Dlyfull 電池チェッカー 乾電池 LCD液晶画面 バッテリーチェッカー 残量 チェッカー テスター 単1 単2 単3 単4 単5 9Vに対応 バッテリーテスター、1.5Ｖ/3Vボタン電池 CR123A CR2 CRV3 2CR5 CRP2 円筒形電池

【1】

期待通りでした使いやすいです

【2】

あらゆる種類の電池残量をチェック出来て便利だと思いますが、本体に電池が必要なのは少しシュールな気がします（笑）

【3】

コードタイプのチェッカーと比較すると、電池をセットするだけで計れるので素晴らしい商品だと思います。

【4】

電池がキレていないかを確認するのには良い商品、但し説明書が読めずGoogleレンズで確認しました

【5】

9Vトランジスタ電池の残量が分からず困っていました。あまり市場にないので今回購入出来てありがたかったです。コイン電池もチェックでき良いと思います。

【6】

非常に操作しやすいし，あらゆる電池に対応しているので使いやすいです。これ自体に電池が必要ですが，装備されているので別途用意する必要はありません。即使えます。

通常の単1~5の他にボタン電池等も測れるので購入してみた。が、家電のリモコンが動作しないほど消耗した電池でも「GOOD」と表示され、まるで信用できない。試みに測定する各端子間の抵抗を測ってみると、1.5V用（単1~単5とボタン用）が391kΩ、3V用が20kΩ、6V用が28kΩ、9V用が42kΩあって、測定の際にはmA以下しか流れていない。これでは実際の使用状態を倣っておらず、電池の消耗を測る事は出来ない。（アナログのテスターで電池の開放電圧を測っているようなもの）因みに20年くらい前の国内某社製の電池チェッカー（3LEDで表示するやつ）で同様の測定をしてみたら、1.5V用は11Ω、9V用は568Ωでそれぞれ130mA、16mA負荷を掛けていた。さて、どうしてくれようか。

このバッテリーチェッカーはかなり昔に購入して愛用していたお気に入りだったのですが、保管の不注意で使えなくなってしまいました。メーカー名も分からずにAmazonを検索したら、まさかの同一機種が現行品で販売されていることが分かりました。前はグレーでしたが、今回はブルーを注文しました。いろいろな種類の電池が難なく使える比類なきスグレモノで、「そうそうこれ！」という感じで早速使っています。

Okay, let me start by saying I'm not a scientist. I'm not into whether this tester is "under load" or "over load" or whatever those terms may mean. I know that amount of precision is important for some people. Understood.For me and what I do know is that this tester gave results that I expected. For batteries that I knew weren't working (because the flashlight or other item wasn't working), this tester indicated those batteries were DEAD. For new batteries that should be GOOD with a full charge, this tester showed GOOD/FULLY CHARGED every time. For some batteries that have been used in items for a while, the tester showed WEAK, or slightly less than full. To be expected. I tested batteries from Amazon and other retailers. Duracell, Energizer, etc. If the batteries were supposed to be new, this tester showed they were. If they were corroded, had been used for a long time, or were well past the use-by-date, the tester showed WEAK or DEAD.That's what I wanted. I did look at some of the testers that were in the under $10 range. I didn't like the way you had to hold button cell and CR2032 batteries to test them. They easily slid out of those testers if you didn't hold them just right. So, I spent around double the price for this tester using it to test literally every size of battery I had from 9V down to the smallest button coin batteries. I had over 20 LR44 and LR1154 batteries I use in my bike computers. This tester quickly showed me the weak batteries and the good batteries. I knew what they probably were based upon use and the date on the package. But this tester verified those readings.I also had some loose batteries that I literally did not know if they were good or bad. I put every one of those in the tester and wind up with many dead batteries, some okay ones, and many good ones. It was easy to toss out the ones that I couldn't trust in the future using this tester.I gave the tester 5 stars. If it lasts, it's worth 10 stars. Unless you need scientific precision using load/no load factors, this tester is awesome in my opinion. I will buy a second one to have when I invariably can't find this one. Highly recommended.

This is an excellent battery tester. Easy to use. The size is handy, not easy to misplace like a previous tester I had. It's functional, can be used for different size batteries plus button batteries. It is not to heavy and is accurate.

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.

Quite pricey for a battery tester that doesn't work as good as it claims. Average performance.

Great little gadget, know what batteries are good now
