Car Battery Tester TOPDON BT50, 12V Battery Load Tester, 100-2000 CCA Automotive Alternator Tester Digital Battery Analyzer Charging Cranking System for Car Truck Motorcycle ATV SUV Boat Yacht

Works and does its job, perfect and affordable little tool to add to my tool chest. I am a DYI proponent and have been learning a few things here and there. My car’s battery kept dying (car that I don’t drive daily), when I drive it regularly, the battery was OK, but died if I didn’t drive it for a few days. This tool diagnosed the issue with the old battery and I replaced it. Had a. We battery in storage for a few months, charged it and it was diagnosed as a good battery.

Outstanding! It tells you everything that you need to know about your battery In one simple step. And this is what sold me...at the end of its testing sequence (which doesn't take long at all),it tells a positive yes or no if the battery is good or bad. Nice!

I swapped out the battery on our 2012 Chrysler 200. Battery uninstalled was 12.2 volts and only 339 CCA out of a rated 550 CCA.New battery 12.2 volts, 559 CCA. 40 years of automotive here. I own an Autel scanner. I could've purchased the battery attachment for Autel scanner, which is Bluetooth. But it was $175.00 For the money, ease of use, you can't beat this thing. No, getting out my scanner, no pairing up (Bluetooth) hook it to the terminals and you're good to go, easy Peezy, reliable.

Hi, I only have this a couple of days so far so good as far as the battery test goes, seems to be close enough to what my multimeter voltage readings say. I've been charging my battery and testing as I go with TOPDON BT50 and my meter ,so far voltage readings are close enough with both. I haven't been able to do the crank /charging tests as my battery isn't hooked up to my car, because I'm still charging up my battery with a charger so I'm only able to do the battery test, these other tests will come later on and I'll update when battery is back in car. As far as ease of use, this gadget is so easy to use you could do without the small manual. As of now, I can say I recommend it, very handy and seems to work great ,only gave 4 stars because I wasn't ready to run the other tests due to battery not being in car. I will update.

Very impressed. I’ve got the Snapon but I use the Topdon more because it’s quick and small. The Snapon will provide more data when used with amp clamp but most times I just need a quick check of a battery

Easy to use and appears to be accurate.

Very simple to use, tells me strength of the battery and can get a sense how soon I will need to replace. Also tell me how effective my battery charger is in regenerating mode in restoring health of the battery.

It is a very good product and is exactly as described

日本語表示も可能だが表示がわかり難く使いずらい。英語表記のままで使った方がスムースに操作できる。

Easy to use and works great.

Great little unit for testing batteries , Highly recommend

車のバッテリー状態を詳しく知りたくて購入しましたが、本当に満足しています。 測定は数秒で終わり、電圧だけでなくSOH（健康状態）、SOC（充電状態）、CCA（始動性能）、内部抵抗まで数値で表示してくれるので、「交換が必要かどうか」を客観的に判断できるようになりました。 購入前に上位機種の「BT100」と迷いましたが、日常点検やメンテナンス用途ならBT50で十分すぎるほどの機能です。コンパクトで扱いやすく、コスパも抜群です。 操作についても、ボタンが少なくて不安になるかもしれませんが、画面に出てくる選択肢を順番に選んでいくだけなので非常に簡単です。むしろボタンが少ないのは、操作が直感的である証拠だと感じました。 日本語表示には対応していませんが全く問題ありません。表示はシンプルな英語だけで構成されており、変な翻訳よりよほど分かりやすいですし、付属マニュアルは日本語でしっかり説明されています。また、YouTubeには海外ユーザーの解説動画も複数あり、英語が苦手でも2〜3回見返せばすぐに使い方が理解できます。 クリップ部分もしっかりした造りで、しっかりとバッテリー端子を挟んでくれます。剛性も十分で安心感があり、ケーブルも適度な太さがあって頼りない印象は一切ありません。全体的にチープな感じがなく、長く使えそうな製品です。 この価格でこれだけ詳細な診断ができ、操作も簡単、作りも安心感があるというのは本当に素晴らしいと思います。 バッテリーテスターはいろいろありますが、これはいいと思いますよ。

使い方は簡単で繋ぐだけ。 一応、国産、定番輸入車、アイドリングストップ迄対応みたい。 仕事や出張に重宝してます。 説明書も日本語あり、本体も日本語設定できたけど⋯ 印刷機能があれば星５かな
