Car Battery Tester 6V 12V 24V VDIAGTOOL BT500, 5-3000 CCA Battery Load Tester, Starter Alternator Tester Automotive Charging Cranking System Analyzer for Car Truck Motorcycle SUV ATV Boat

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.

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.

This is a great tool to have in your bag to quickly diagnose the state of your battery which I have used on multiples cars. Quality battery clamps with alligator teeth on one side for good grip and a good length cable. There is even a quick test button, one click to instantly get a reading on your battery. This is super handy to grab a quick state of health on your battery and the feature I use most of the time. The display is very bright and easy to read at most angles. In addition it has an LED indicator for a quick visual of Good (green), Charge (yellow), or Poor (red). In addition you can go into the vehicle mode to do additional tests such as Battery test, Cranking test, and Charging test. Just follow the steps on the screen and it easily walks you through the process. The Battery test will give you detailed information on the State of health as well as the State of charge. In addition it will show you current voltage as well as the cold cranking amps compared to the factory standard on your battery. The results are given as to whether the battery is good, good but needs charging, replace, bad cell, or charge retest. Glad I had this tool because it let me know that my truck battery is failing and says replace, which keeps me prepared! The Cranking test will show you detailed data when you crank the car following the prompt but mostly you are looking for Normal or Low for the result. The Charging test is a little hard depending on your battery placement since you have to rev the engine but I was able to do it by myself with one of my cars. I do not have a motor cycle so was not able to test that feature but I am sure it will be helpful to those where that is a part of their fleet. You can do both in vehicle and out is vehicle battery testing which is helpful. The waveform feature gives you a graph display of visual dips in the ignition and charging states as well as offering a quick button for this feature as well. Additional features that come with this device are system screen test and button test as well as a easy to read manual. Provides easy review of recent battery test and wave form data as well as printing the results if maybe you need to give it to a neighbor. Plus it gives you a usb port for updating the software on the unit for feature improvements. Great Tool to prevent you from not being aware of a failing battery and leaving yourself stranded. The is also a Great company with exceptional support and quick to get back to you if you have any issues or need help! Highly recommend!!

Tried this head to head with a TopDon T100 and this unit has more functions, better screen, software is upgradable (I already updated it), and it seems to more accurately measure the 5 batteries I’ve measured with it. Oh, and it’s cheaper than the TopDon. Negatives: the jaws are just ok. Not heavy duty and I would trust it to be strong enough to be used daily at a shop. For the 10 vehicle batteries I need to stay on top of, this is perfect. I returned the TopDon I’ll update my grading after I take it to a few auto parts places and Walmart to test brand new batteries. I plan to compare it to the Autel ones many of the auto shops use.

Good

Works good

Je l'ai acheté pour m'est batteries a décharge profonde de camper power safe SBS 190F et il a pas la fonction que je voulais dessus me prend la fonction SBS ...Stationary batteries service

I'm not sure why they've listed this device as being 6v capable as it doesn't even have the option.
