The Vdiagtool BR300 is a tester for 6-12v lead-acid batteries of different types. First off, it is easy to use, supposedly has 99.5% accuracy, looks and feels like a first-class tool, is f/w ungradable, and gives repeatable results. After a fair amount of testing on good and bad batteries, both large and very small, I am confident that the readings and results are accurate.I purchased this item because I was looking for a tester that would provide accurate battery information for small lead-acid batteries. The BT300 has this unusual capability due to the very wide range of CCA's. Once I figured out how to approach testing of these small batteries, the tester did the rest and I had confidence in the results, finally.The bonus for me is that the test results for large batteries when companied to other lead-acid battery testers were often very different from the BT300. After comparative testing on several larger batteries using several of my digital testers against each other and an expensive commercial tester, I'm now confident that my older digital testers should not be relied on for valid results and the BT300 provides accurate results. I did not expect such a wide variation in results for car batteries - I was wrong. I have now discarded the older digital testers in favor of the BT300.Sometimes the test results call for "replace," but the battery seems to perform as expected. In my cars and motorcycles, I never want to be in the situation where the tests reads "replace" yet the car starts normally, that is, until the outdoor temperature drops and the car just will not start due to known battery weakness issues. It's just not worth taking a chance as far as I'm concerned. The BT300 helps avoid this kind of issue, if used properly, and its data and readouts respected.On a related subject, I had some interaction with one of its customer service agents, Anna. I knew from the Amazon listing that Vdiagtool promised great customer service. She was perfect for my needs in all respects.You should have no reservations about purchasing the Vdiagtool BT300. I'm convinced Vdiatool will take care of any issue you may have upon receipt or during its lifetime without much effort on the part of the customer.Great product! Great customer service!
