Thexton THE115 Battery Tester / Hydrometer from Amazon

[Maraakate]

Been trying to find a decent hydrometer for these small batteries for quite some time. The reviews on this one seemed pretty good and it's made in the USA.

The only modification I had to do was get a 1/8" ID x 1/4" OD fuel line for weed whacker and cut off about 2 inches. Heat up one end with a heat gun to get it to fit over the hydrometer. After that, works great and can finally test my batteries.

Current price is about $10, you can get it here https://www.amazon.com/Thexton-THE11.../dp/B000P6WS22

Love the description, "battery powered". Yeah, I guess it is since it doesn't work until you insert into a battery and draw some fluid.

Yeah, kinda silly. It works fine, so I can't complain too much.
