Dlyfull Battery Tester, LCD Display Universal Battery Checker for AA AAA C D 9V CR2032 CR123A CR2 CRV3 2CR5 CRP2 1.5V/3V Button Cell Batteries, 1x AAA Batteries Included

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.

Pretty cool! Especially at this low price. I had a bunch of AAA batteries, some dead, some not, that motivated my purchase. It made them easy to sort into Keep/Discard. Same for some AA. Haven't tested all other sizes yet, but based on AAA and AA I can say that the device's "fit" to the battery is not "perfectly snug", may require a little jiggling to be sure if one is dead, but it does work.

This battery tester works well and is easy to use.

I was really surprised it's how many different types of batteries that I could check to see how good they were. Along with the typical AA,AAA,9 volt in several shorter batteries that were shaped like those but shorter and a little wider they check a variety of the round batteries. The size is small, but not so small I would lose it. I like the design and it seems very accurate. The only thing I do not like is that there is no on/off button to push so I don't know whether once it recognizes, there's no activity it's shut itself off or if it keeps going until the battery runs down! Until I solve this I just put the AAA battery in the spot that it would go if I was checking it and then put all of it in a baggie and if I want to check a battery, then I take it out and put that battery in the charge department. I did not find the instructions for that in English. At first, I thought the talk two buttons may have been it, but those are actually the charging indicator for the 9 V batteries. Overall, I'm actually really pleased with this as I can determine status of a lot of of the batteries in the "junk drawer" that the grandkids may have inadvertently dropped the old ones in when they picked out the new ones they needed. For the price I certainly recommend. !

Nice charger, works well

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.

I love this battery tester. It is the perfect size and of great accuracy. I purchased in the past different tester from Walmart and HomeGoods, but this one has fair better superiority. It is very easy to use and test

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!

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
