This good quality and very accurate tester is just about as sensitive as my multi meter. You can quickly check lots of common sized batteries for their charge level and remaining strength. it is accurate enough to see remaining amperage in otherwise fully charged batteries. This way, you can tell if a full battery that may have some use is strong enough to use in high demand applications. Or, you can relegate such batteries to light load/small draw uses like flashlights. this way, you can re-purpose some batteries that have less than full power which will save you $$.

Ot sure what some people are having trouble with, with this tester because I find it as easy to use as it can be. I gave it 4 stars because it’s a cheap plastic tester. I don’t think it would take much abuse but after all, it’s a battery tester not an anvil. I tested several types of batteries and knew ahead of time what their charge and condition were. I had used a friends very expensive unit to test them a few days earlier. I got virtually the same results from this tester so I’m very impressed with its accuracy. Just font bounce it around the house and I can’t see why it won’t last a long time. I’m Very happy and it is exactly as advertised. I do recommend it.

El probador hace muy bien su funcion y es ergonomico, el costo esta dentro de su calidad.

I bought this battery tester specifically to test 4 brand new D batteries I just purchased to use in a touchless trash can. The lid sensor stopped working after a year and a half so I replaced the batteries with 4 new ones. The sensor still didn't work and I was ready to toss the trash can out but then decided to buy this battery tester first. I didn't expect that 4 brand new copper top batteries would be the problem but it turns out they were! Two tested DOA and two tested very low. The batteries with the 10 year guarantee weren't even good for 10 minutes!Thanks to this battery tester I saved $$ by getting a refund for the bad batteries; I saved money by not having to buy a new kitchen trash can; and, equally important, I saved a big hunk of metal from ending up in the landfill.I then tested the old batteries that I had saved up to dispose of properly. Turns out some of them were still good. Think about it, when a remote stops working, most of us change both batteries which is wasteful. Now I can test the batteries and just change out the bad ones. The tester is easy to use but sometimes I have to play around with positioning the larger batteries.btw, I'm sure most of you know to recycle ALL batteries so that toxic chemicals such as cadmium, lead and lithium don't end up in our landfills and leach into our environment. Rechargeable batteries are more toxic but regular alkaline batteries are toxic too.12/22/22 over 2 years later and this still works like new! :)4/15/2024 still working!!

I am so glad I got this! 100% worth it! I went through my 'good' battery drawer and another box full batteries I thought were dead I was planning to take to recycling.I went through the 'good' box and was surprised to find several batteries were bad.Then I went through the 'take to recycling' box and I was shocked to find about 30 batteries that were still good!The batteries were bad when I threw them in there, so how the heck did they have power again?Well I googled this question "Why do batteries come back to life?".. and found and amazing answer on howstuffworks. If you want a technical explanation google that question. Here's my short non-technical summary:There are two reasons batteries that are still good may appear to be dead:1. If you are using several batteries in a device, only one of the batteries might go dead, but the device will stop working, when actually the other batteries are still fine. Without testing the batteries, you might assume they are all bad and throw them away. Which is part of the reason I found so many good batteries in my recycling bin!2. The second reason is pretty technical to describe. In simple terms, basically when batteries are powering a device, due to the reaction going on, the polarities can become 'blocked' and they appear to loose power. If you let them rest for a while, the internal reaction will dissipate and the batteries will work again. In other words batteries need to rest and they can often regain their charge on their own! Of course this doesn't always work, but it often can. I have never heard of that before, but am glad I know now. This is the second reason I found so many batteries I thought were dead, were actually still good! So next time your flash light goes dead, hold on to the batteries that test as bad. Check them again in a week and you might be surprised to find some of them are good again!I figure I'm not the only person who didn't know these things and hope this is helpful to someone else.So glad I can now test my batteries and actually know if they are really good or dead instead of guessing.This thing has already paid for itself several times over in one use by all the batteries I saved!Don't hesitate! I will be getting more of these and giving them to people who will appreciate geeky but useful gifts :)
