5.0 out of 5 stars Works Well -- Even with NiMH Batteries, January 1, 2010

I spent many hours researching battery testers and decided to purchase the Gardner Bender GBT-500A. It has worked very well. It is easy to use and has been very accurate. I was a bit concerned that it did not list NiMH batteries as being batteries that could be tested. But after more research I noted that NiMH batteries are the next generation of rechargeable batteries (replacing NiCAD). So far the tester has worked like a champ with the NiMH batteries as well as the other kinds listed. I highly recommend it.

5.0 out of 5 stars Exactly what I wanted, but not for careless users., October 4, 2009

The closest thing I could find in the local stores was a $20 meter (on sale) that tests only some of the battery types on this one's front panel while providing many other features I don't need (because I have another meter for those). I like having the option of using just one probe while resting the other battery terminal on one of the metal contacts on the panel. BUT, as the users' manual warns, that means it is not idiot proof. Using the wrong probe with the wrong contact will short circuit the battery, which wouldn't do either the battery or the meter any good.

5.0 out of 5 stars Best Battery Tester Yet, October 21, 2009

It's really that good. Will test just about any small battery made; and several no longer made. Well built, accurate, and very versatile. Will pay for itself in short order due to the tendency for batteries to drain at different rates. Just because the device says battery low does not mean ALL the batteries are low. You will keep batteries that otherwise would have been tossed, and you will be able to not find yourself in a jam because you ventured forth with borderline batteries in your communicator, flashlight, camera, or other important device. Keep it where you store your batteries so you won't have to go hunting for it. I hang mine on a pegboard in the package it came in. This is one of those devices that you may not use daily or weekly, but when you need it your glad its there.
