Dlyfull B2 電池チェッカー LCD表示 単1単2単3単4・9V対応 電池残量チェッカー

This is a great battery tester, easy to use and it tests a very wide variety of batteries. I find it very helpful when I am troubleshooting to quickly determine if the battery is the problem. I would prefer a battery tester that doesn't need a battery to function, but overall I am happy with this.

オタクのためペンライトを使うのですが電池がすぐに減って明るさが落ちるので、こまめに取り替えていたのですが、その中途半端な電池をどうしようかと思い購入しました。結果捨てようと思っていた電池の大半がまだ十分に使える状態だと表示されるので驚いています。リモコンなどの機器で使ってみようと思っていますがあまりに多いので、逆に本当にこのチェッカー大丈夫だろうか…とも思っています。

動作用電池がボタン電池でなく乾電池で動作することが良い。残量が通常3段階程度がリニアに近い表示のためわかりやすい

使いやすいとおもいます。

90歳手前の母がすぐに、使った電池と新品の電池を混ぜてわからなくしてしまうので、電池の形状別に嵌めて残量チェックをできる道具を探していました。 使わせてみた結果、表示の字が小さくて分からない、手もとが震えるので思うように嵌まらない、と…(苦笑) ですが、実家に帰る時に還暦の私が調べる分にはお役立ち神グッズです(笑)

以前に買ったものが寿命で液晶が点かなくなり買い換えました。 乾電池の容量が簡単に確認できるので便利です。

機器動作用の電池を入れるだけで測定可能となりお手軽でした。 充電池(エネループ)も試しに入れてみましたが、14/18目盛りで、 なかなかいいところをついているような感じでした。ですが、 AIに聞いてみると充電池は切れる少し前まで1.2V近くを保つそう なので寿命の判定には使えないとのことで、結局フル充電でき なくなるまで壊れているかどうかの判定にしか使えないようでした。 なので当初の目的通り、見覚えはあるけどいつ使ったか覚えてない 乾電池の余命の判定に使おうと思います。

とっても使いやすい商品で満足しています。強いて言えば、電池の残量の数字が表示されれば嬉しいのですが、この価格では無理だろうと思いました。大切に使いたいと思います。

After a recent move, my small battery tester gave up the ghost. I find these things to be very useful and being without one while decorating for Christmas was not optimal. For my battery-operated lights, I had to go through my battery drawer pulling out batteries and trying to find combinations (the lights require two or three AA each) that would work. Sometimes one of two batteries would be ok. Sometimes one of three was bad and prevented the other two from powering the lights. In fact, it was so tedious I went out and bought a giant pack of AA batteries at the local hardware store. When this device came in I immediately went back to the battery drawer and tested all of the remaining ones. Several had to be discarded because of either no charge or borderline. I've found that LEDs do not like batteries that do not deliver the full charge and all my Christmas lights are LEDs. As a plus, I had a bunch of older button batteries that, surprisingly, still hold a very good charge. I was thinking of pitching them, but now all I have to do is figure out what device I put them in. What I like about this device is that it tests a very wide range of batteries: your usual-suspect C, D, AA, AAA, and 9v of course. Also most 1.5v button batteries and even 3v button batteries; though larger ones like a CR2450 won't fit into one of the button sockets on the tester, you can check them by holding against the contacts on the 3v button slot. It also tests a range of the 3v cylindrical batteries used in my home security system. Nice. It even comes with a AAA battery to power the tester. Also nice. All-in-all a fine little device and well worth getting

Brilliant. Went through all my batteries and tested them quickly and easily.

I had loads of batteries of varying sizes and was convinced that they still had power left in them and needed a way to be sure rather than just chucking them away. I opted for this battery tester because it can test most battery sizes. When it arrived I was pleased to see that it was fairly sturdy and after looking it over I tried all of the old batteries and found that most had power still in them. Only a couple need binning. I had also mixed up some new batteries which after testing confirmed that they were still full. so saved throwing our perfectly good batteries. The only concern that I found was that some of the batteries showed more than half life but in reality performed poorly when reused. I was pleased to say that I did save about 10 2025/2032 coin batteries which I had no idea if they were still ok or not. In conclusion you could continue to just test in other items but I found this tested was good to test loads of batteries I had stored like many people do. Will I get the money paid for this back-probably not.

Hello! I've been using this battery tester for about a month, and it works really well. It was very easy to set up. Just take it out of the box, put in the included battery, and it's ready to use. To test a battery, just place it in the tester, and the screen instantly tells you if it's Poor, Weak, or Good (Excellent). The display is easy to read, and you get the results right away. I've used it on several different types of batteries, including rechargeable ones, and it has worked great every time. I've also compared this battery tester with another one just to check its accuracy, and the results were the same. It appears to be very accurate. Overall, this is a simple, useful tool that does exactly what it's supposed to do. I'm pretty happy with my purchase!

Works good, happy with item
