Can this really tell you if your battery has gone bad?

yes it can really tell you if your battery is gone bad and it can tell you exactly why because sometimes batteries will still register as 12 volts which is normal but be extremely weak. it can also pinpoint if your battery is actually bad or if your alternator isn't charging the battery and it's not just limited to the alternator this can also show you if other things went bad that are also mimicking a bad battery like the diode or the starter or the generator have gone bad. there's a ton of other things it can do to help you really know what's going on with your battery or the charging system in your car.

Bah that was quick. Wanted to add this to my toolbox. Live in Texas and car battery issues are common.

Still good as of 3:50pm EST. You have to apply the 21% coupon first, then the coupon code given in the OP during checkout/payment. That'll get it down to $7.81 before tax.
