Review: Saves money when you have a lot of vehicle/lawn equipment batteries - Simple to use and gets the job done. Wanted something that was not overpriced, with good features and the ability to test a variety of batteries, alternator, and starter condition. After using this on several vehicles and batteries I have learned how the resistance of the battery and expected life of battery work. The feature for running voltage and ripple current graph have become very handy during load test. The starter crank test and time have helped find two starters that needed to be replaced. The screen is easy to read, menu functions are simple to navigate, and battery clamps / wire are of good quality.
Review: Great battery tester - Works as it should, and you don't need batteries!

### ⭐⭐⭐⭐⭐ Great battery tester
*by H***R on December 23, 2025*

Works as it should, and you don't need batteries!

### ⭐⭐⭐⭐ It provides useful data but it needs some work to be a polished product.
*by S***E on June 25, 2019*

I followed the directions and downloaded the "BTlink" software off their website. Since it was a .ra file I had to load a unzip tool to get the software unzipped. WIndows had security cows while trying to load Konnwei's software and after doing so I ran a couple of virus/worm scans and it appears to have not loaded anything detrimental onto my computer. The software then said to push the "OK" key while connecting the USB cable to the tester to get it to go into "Update Mode". There is no "OK" key on the battery load tester so I guessed that by pressing "Enter" would get me where I needed to be and it did. I ran a battery of tests on my battery. I wanted to do the quick test but it requires that you know how many Amp-Hours your battery has, not cold cranking amps. Most flooded car batteries do not have Amp-Hour ratings on the battery and thus I could not do the quick test. I ran the in-car tests which tested the battery "in-the-car" and gave the results as shown above. I also ran the charging test which showed the alternator charging the battery showing a small trickle charge voltage. I did the starting test which is captured in the waveform above which I turned off the engine and started it back up. The downward spike is the drop in voltage as the starter is starting the vehicle. With the BTlink sofware you are able to download the two items shown above. It would be nice to have them together on one page instead of printing two. The waveform did not print and must be saved as a bitmap first and then can be printed. This is done with the tiny icon up in the upper right hand side of the page. The book may describe this, but it should be listed in the software. or the icon a heck of a lot bigger. I liked that the trickle charge could be seen in real time, but it was not saved nor could be printed out. It would be nice to have that information so as time goes forward it might help indicate that the alternator brushes are wearing out. I also like the waveform that was being save in real time. I gave it four stars because there are somethings that would of made my experience better if the tester could quick test using CCA and update the BTlink software to not be "OK" but "Enter". What is it with the green in the test printout. Black would be better. I do like that the information can be printed for further reference. For the price it will be a nice addition to my garage.
