It's compact size allows you to store it nearly anywhere: Your tool box, the glove box in your vehicle, or even your pocket.
I mainly bought this tester to have to check my supply of CR2032 batteries I keep on hand. Tested the tester and it performed as it was made to. It was on sale and I’m happy.
I ordered a battery tester, cr2032's, and Lr44's. I was concerned about the postage and it costing a lot more to ship because it may have been dangerous goods. So I expressed my concern and they called me back within hours! I was haopy to find out it was not going to cost a lot to send, and they sent my order out that day! So awesome! thank you battery mart! You've always been a great company to order from!
This is very easy to use and very inexpensive. Very handy and a must have around.
never had one, usefull tool
It is small / compact, and that makes it easy to store but difficult to use or handle.
I have 3 testers and 2 of them have failed because the label indicating what range was charged and discharged had come lose. The label was getting hit by the needle and causing the needle to stick until you tapped the meter slightly. It was reading everything as discharged because the needle couldn't get to the charged region. Basically, the label adhesive failed and the label curled up blocking the needle. However, When these guys work they are a great tool to help you decide when to toss or recharge your batteries.
It's a good Tester. It didn't come with instructions and took me a few minutes to figure out. It works well and is simple to use.
