healthy car battery. It is best to determine the condition of your battery by testing it in the comfortable confines of your garage rather than finding out the hard way—stranded somewhere with a car that won’t start. Make it a habit to test your car battery every time you change your oil, and you should be able to replace a battery that is failing before it leaves you high and dry. Make sure your battery is fully charged before testing. Either take the vehicle for a long drive during the day or charge it with an appropriate battery charger. Allow the battery to sit for 12 hours after charging so that any surface charge is gone and will not distort testing results. Get the manufacturer’s specifications for your battery and have them handy during testing. If you do not have the original literature that came with your battery when it was purchased, you can usually find the specs on the manufacturer’s webs
