Battery Tester for AA AAA C D 9V, 1.5V Button & Household Batteries Checker

Before this, testing batteries meant finding my bulky digital VOM, connecting its wire probes, then taking the time to remember how to get it to test batteries. The Dlyfull Battery Tester eliminates all that hassle. All you do is move the slider to the right position to accommodate the battery you're testing, hold the battery in place, and look at where the needle on its gauge is pointing. It works with all the standard 1.5V and 9V batteries (including miniature disc-shaped ones). The only thing it doesn't do is test lithium batteries with other voltages, for example the CR2032 is 3V. And of course it doesn't require a battiers to operate (which is another advantage over using VOMs for this application). This is a useful, inexpensive item that now lives permanently in my desk drawer. So far it's saved several batteries that I would have discarded due to their age.

Works well good product

This is a neat little gadget. I would STRONGLY encourage the manufacturer to enclose a copy of the how-to-use pictures that are on the web site. The 9V is not intuitive.

Works just fine for such a low cost!

Arrived quickly. My husband says it was just what he needed . Very happy with our purchase.

Great little tool to keep people from throwing good batteries away.

Difficult to use. It felt “flimsy”, wouldn’t hold its place as I tried to measure things. I had to return it.

Easy to use
