The Launch Tech USA BST-860 Battery System Tester is designed for many battery-powered vehicles ranging from 12V to 24V like cars, boats, and motorcycles. It can perform six types of battery system tests which include ripple detection, battery test, electric current test, starter test, charging system test, and voltage test to find out the battery health status. The BST-860 will display the analysis result in a few seconds, which also can be printed out with the built-in printer. If any abnormal test results occur, expect a shortened service life-span or battery damage.
