The HyCell LCD battery tester is suitable for AAA, AA, C, D, 9 V, CR123A, CR2, CR-V3 or 2CR5, for example, and achieves the most accurate results during measurement. To do this, the battery, button cell or rechargeable battery to be tested must either be pressed against the intended location or placed in the appropriate slot. A large LCD display then shows the current capacity on a three-part bar scale (weak - normal - good). Since the result of the battery tester is always accurate, empty batteries can be sorted out quickly and reliably in this way.
