Mine is KW208. 1) It has no battery to install on itself. So I think it can measure partially dead battery since the tester will need some electricity. This might be a con to some one. On the other hand, this could be a plus since you do not have to worry about the tester itself. 2) This model has no upload option but it is not a big deal to a homeowner. In summary it works but you need to know your car battery type, CCA and the tester's functions.
This is a really useful tool and works well. I'd give it five stars but it comes with a seriously deficient user guide. This document leaves much unexplained and is so small that one needs a magnifying glass to read the tiny print that is there.
I just have this device for 2 days and cannot tell its accuracy. It is easy to operate. Manual should provide more details such as what SOH/SOC stand for and have to look up in the internet. The core should be longer so you can check the battery inside the car instead of running back and forth.
Easy to use, just follow prompts. Tested battery before going to dealership to have terminals cleaned. They confirmed "passed" verdict. I did not receive a bag, in other comments it said bag now included.
This product offers a lot for the money. I am disappointed in the user manual since it does not cover all the functions of the unit. You can figure this out on your own since it is menu driven. But you should not have to “figure it out on your own”
