Battery Tester, Dlyfull LCD Display Universal Battery Checker for AA AAA C D 9V CR2032 CR123A CR2 CRV3 2CR5 CRP2 1.5V/3V Button Cell Batteries, 1x AAA Batteries Included

This is an ESSENTIAL, Well Designed Product and everyone who uses batteries or has battery-operated products (all of us) needs one otherwise, you have no idea of the charge-status of your batteries... and don't just assume that batteries are always fresh with full-charge right out of the package or fresh when shipped/supplied with a battery-operated product. I have owned/used several battery-testing products and this one is by far the most versatile, convenient, quick and easy-to-use. Always TEST (even new) and DATE batteries (mo/'yr with a fine point 'sharpie' pen) at the time batteries are put into service in a device/product. Fortunately, manufacturers are trending towards more rechargeable batteries, but until then we all need our own battery 'tester' to know the charge-status of our batteries. This battery testing product is quick, easy-to-use and accurate... I use mine frequently and I would repurchase.

I wasn't sure when I ordered it if it would really work for my batteries, but by they do I have all different sizes and it seems to find a way to do them all. I'd recommend this to anybody looking to check their batteries to make sure they are charged.

De un buen material hasta el momento me ha servido para despejar mis dudas sobre las pilas de diferentes tamaños que tengo. Soy de Argentina. La pantalla no se visualiza de noche en la oscuridad.

Great quick tester. I have one in my tool bag, house, and shop

Super easy to use, and gives a very clear estimate of how much life the battery has left. Has saved us from tossing batteries that were still good. Really glad I bought this!

I love this product. Not having wires to break is terrific.

Helpful to test all types of batteries.

Tested on a couple of battery types and it works just fine
