To hot to handle
I'm unable to give 5 stars as I've only used it once, it worked well. However, using the battery that came with it caused concern. I fitted the said battery and the machine didn't respond. On removing the battery, it was extremely hot and the heat caused me to drop it to the floor. It took sometime to cool before I discarded it. The device worked satisfactorily when a new battery from my supply was inserted and did not overheat. People beware of the battery that comes with this device. I'm not sure what would have happened should I have not removed it. This could be a one off, however, be mindful.

This tester works great. I bought it to replace a different tester that I was using. This tester is so easy to use. And I like how it can test so many different size batteries.

I have a number of battery-operated devices and like to take the battery out when not used over a period of time (previous bad experiences with leaked battery juice). This device works on all my battery types and I can tell in an instant which battery is good even though they are all mixed up in my battery storage compartment.

電池残量が簡単に計測出来る バーとweakなどの文字表示だが境界の電圧が数値で示されればより分かりやすい

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.
