Very impressed with this battery tester. You can use a test a huge variety of domestic batteries domestic and rechargeable batteries. Fits neatly in my tool box.

Such a wide choice could not make my mind up plumped for this one in the end, pleased with my purchase, works fine tested all the batteries out of Christmas decorations items, user instructions a but basic but soon discovered how to use it, clear display which show the battery capacity percentage as well as the voltage, the tester gave consistent readings for the same battery, 100% for new down to 5% for well used ones, worked on CR2032 cell batteries

Good, but can be a little temperamental, usually due to the internal batteries slipping away from the contacts. Meme sure they are in place before using and you are good to go.

Tests just about every battery there is!

I did not want to spend a lot of money on the ZBT mini tester so I decided to give this tester a go , which is still the most expensive tester I have bought to date by far ; I was expecting a reliable and versatile tester for this amount of money I held a battery steady on the contact and made repeat tests using the probe to check for consistency Results varied between 15% and 85% for the same battery over about 6 tests! I agree that this way of testing is awkward ; results seem to depend on where you touch the probe I was really hoping for better from this tester and am returning it

Quality item very pleased.

Great item, works fine, check video, when you press just once, it checks that each simbol on the screen is working,( battery indicator, charge %, voltage, and Err) if you keep pressing, it will check the batteries on the back of the reader, simple. for Li-ion batteries,use the 1.5 Alkaline checker

Excellent. Does what it should!
