Battery tester B2 Black

This tester works great. I bought it to replace a different tester that I was using. This tester is so easy to use. And I like how it can test so many different size batteries.

This Battery Tester is a must-have for quickly checking the charge on a wide range of batteries. The LCD display makes it easy to read, and it works with AA, AAA, 9V, button cells, and more. I love that it’s universal, so I can test multiple battery types around the house. It’s small, lightweight, and easy to use. The included AAA battery is a nice bonus. Overall, it’s a great tool to help prevent wasting batteries and ensures I’m only using fully charged ones.

Awesome little gadget, does the work well !

Simple and versatile battery tester. With prices going up for AA and AAA batteries, stop throwing away batteries that still have some life in them. This test mot all typical battery sizes, from AA to D, 9V, and many coin-style batteries. Easy-to-read bar graph at the top tells you how strong each one is. Deducted 1 star because the battery tester actually needs a battery to work properly. Seems this could be done without being powered (like the previous generation of testers).

It works as described. Well made. It will test any type of battery

This is the best battery tester on the market for the price. Very easy to use and accurate. Also, can read almost every battery you have, including the flat disc type. Highly recommend it, bought one for every family member.

Day 1: I'm impressed. My first impressions: This tester is a little smaller than I was expecting, but not inconveniently so. It is amazing how many sizes and types of batteries that this works on. Button batteries and even n size! I've had the type of tester that's common now, where you have to hold the tester in one hand, then place and hold the battery in it, with the other hand and somehow be able to slide the gage down to make solid contact with the upper terminal - no spring-hold on those ones. This unit has precisely fitted slots for each battery type. Very nice. It seems well made and is light. It had a high percentage of 5 star ratings and a sufficiently low percentage of 1 stars for me to give it a shot. The 1 star complaints were mostly about a random battery slot failing to work after the return period. I can't comment on that on day 1. The unit requires a single battery (provided) to power the screen, which only comes on when reading another battery's charge, so battery drain (another complaint, though infrequent) shouldn't be an issue. The manual is almost useless, though. It simply points out what each part of the unit does e.g. D batteries here, AAA batteries there, etc. So far, Top Marks for this product!

Simple, effective and very easy to store in my battery drawer.

Good quality and easy to use.

I have a number of battery-operated devices and like to take the battery out when not used over a period of time (previous bad experiences with leaked battery juice). This device works on all my battery types and I can tell in an instant which battery is good even though they are all mixed up in my battery storage compartment.

Perfect, does exactly as described. So handy.

I like that all the batteries you can test on this tester are easy to use. Fast delivery. I like it sooooo much
