Car Battery Tester 12v, TOPDON Wireless Battery Load Tester 100-2000 CCA, BTMobile PRO Battery Monitor Cranking & Charging Tester Automotive Battery Analyzer, Bluetooth Alternator Load Tester

Topdon sent it quickly and I have had it for a few weeks now.So upon opening the box, I was happy to find a semi-hard case to protect the tool. Unzipping the case, you can see that the tool is pretty simple. It has a power and ground lead, which will be connected tot he battery being tested. The alligator clamps appear to be very well made, unlike some other testers I have used. They are spring loaded and quite strong to hold and make a good, solid connection.Instructions are easy to follow as well. So, you download the app from the app store to either a phone or android tablet. You can then go through initial registration and such of the tool. (Simple to do)As for the tool in use, it is simple as well. The instructions are in the app once it is opened. You can save your results of tests, which I like because it can then be shown to a customer. I am used to using a midtronics tester, but have grown to really like using a picoscope for this purpose. However, this tool seems accurate according to the testing I have done thus far. Now, here's the thing. The midtronics unit was around a grand, the picoscope...well, that's obviously more. This thing..well, this thing is extremely cheap and realistically will give you the results you need to test your battery and charging system. It works as designed. Follow the on screen instructions in the app, for the test you are performing, and get accurate results. Not much else to say. It is a nice tool that works as advertised in my opinion.

The build quality of the tool is great, I can tell TopDon is using high quality plastics. The cables and claps were also a plus too.The whole tester came in a nice hardshell case, that was very easy to put away when finished.The reason why i knocked the product down so hard is because Apple Store and Google Play Store will not support TOPDON apps.Why did this happen:Apple and Google overhauled the app store requirements. Apps have to support software requirements, pass "debug" mode, pass a third party audit, and not crash. Additionally the the APPS must follow all the "privacy guidelines" so the app does not brick your mobile device.Topdon posted a YouTube video with instructions to download Apple's "Test Flight" app and install the Topdon app outside the Apple App Store. According to Apple, "Test Flight" apps should only be used for experienced users on a dedicated device that has no personal information on it.I did use a spare ipad and download the app, and the app did not work.Topdon app is not on the Google Play store either and I had to download the APK software (APP) from a mirror site (untrusted) and sideload it onto my Android Tablet.The battery tester worked once and I never got it to work again.When the Topdon app returns to the Apple store and the Google play store I will update me review.As it stands buyer beware.

Topdon shipped very quickly and it’s a great product very impressed that it came with a case and the app is very user friendly. I love how you can view the information as a graph and very impressed that it also does 24volt. First battery I used it on was a 24v for a case loader and it worked perfect. I’ve also used it on about 15 Mack Dump trucks so far and It has been very accurate. Would recommend to everyone.

Recieved tool very quickly, immediately took it out to use. Battery Tester comes in a very nice carrying case, very compact and professional.Downloaded the app quickly and easily, Bluetooth connects almost instantly upon connection to battery.User interface is very simple and easy to use. Test are completed quickly and a very clear and detailed report is given through the app.I look forward to using more TopDon tools.

I purchased the pro model to get the advertised battery database not included in the lesser model.After putting the Android app on my cracked for the Android play store apps Kindle Fire HD I fired it all up. Got the Bluetooth working and began reading a two year old car battery. First pass said it was marginal and may need replacing. Second and third pass showed it was in better condition.No help as to all the coded settings you need to know (like CCW - cold cranking amps) to enter prior to checking your particular battery. The help function is basically a link to a product advertisement. When I tried to enter my vehicle battery to get the database of data online it crashed out on the third piece of data I needed to enter and sent me back to the beginning. No response from their email customer support.It may be a great product, but not for me. I sent it back and went looking for a more reliable product.July 29, 2023 Update:Their customer support contacted me via email very apologetic for my problems. They asked for several details and screen shots to resolve the problems. I notified them that I had already sent it back.
