I use these at work. This one is very durable, and very accurate. I put a piece of white duct tape on the back, to give a cleaner view of the reading.

Old style, proven device. Only time will tell how the bulb holds up here in Yuma AZ.

This one is better, it has the specific gravity reading on a scale, rather than the floating balls.

I'm so glad I spent the extra few bucks to get this battery tester over the basic ones. It's high quality, Made in USA. It has the specific gravity numbers, which I was looking for, as this gives you more information to work with. It does have the Low, Fair, Good indicators too, but having specific numbers just provides you with a better understanding on the health of your battery.The indicators are also PRINTED on the plastic, instead of a sticker that over time gets peeled off from acid or just regular use and then you're stuck with a uselesss piece of plastic. Big plus!I actually read the directions for once and washed it out with soapy water and multiple clear water rinses afterwards. I want to take care of this since it's well made. I'd recommend this!

I just received this and tested several batteries yesterday. It seems to be well constructed. It is easy to use and read. I did need my reading glasses to read the instructions and to read the exact reading. I could easily see which cells were good or bad at a glance. I was able to adjust acid levels and hopefully saved a huge H9 battery with one low cell. The gauge comes in a nice pouch and has a lifetime warranty. It is marked Made in USA. Quality is much better than the cheap coolant testers I've used in the past, which are a similar tool.

Works great and as advertised. I learned to get a proper reading I learned to slowly bring battery fluid into the reading chamber to reduce air bubbles clinging to the measuring float. Air bubbles on the float tend to give false readings. I would also tap the device to dislodge any extra air bubbles. Simple and easy to use.

Pretty simple and easy to use. Let me know that my battery was holding water instead of acid. I feel like you should have this with you before you buy an rv/trailer and make sure you don't inherit a dud battery.
