MOTOPOWER 12V Digital Car Battery Tester Voltmeter Charging System Analyzer with LCD Display, High Accuracy

Very easy to use. I would buy again

Seems pretty good, don't get to use too often but would recommend.

Works much better than the one I got from Amazon.

very easy to use...works as should..good value

Good to have

I love the product as it is feature rich, especially it records lowest voltage when you starting the engine which is very useful as if the voltage is higher than 9.6V = The battery is still good. Highly recomended!

good price item works as it should no problems.

I thought this was good to check the voltage of your battery, but I'm not sure how accurate is because I don't have a 2nd meter to verify that. However, I had to keep reattaching and attaching and detaching the red bracket. I'm not sure why. It just didn't seem to fit right onto the positive terminal. But, easy to use. I didn't try all of the options.

Wild all over the place results.No calibrated at all. Not even a kids toy. This tester is telling me my brand new battery is poor with 9cca and some wild internal resistance 285 number. The battery is brand new. Two other quality testers confirm perfect health. Return

Does not text anything unless you can crank the car that makes no sense if I could start the car I won't need this device. I wanted to see if the battery was dead before I bought another one. This will be my last time ordering anything from you guys anymore. This is the second item that I've gotten from you that doesn't due what the advertisement says it does. SO LONG I WILL SPEND MY MONEY ELSEWHERE!!!!
