Review on Multi-Purpose LCD Display Universal Battery Tester For AA AAA C D 9V CR2032 CR123A CR2 CRV3 2CR5 CRP2 1.5V/3V Button Cell Batteries by Logan Goozmer
Shows Many Batteries "Good " When They're Not
This tester is easy to use and the scale is legible and logical. However, for many batteries they will still register near the top of "Good" when it's clear from what they're had to be removed from that they're not. This is particulary true of CR123A batteries. Frankly, I have never had any bad battery register as "weak" or "poor". Is this device truly measuring resistance in the battery or is it just confirming residual voltage?
