Advance Auto does have a battery tester. The tester is located in the electrical aisle and is used to test the battery’s voltage. To use the tester, first make sure that the battery is fully charged.
Then, connect the positive lead of the tester to the positive terminal of the battery and the negative lead of the tester to the negative terminal of the battery. If the battery is working properly, the voltmeter will read 12 volts. If it reads less than 12 volts, then the battery is discharged and needs to be recharged.
