This tester is one of those products that once you have it, you won't know how you lived without it. If you use CR123A batteries for your flashlights, wireless sensors, or other electronic devices, you will love this compact tester from Rexford Tools. Simply pop in your CR123A battery and the display quickly indicates the battery's exact voltage level. If your job requires you to install or service wireless devices such as motion sensors or door contacts, this tool is the perfect companion for troubleshooting devices that are not working properly.
One of our favorite things about this product is that the manufacturer is using 3D printed housings. In addition to looking awesome, it is also extremely rugged!
In addition to CR123A batteries, this product will also test IMR 18350, RCR123A, and any other batteries that share the same physical size as a CR123A battery (up to 6VDC).
