Review: Good
Review: As winter is quickly approaching and car batteries are failing, I figured this was a good time to try a new battery tester. I have an old style toaster which does a great job of putting a load on a battery, but the toaster has its limitations. That’s where I found the BT500 is a great addition. I found it easy and intuitive to learn. I also appreciate the printed manual which clearly explains the operational modes. I tested multiple car, motorcycle and marine batteries and I found it to be quite accurate. By sculling through the display you can quickly perform a capacity check, then a cranking test and finally a charging test. Input the capacity of the battery I.e. 700 CCA and start the vehicle and it will show you the result. Another nice feature of the charging test is using the waveform option to monitor charging rates and starting voltage. The test results can also be saved and printed. Finally you can update the software with future upgrades. Over all I found it to be a great addition to my tool box.
