Don't needlessly throw away batteries that still have power remaining! The InfiniCell â„¢ Battery Checker has a dual scale that tests and measures battery voltage or capacity by simulating load tests to check if the battery will work in use. The portable battery works to test AAA, AA, C, D, N, 9V and button batteries whether they are general-purpose, alkaline, or rechargeable. As an added bonus, this battery checker can also test fuses and bulbs. (Batteries not included)
