Battery tester B2 Black

This Battery Tester is a must-have for quickly checking the charge on a wide range of batteries. The LCD display makes it easy to read, and it works with AA, AAA, 9V, button cells, and more. I love that it’s universal, so I can test multiple battery types around the house. It’s small, lightweight, and easy to use. The included AAA battery is a nice bonus. Overall, it’s a great tool to help prevent wasting batteries and ensures I’m only using fully charged ones.

Works great! Very easy to use.

GREAT TESTER BUT HAD TO REPLACE AFTER ABOUT 2 YEARS. GREAT SINCE YOU KNOW IF ALL OF YOUR BATTERIES ARE DEAD, OR JUST ONE. SAVES MONEY AND IS EASY TO USE AND ACCURATE.

Can’t complain at all. The tester works great and easy to use

After a recent move, my small battery tester gave up the ghost. I find these things to be very useful and being without one while decorating for Christmas was not optimal. For my battery-operated lights, I had to go through my battery drawer pulling out batteries and trying to find combinations (the lights require two or three AA each) that would work. Sometimes one of two batteries would be ok. Sometimes one of three was bad and prevented the other two from powering the lights. In fact, it was so tedious I went out and bought a giant pack of AA batteries at the local hardware store. When this device came in I immediately went back to the battery drawer and tested all of the remaining ones. Several had to be discarded because of either no charge or borderline. I've found that LEDs do not like batteries that do not deliver the full charge and all my Christmas lights are LEDs. As a plus, I had a bunch of older button batteries that, surprisingly, still hold a very good charge. I was thinking of pitching them, but now all I have to do is figure out what device I put them in. What I like about this device is that it tests a very wide range of batteries: your usual-suspect C, D, AA, AAA, and 9v of course. Also most 1.5v button batteries and even 3v button batteries; though larger ones like a CR2450 won't fit into one of the button sockets on the tester, you can check them by holding against the contacts on the 3v button slot. It also tests a range of the 3v cylindrical batteries used in my home security system. Nice. It even comes with a AAA battery to power the tester. Also nice. All-in-all a fine little device and well worth getting

Inexpensive way to test your batteries regardless of size. Very easy to use. Definitely saves time trying to use a battery that is dead or almost dead.

This is the best battery tester on the market for the price. Very easy to use and accurate. Also, can read almost every battery you have, including the flat disc type. Highly recommend it, bought one for every family member.

works great! love that it has so many types to test! Easy to use
