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.

I bought this to check my batteries before winter. I can’t afford to replace a good battery and I don’t want to get stuck in the cold with a bad one. The BT500 comes neatly packaged. The manual has clearly worded instructions on how to use the BT500. The BY500 screen is large enough for all the information that will be displayed, bright enough to see in bright sunlight. Using the BT500 is as easy as selecting the test you want to run and following the on screen prompts. I tested my wife’s 5 year old battery and it was in great condition. While I had the BT500 connected I went ahead and tested her car's starter and charging system. Everything tested fine. I had been worried about this battery because of its age but it looks like it should be fine for this winter. It is nice to have a tool that is capable of running multiple types of tests. That feature in itself adds to the value of the BT500. The design is straightforward and easy to use. A USB cable comes with the BT500 so you can connect to your computer and print your test results if you wish. All in all this would be a great addition to your toolbox, because it has been for me. If I were to offer any suggestions for improving the BT500, the only thing I would suggest is to make the cables longer. Testing the charging system requires increasing engine RPM and maintaining a set level for the test. I was able to do this alone on my Versa with the battery close to the driver side firewall. The same test on my pickup requires two people, or jumper cables to extend the reach. Like I said just a suggestion to take care of an easy to work around inconvenience. All in all a good tool and definitely worth having.
