Battery Tester, Universal Battery Checker Small Battery Tester for AAA AA C D 9V 1.5V Button Cell - Battery Tester for Household Batteries

Easy to use and accurate

I bought this battery tester specifically to test 4 brand new D batteries I just purchased to use in a touchless trash can. The lid sensor stopped working after a year and a half so I replaced the batteries with 4 new ones. The sensor still didn't work and I was ready to toss the trash can out but then decided to buy this battery tester first. I didn't expect that 4 brand new copper top batteries would be the problem but it turns out they were! Two tested DOA and two tested very low. The batteries with the 10 year guarantee weren't even good for 10 minutes! Thanks to this battery tester I saved $$ by getting a refund for the bad batteries; I saved money by not having to buy a new kitchen trash can; and, equally important, I saved a big hunk of metal from ending up in the landfill. I then tested the old batteries that I had saved up to dispose of properly. Turns out some of them were still good. Think about it, when a remote stops working, most of us change both batteries which is wasteful. Now I can test the batteries and just change out the bad ones. The tester is easy to use but sometimes I have to play around with positioning the larger batteries. btw, I'm sure most of you know to recycle ALL batteries so that toxic chemicals such as cadmium, lead and lithium don't end up in our landfills and leach into our environment. Rechargeable batteries are more toxic but regular alkaline batteries are toxic too. 12/22/22 over 2 years later and this still works like new! :) 4/15/2024 still working!!

The WeePro Universal Battery Checker feels like a navigator’s indispensable tool, guiding one through the sometimes turbulent seas of household and electronic batteries. Compact yet robust, it offers clear, reliable readings for AA, AAA, C, D, and 9V batteries, making it easier to avoid unexpected power shortages during crucial moments of adventure—or daily life. Its simplicity is deceptive; despite its small size, it provides accurate diagnostics that save time and prevent frustration, much like a first mate keeping the ship in order. There are minor drawbacks. Extremely worn or corroded batteries may yield inconsistent readings, and the display, though functional, could be slightly larger for quick reference. Nevertheless, for any captain of a household or gadget-filled domain, this battery checker proves both practical and trustworthy. Four stars for a device that combines reliability, versatility, and ease, keeping your fleet of batteries ready for action.
