MOTOPOWER MP0514A 12V Digital Car Battery Tester Voltmeter and Charging System Analyzer with LCD Display and LED Indication - Black Rubber Paint

I love this battery tester. It is super easy to use. It shows the voltage and the level of charge. While the instructions do not indicate, a battery in good condition should show a voltage of about 12.6.

Works well. I had four lawn mower batteries I needed to test, and was accurate and I was able to see which ones were low and dead. Design is very user friendly. Nice small size, and overall good value.

This is a great tool to have around the house, especially if you own multiple vehicles that aren't driven regularly. You simply connect the two cables to your battery terminals, and you'll get both a digital readout, as well as a simple led light to give you the battery or alternator status. This was so handy to have as I recently had to replace both my alternator and battery on my Dodge Durango. The alternator readout gave me piece of mind that the alternator was installed and working correctly. This unit will also warn you if you have the cables hooked up incorrectly. My only reason for not giving 5 stars is it's a bit cheaply made. It's hard plastic, and the rubber sleaves on the clips are very thin and tend to slide off easily. Having said this, the unit is priced accordingly, it's a value priced unit that gets the job done.

Seems to work very well. Wish it could test alternator.

Good and inexpensive product to have in your garage. Allows you to test your battery and alternator so that you can replace them before they break down. I was considering replacing the OEM battery in my nearly five year old car, but the tester shows it is still going strong. I'll keep testing it it periodically and change it when I need to.

works well easy to operate

very nice, did exactly what I wanted it to do

I love this design. Simple to use with quick digital readout with LED indicators of charge quality and alternator output. A very good and inexpensive choice. That said, the battery clamps are extremely light weight and bend easily. The negative terminal clamp was bent on arrival and, as such, would not stay clipped to the battery terminal. I was able to repair (at least temporarily) with needle nosed pliers. Would have happily paid a couple dollars more for quality terminal clamps. With decent clamps, would have given this product 5 stars.
