Seems to Work Fine

This tester pegged two batteries whose condition I was pretty sure of. It seems to be very accurate.

Handy and Awesome

It was great to have this tool to make sure I didn't throw away a good battery when it simply requires a new charge. I could have wasted an expensive battery that I thought wouldn't charge...

Brandon Beer
Great price and product

A great product for its price. Useful and easy to use.

Terrica Archer
Just one word- AWESOME!

I strongly suggest car owners to get one of this tester. There are no warnings for nowadays' batteries when they die out, just fail at once. And the dashboard only informs you when the alternator's damaged. This device tests batteries' overall condition, and it is reliable and easy to handle.

Joshua Maryann
Handy tool to get

Perfect for all automotive batteries. Just plug it in and input the info. required. The tester will do the rest and let you know the condition of your battery.
