2Pcs Battery Tester for AA AAA C D 9V 1.5V Household Batteries

⭐⭐⭐⭐⭐ I am extremely happy with this purchase and would absolutely recommend it to others. From the moment I received it, I could tell that a lot of thought and attention went into the quality and design. It arrived exactly as described, was easy to use, and met all of my expectations. One thing that really stood out to me was how well-made and reliable it feels. I’ve been using it regularly and have had no issues so far. It performs exactly as intended and has made a noticeable difference in my day-to-day routine. I appreciate that it combines both functionality and convenience, which can be hard to find. Another positive is that it offers great value for the price. It’s clear that quality wasn’t sacrificed, and I feel like I got exactly what I paid for, if not more. The overall experience—from ordering to receiving and using the item—was smooth and hassle-free. I also appreciate the attention to detail. Small features that might seem minor actually make a big difference in the overall experience and show that the product was designed with the customer in mind. Overall, I am very satisfied with my purchase and would not hesitate to buy from this brand again. If you’re considering purchasing this item, I would definitely say it’s worth giving a try. It’s rare to find something that lives up to the hype, but this one certainly did.

These little gizmos work well. I am always wanting to know if a battery is good or not. Simple to use.

This is a good battery checker, but a couple of design tweaks would make it a fantastic, five-star tester. First, it really needs a built-in cradle to hold the battery securely in place while you slide the arm down to make contact. It is very difficult to hold the battery steady—especially smaller AAAs—during a test. While there is a groove for the slider to move down, it isn't wide enough to actually stabilize the battery. To solve this, I plan to make a small, removable DIY cradle myself. Second, the positive contact terminal needs a redesign. It currently features a sharp, pointed tip, which results in a frustrating "male-to-male" contact when trying to line it up with the positive tip of a battery. It should have a concave, female feature instead so the battery tip can securely nest inside. My fix for this will be to carefully file that sharp point off the positive terminal. On the plus side, the negative terminal works perfectly fine. If you don't mind a little DIY modification to make the contacts and battery placement more stable, it is a very useful tool. Overall - Very solid with a very good price.

I bought these because the duo pack was slightly more expensive than the single ones. If you use batteries in anything a battery tester is a useful thing to have. These battery testers work great. You just need to make sure you face the battery the right way and make a good connection. Works for regular or rechargable batteries. I have a special charger that can charge regular batteries. It really does worm unless the battery is deader that a doornail. Remote batteries are usually in a good state. They never go down to empty before needing to be changed. Those are perfect for the charger. So I use this to tell me which ones are ready to charge and which batteries are totally dead as they won't charge. I never looked for a regular battery charger here. I got mine from popular Mechanics. I think of it like this. If I only get let's say one good charge I've doubled my money. Most regular batteries will take several charges even the cheap ones.

Great Bargain. The meter connects and reads battery instantly. Analog display means no batteries to replace. It’s easy to use, fits multiple different battery sizes, and the display is very straightforward.

From what I can tell they work. I took several batteries and checked them on both testers. In most cases they tested out almost the same. I then compared them to another battery tester I have been using for years and they came out fairly close, sometimes reading "lower" than the tester I have been using for years, suggesting the battery may have less juice than what my older test indicated. I did not do any testing of these with a volt/ohm meter. I have done that in the past with my tried and true older tester. Yes, that would have been a much better test, but for the price of these testers and what I need them for, I just didn't take the time. Why only 3 stars? These are extremely light weight plastic. I found this to be somewhat of an issue. It seemed to make it more difficult to handle. To measure the battery, you have to adjust the plastic slide that has a connector on it. Then you need to put pressure on the slide with the battery in between the slide connector and the top connector to make a connection. Then the meter will register. BUT, you have to keep the battery in place and often it slides around between the connectors, so the connection is broken. With a little practice I got better. This is where I think a little more weight would be better. I think that would help to handle the tester when trying to balance the battery between the slide connector and the top connector. Just my thoughts. Would I buy again, for the price they will do what I need them to do; keep them near where I store my batteries to check when needed. I like that they come in the two pack. I like being able to test the batteries using both to do a double check. I would be very concerned if I was using these daily and in a garage environment. I worry about placing them somewhere that they may have stuff placed on them, e.g., a junk drawer. I also worry about dropping them. Again, if I dropped one, I like that I have a backup to check to see if the other one still works and just as a backup, but I would be concerned that they might chip or even shatter. So concerns about functionality. I feel okay with accuracy. Not too hard to read as long as I have my glasses on. Will update later if needed.

This is a simple device that quickly shows if a battery is strong or weak or dead. You get two testers in a package, which is useful.

This is exactly what I wanted. We have been using and loving 2 of the battery storage units from Amazon that came with this battery tester, much easier than hauling out your multimeter. One of the testers went bad so I just wanted one exactly like it (no battery required and very versatile) si that it would fit in the nook that was provided for it. Worked and fit perfectly and because it was a two-pack but we only had one go down, we now have a spare for the future.

Good quality and delivered as expected

Good product

Me gusta su calidad, pero es un poco difícil colocar las pilas para su evaluación

The product is simple and works reliably.

Seller send a non functioning product. Although quick to refund but should make an effort to check product before shipping out. Wasted time and effort on both parties.
