"This crazy thing has gotten more use than all of the other Christmas presents combined. Not sure how I managed without it. So handy to double check those loose batteries before I throw them away, just to make sure they are dead. So far, all of them have been ALIVE.... good thing I had this, or I would have tossed them." - Lauren G., NE

We got one of these as a stocking stuffer and SERIOUSLY, this changed our lives. Who knows how much money we've wasted over the years on batteries when we could have just replaced one or two?! I test batteries just because it's fun now. Honestly, I don't know what we did with ourselves before we got this. We are simply charged up about it.
Finally got this great tool to save me disguarding batteries that still have life! And it is really handy if you have 2 batteries and you get them mixed up, which one was good and which one was bad! It happens! Must have for every home!

Super easy to use! I use a wildlife camera out back to record the squirrels and birds and when it showed the batteries were going low I was able to figure out it was only two of the eight batteries. Had I not had this I might have foolishly tossed out 8 batteries that we're still perfectly good! Wish I bought one of these long ago.
Very useful! Quick and easy to check the usual suspects in my remotes, mouse and whatever else use batteries. Especially handy if you ever grab one of those off brand 50 packs or whatever might be on sale. I usually have a bunch that die quickly and the rest do good. This helps to weed out the bad ones and helps to sort out a big batch of unknown status batteries. Love it!
Just plug the battery on it and the result shows on LCD screen instantly. It is easy to reading through. Energy bar tells how strong the battery is. The best part is that it compatible with any size of batteries and even watch battery. It just saved me a lot of time. Glad that I bought this!
I had three identical table top stereos with identical remotes. I was preparing to advertise them for sale and had just replaced all of the AA batteries with fresh ones out of a package. I couldn't figure out why one remote wouldn't work. Used this tester to determine that one of the brand new batteries was DOA - dead right out of the new package! This little tester is a real gem!
I used to always dispose of questionable batteries and this tester has saved me numerous times from tossing batteries that are still good. It's also a great first step when troubleshooting why remotes, mouse, smoke alarms, kids toys, etc... are not working. So happy I bought it!
I find myself using batteries more and more. Sometimes the good get mixed with the bad but this tester is an easy answer to that problem. I've been using flashlights and headlights that take AA and AAA batteries. I can now test them to see which ones are good and which need to be tossed. Great tester! I would recommend it to others and I would buy it again!
I can't believe I have not had one of these a long time ago. It can check a lot of different battery sizes and is super simple. I just recently checked a remote that I thought was not working. The battery was just low. I checked it and replaced it and the remote works awesome again. A must have!
I really like this battery tester! I really easy to use and works great. It came just on time for Christmas. So many things come with remotes including lights, decorations & toys to mention a few. I’m juggling dozens of batteries and sometimes old batteries get mixed up with new. Now when something suddenly doesn’t work I can check the battery charge. It’s very easy to use also.
I love this handy little gadget-- I tested all the batteries in the drawer of new ones, all the batteries in different devices, and suddenly realized there are batteries in my Swiffer floor mop, and that the fact the mop was not working was because the batteries were dead. This thing is essential for a functioning household!
I think THIS is the greatest thing since sliced bread. It brings me joy to be able to test batteries to see if they work or need to be thrown away (at the appropriate place of course). If I see a random battery in a random space I can check it! The small things that bring me joy.
Works great! I used this tester to test AAA, D, and 9V batteries so far. Instead of replacing my 9V batteries yearly, I used the tester that showed they were still good. This alone paid for the price of this tester. It's easy to use and as far as I can tell accurate. This is a great product. I highly recommend it.
