Battery Tester different than multimeter
I have a multimeter and tested my 4 & 1/2 year old car battery and the reading was 13.7. When I went to Autozone, it said "bad" I replaced it under warranty.
Can anyone suggest what so special this Battery Tester they will that checked the battery was bad?

What he means by that is:
A battery load tester measures the CCA (cold cranking amps) the battery has. Yours failed because it had a low number, deeming it bad.
Battery voltage doesn't necessarily mean the battery is good, although it is usually an indicator of bad health if the voltage slowly drops while unhooked from the positive and negative terminals.
