Review: Easy to use - I have a few batteries that have issues, so I decided to pick up a battery tester. The one in the pictures is a lawn mower that constantly needs jumped, so I wanted to make sure the battery itself was good. The unit is actually powered by the battery that you are testing, so it's as easy as hooking up your positive and negative and then entering your CCA. I was able to run it off of a powerbank on a completely flat battery, but I think it will work best if I charge the suspect battery first, and then test so that I get a true reading. The screen is bright, the clamps are strong, the unit feels sturdy, and it works well as a quick check on a battery you're unsure of.
Review: False advertisement - This product says it will test 6 volt. When you receive the product it says it doesn't not test 6 volt. I didn't find out soon enough so I got ripped off!!!!!!
