I bought them all, it really helps me at work
This "EverStart Auto Mini Battery Tester" is a fine over sized eyedropper, but it is not It is not a hydrometer. It is worthless as a battery tester. None of the four ball float even with a known good, fully charged lead acid battery for a car. I tested it on an auto battery before and after charging. No difference in ball floating with this device. I tested the same battery with a decent hydrometer; the specific gravity went from 1.1 to 1.3 with charging. Also the voltage went from 11.8v to 12.8 after charge. I recommend not buying the EverStart Mini Battery tester.
I bought one a year ago. A few days ago I tried to use it again. Two of the 4 floaters were completely disintegrated. If I were supposed to rinse the tool after use, the instruction did not say so. Apparently, the material isn't acid resistant.
