I use this to check SG off a forklift battery that I'm using in my off-grid solar system. It seems to be working and SG tracks voltage as expected. It's easy to use and does the job. I didn't know how accurate it is as I didn't have anything to compare it to. I have a couple of criticisms, I wish it had numbers marked between fair and good so I don't have to estimate, and I see small cracking around the edges which I know can come from the method used to weld the 2 halves together or if solvent is used to clean it in the manufacturing process, but to be fair, I have also left this under the metal cover of my battery outside, so it has been exposed to the elements and temperature swings below freezing. So far no leaks but even if the long term durability isn't there, it's cheap enough to just buy another one.

I'll have to use it on more batteries to truly know if it is working properly.

Works fine, not exactly how it temperature compensates but says it does?
