It's designed so that both customer and technician can see the state of the battery acid. This battery tester is economical; your first cost is your only cost. There are no replacement parts, and it has rugged construction and unbeatable quality. There are no difficult float reading to be observed and no temperature tables required. Review: Cheap, easy to use battery tester - 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. Review: Great price great quality product! - Does EXACTLY what it’s supposed to do!

This is Florida, humidity tend to be high and I clean it after every use. If you neglect it and leave grease or other residues on it the rubber will degrade and will not be able to do its job. It Depends on the care and environment where you operate. It is rubber after all. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cheap, easy to use battery tester *by K***I on December 23, 2024* I use this to check SG off a forklift battery that I'm using in my off-grid solar system.
