Purchased this tester since I wasn't sure if I had a battery going bad in one of my vehicles. I lent my friend my other battery for a project but he was out of town at the time when I needed mine. I purchased this one after looking around for a few minutes. It was on my door step in a few hours after purchase.Likes-Bluetooth enabled for smart device set up. I have the app on my phone but I could also use it on my tablet if needed. The BT allowed me to record a history of my tests so I could go back and verify the issue.-Ease of use. Very easy to set up and use. The menus are laid out nicely.-Tests different system besides the battery. You can check your charging system or starter. Very useful. With a smart device, it makes it even easier. Great for working inside the vehicle.-Records your data from previous tests when using the app.ConsNone.Great tool. Easy to use. Plenty of data over an old school carbon pile or basic battery tester. Yes those are simple but it is nice to have a capture record when the tester actually shows.

I’ve been searching for a battery tester for a while. As a mechanic I’ve had my share of diagnostic equipment and my thing is find that’s reliable, user friendly, and have a great customer service history if any issues occur. Since I purchased the device I was able to check my vehicle battery health , Charging system, and even check with a load on the engine to see it’s performance. The tester was able to do so and I was even able to text the results to myself for future reference. I was even able to help my neighbor with his vehicle having a no start in the morning. I text him the results with the app also. I found his battery was bad and he needed a new one. With all that the price was a no brainer. Fare price for a great product. I recommend to have this product at your tool box or vehicle. Great product! I hope this helps.

I'd been borrowing my friend's profession battery tester (he's a mechanic), and finally decided to get something for myself. The reviews were good for the TopDon, but I wasn't sure what to expect. I tested a bunch of batteries I had in different vehicles, and here are my impressions. I powers up immediately where my buddies took a little bit to startup (his had a bunch of modules for customer information which I don't need). Both could test the battery, the ability for it to crank and engine, and whether they were being charged properly by the alternator. Both his and the TopDon came to similar conclusions about battery health for all batteries tested (a couple were weaker than I'd expected (but it's summer, and haven't had a need for high CCA. One of the batteries on a car that sits was almost dead, and the TopDon was able to at least read the voltage where the screen on the professional one just flickered without data since there wasn't enough juice to run the device. It's got an intuitive interface, and I was glad it could test both spiral and flat plate AGMs since I own both Optima (spiral) and Evertstart (flat) AGMs. Seems to work well and meets my needs, not a bad little tool for my kit.

I recently acquired the TOPDON BT100W 2-in-1 Car Battery Tester, and I must say it has been a useful tool for assessing the health and performance of car batteries. Here's my review of this product.Firstly, the 2-in-1 design is a major advantage. It combines the functionalities of a battery tester and an alternator tester, providing a comprehensive assessment of the charging and cranking system. This dual capability saves both time and money, as I no longer need to invest in separate tools for these purposes.The inclusion of Bluetooth connectivity is a notable feature. It allows for wireless communication between the tester and my smartphone via a dedicated app. The app provides detailed battery test results, including information on battery voltage, cold cranking amps (CCA), battery capacity, and more. This real-time data provides valuable insights into the battery's overall health and helps determine if it needs replacement or if there are other issues with the charging system.The battery library supported by the device is extensive, covering a wide range of automotive batteries. This ensures compatibility with various vehicle models and battery types, enhancing its usability.The build quality of the TOPDON BT100W is commendable. It feels robust and durable, capable of withstanding regular use in a garage or automotive workshop environment. The clear and intuitive interface of the tester simplifies the testing process, making it accessible even to those with limited technical expertise.One minor drawback is that the Bluetooth connection can sometimes be finicky, requiring a few attempts to establish a stable connection. However, once connected, the app provides accurate and detailed information about the battery's condition.Overall, the TOPDON BT100W 2-in-1 Car Battery Tester is a convenient and informative tool for anyone looking to assess the health of their car battery and alternator. The Bluetooth connectivity, extensive battery library, and comprehensive test results make it a valuable asset for both DIY car enthusiasts and professional mechanics.Disclosure: I received no incentives or compensation for writing this review and based it solely on my personal experience with the product.
