Battery Monitor TOPDON Car Battery Tester 12V, Bluetooth Voltmeter Wireless Automotive Alternator Load Tester, Battery Analyzer Charging Cranking Tester for Car Truck Motorcycle ATV

You can’t get the App to use this thing. I spent two hours trying to figure it out then my wife looked up how to find the app and download it.It did work good after jumping thru hoops to find the beta app. This should be plainly told to people in the description. I was going to return it but decided not to.

Apparently, the BT Mobile App is temporarily or permanently gone from the Apple App Store making this device un-useable on an Apple IOS device. A shame because they claim it will work on Apple devices.UPDATE: Tech Support is fantastic. They explained the Apple App was updated and under a brief review by Apple. TOPDON supplied the information necessary to upload an approved version with the updated, under review version, to be available later.Long story short, the battery analyzer works amazingly well. I have tested and retested around 50 automotive batteries and find this device to be consistent, accurate, dependable, and extremely compact and useful.I now rate this tester at the 5 stars it deserves.

元気なうちにバッテリー放電量を知っておきたかったというのが購入動機です。CCAの他にクランキングテストとか充電量テストなんてのもできます。バッテリーの標準CCA数値はネット検索するとすぐに見つかります。CCAだけだと他にお安いのもあるのですがスマホとブルートゥースで繋いでモニターに出来るのが興味を引いてこれにしました。計測後はスクリーンショットかメニューの共有を選べば記録が楽ですよね。そんなに使うものではないので小さいというのも魅力です。表示部分があると保管中？（放り込み中が正しい）に傷がついていたりして残念なのでこれは良いです。基本となるクリップとか配線がしっかりしていて信頼できるかな？大電流計測なのにその辺がコストダウンしている機器はどうなんでしょうね、

Easy setup and straightforward app, can be used right out of the box, I do a lot of my own work, just a home mechanic and feel that this could be used by someone with just basic skills.Like the heavy duty clamps and it feels well constructed.it confirmed my suspicions that my motorcycle battery was on the way out after 5 years(recommend DEKA batteries!).Was able to get a new Yuasa battery(another good brand) thru Amazon as a new return that had never been activated, at a very good price, and installed it prior to my departure!Next up I will be checking SUV battery, it is about 4 years old.Was disappointed to see that mine did not come with the formed case, that others had mentioned, not even a carry bag.

スマホ用のアプリをダウンロードするだけで結果がすぐにスマホに表示され、共有可能とても簡単に各種テストが可能です。（私はCCA値の測定メインです）
