Instead of getting an OBD2 code reader and a separate Battery and charging system tester tool, why not saves some money and get 1 tool that does both? The Artilink 500B does full OBD II functions and also has some basic graphing functions which is not usually seen in cheap obd2 code readers. Quickly swap out the OBD cable for the battery cable and this tool is swiftly turned into a useful battery tester. It includes a battery test, starting test, and charging system test. great for confirming if your battery or charging system has a problem. In this video, I Fully test the Topdon AL500B Diagnostic tool to see what it can do, I share my final thoughts and findings at the end, I hope this video was helpful, and thanks for watching!

Note: It appears that it only does battery tests for 12-volt systems only but does the cranking and charging system tests for 12/24-volt systems. I find it strange that it's unable to do 24-volt battery tests. Unfortunately, I don't have a 24-volt system to test it out on.
