3.7 24V System Test
An ordinary 24V battery group combines two 12V batteries in a series connection.
Therefore, when testing a 24V battery, the tester will prompt “24V Battery”, divide
the batteries and test one by one. It’s not necessary to break off the connection
cable (Comparatively, the parallel connected battery group must cut off the cathode
connection), the test method is the same as testing a single 12V battery.
For 24V charging and cranking tests, connect the red clamp to the anode of the 24V
battery group and the black clamp to the cathode of the 24V battery group.
NOTE: It’s nott he anode and cathode of the single battery but the battery group), select
IN-VEHICLE, screen displays “24V Battery”, ignore the prompt, after 3 seconds, the
tester will skip the battery test program and enter the cranking test. Follow the method
of a 12V system test to complete the 24V charging and cranking tests. The test process
is same as with a12V system.
