Really good device. I needed to use it shortly after its arrival! Have used it two other times since. It is good to know when the battery is dead or just needs recharging!

Great tester for the price
I'm a professional automotive tech and use this everyday in the shop. It has been accurate for me and I like that it gives me a battery health percentage.My one complaint would be that the clamps could be better. There is a little plastic tab that fits into the copper contacts and it prevents good contact with the terminals at times. Sometimes it tells me to check connection and others it just gives me a very weak reading.

At home diagnostics for very little money, saves me time
Very simple to use, tells me strength of the battery and can get a sense how soon I will need to replace.Also tell me how effective my battery charger is in regenerating mode in restoring health of the battery.

Really wish I bought one sooner
Wasted years with wondering if this or that car battery really was failing or failed. Endless attempts at charging repair charging drain and fill charging add acid etc etc etc. This tells me those I have sitting around are junk and the very few are surviving for other uses. Showed a new battery in a car with a possible parasitic drain was on its annual three year battery failure replacement parade that lets me get under the warranty as opposed to finding out a month too late. Information is power and this actually saves time on chasing dead endears.
