Review on ⚡ The Ultimate Thexton THE115 Battery Tester: Enhance Reliability and Performance! by Branden Type

We use them on a golf course where we have about 40 carts with 6 4 cell batteries each. These are 960 cells that need to be checked periodically. Other hydrometers are big, bulky things with a pressure gauge, a big bulb, and a tube. This guy is fast, bam-bum-bum. It is also good that it balances the temperature. In fact, I don't need to know the numerical specific gravity. I need to know the relative state of each cell. You drop the thing, press two or three times to make sure you only get liquid out of that cage and look at the beads, if one floats it's 25% charged, if two floats it's 50% , up to 3 or 4 floating point. The cell test takes literally 2 seconds. It is also made of glass and comes with a handy carrying case. And for those who care, it's made in the USA.
