DLYFULLUniversal Battery Tester with LCD Display, Multi Purpose Small Battery Checker for AA AAA C D 9V CR2032 CR123A CR2 CRV3 2CR5 CRP2 1.5V/3V Button Cell Batteries

Excellent product, wish I'd found it years ago.

Works a treat

Very simple to use, good job as the manual is in Chinese ;0)Works well.

very good

Excellent little device

It takes most sizes of battery including some button cells but not D cells. Seems to give an accurate reading. Better than testers I have had previously.

This is brilliant for checking the life of batteries. It saves throwing batteries that still have some life in them.

This is better than I thought it would be. It is extremely light and feels at first hand that it is poor quality as it has 'brittle' type plastic however I was wrong and it works well. It is quick and very easy to use and checks a large range of battery types and sizes. It shows the range of power left in the battery. I was going to throw out about 10 batteries that still had a lot of power in because others I had put in appliances with them had low power so you think they are all dead. It saves a lot of time putting batteries in things knowing they work. As it stands at the moment I would recommend it.
