Review on Dlyfull Universal Battery Tester: LCD Display & Digital Voltage Resistance Checker For AA AAA C D 9V 12V 18650 CR123A 2CR5 CR2032 Cells by Joseph Ramos
Fantastic Battery checker!
I love this! Like most of us, I have a lot of battery-operated devices. And I do, sometimes, find a battery in a drawer and I do not know why it is there or how old it is.And with this tool, I can easily and instantly find out if it is brand new, slightly used, or almost dead.The screen is very easy to read. You select the battery type on the dial. Put one probe onto the positive, one on the negative end of the battery. Now the meter, going up in 5% jumps will tell you what percentage of the battery remains.It will also tell you the voltage and the internal resistance of the battery.The probes have spring-loaded tips with textured ends so they grip the battery you push them against.
- ★ RELIABLE & MULTIFUNCTIONAL: With its high ability to detect battery capacity percentage, battery voltage, and battery internal resistance, the precise universal battery meter is great for finding out if your EDC devices need new batteries or if it was device faulty. Such as kids' toys, flashlights, controllers, cameras, etc.
- The battery tester may not provide enough information to diagnose battery problems.
