Emergency radios, flashlights, TV remotes, garage door openers, clocks, and more all use batteries. Sometimes we have a stockpile of batteries that have been sitting around for years and we don't know if they are any good. Or, if a device stops working, you're not sure whether the battery is to blame. Now you can know whether a battery is still good or drained. Use this 1 device to check the charge on a number of different kinds of batteries. The Ultra last Universal Battery Tester is designed to test more than 12 types of batteries. Types include AA, AAA, C, D, 9V, CR123A, CR2, CR-V3, 2CR5, CR-P2, button cells or other batteries with same voltage. It is designed to test 1 battery at a time, with its state of charge is shown on the LCD screen. You can test rechargeable as well as non-rechargeable batteries. If the test comes back with a good reading, you don't have to throw it out. This tester is NOT for use with lithium ion batteries.
