Features and Benefits:
The B400 tests 12V heavy-duty auto, truck, commercial and marine batteries and 12/24/36 volt starter and charging systems. The B400 is easy to use since battery size is not required to be entered. Battery volts displays automatically when the tester is connected to the battery. Then simply choose between automotive or truck battery type batteries for testing and press the Test Button. This eliminates tester input errors and allows the testing of batteries of unknown size. LED Bar Graph immediately displays battery condition upon pressing the TEST button. The B400 features 4 ft heavy duty abrasion resistant cables for trucks and buses with hard to reach battery compartments.
