ZTS MBT-LA2 - Manual (Page 4)

Note: There are four different 6V and 12V MODES and
two 8V MODE options depending on battery capacity.
Choose the MODE which corresponds to the battery
being tested.
2) Connect the test leads securely to the battery’s
terminals. Verify that the red test lead is con-
nected to battery positive (+) and black to battery
negative (-).
3) Press the TEST button once. All display LEDs should
‘run’ for 15 seconds indicating a pulse load test in
progress. Next, a single LED will remain lighted
indicating the battery’s state of charge, or remaining
capacity. Make 2-3 tests to verify that the battery
has stabilized and is delivering consistent power
(especially if the battery is tested directly after be-
ing disconnected from a charger).
Understanding Test Results
The following are guidelines for correlating test results
to overall battery condition:
1) A battery which repeatedly tests 80% or higher is
nearly fully charged and is in good condition. Batter-
ies that are tested directly after being disconnected
from float charge should test 80% or greater for 2-3
consecutive tests. A test result of 60% or lower
indicates a failing battery.
