Tenergy T-333 BatteryTester

This is the best gadget!! I'm not sure why I didn't think of buying one before! The time it has saved me in checking the gazillion batteries I have for my LED candles! I don't have to keep rotating batteries and keeping them in case they have any juice left! This gadget just tells you what level it's at! I've tossed all the low level ones knowing they are done! Thank you!!

This battery tester is so easy to use and tests most battery sizes including button batteries. I wouldn't want to be without it. The Walmart price beat Amazon's price, considerably.

After using the Tenergy T333 Universal Battery Tester I can say that it's pretty good. It can test a whole bunch of different types of batteries including button cells. No buttons or knobs to set, just put the battery in the only hole that it will fit, and read the LCD screen, and that's it. It's really just plug and play. The only thing that could be improved is the LCD display, the display is hard to read sometimes.

Great battery testing tool. I use a lot of the small button batteries and my previous tester was difficult to use with sliding parts that never got a good contact. This is easy to use. Place the battery in the correct slot and done you get a reading every time. It is a good way to test batteries that are not used often to make sure they will be good when the need arises.

The battery tester is great. It's so easy to use and the screen tells you exactly how much is left in your battery.

I've had several battery testers before and none of them compare to the Tenergy battery tester. It is well designed and easy to use. Was well worth the money.

I have bought several of these for gifts, they are the best battery tester you can find. We use ours all the time and everyone we get one to appreciate them

I only marked it down slightly because the batteries sometimes need rotated to make good contact. It works great! Easy to read! I am very much loving the ease of knowing what batteries I have that do/don't work. It is good to know if I need to only replace one battery to run something that previously I would have wasted all the batteries thinking they were all worn out because the device stopped working. I happened to have some used up batteries laying on my desk... and more than half were not "dead" or "poor", just "weak" = they worked fine in a different device.

I enjoy that this battery tester allows you to insert the battery into a fixed slot for testing compared to the traditional testers in which you need to squeeze the battery between two prongs. That being said, I haven't used it much, but I tested batteries that were clearly drained and showed as "good" on the tester. I'll continue to use the tester hoping for better results.

perfect for checking batteries
