Car / Truck Battery Test:
This test is intended for 12V Batteries but not on 24V. The reason is most trucks that
use 24V systems have two 12V batteries connected in series to produce 24V. To test
on 24V system (12V Battery x 2), disconnects the connection between each battery
and test one battery at a time.
The test results of individual battery is more accurate than testing two batteries at
once due to the unwanted resistance created by the cable joining of the first battery to
the second battery that make 24V. So the battery test is catered for all 12V Batteries
only.
Performing Battery Test whilst it is still in the car or truck:
Vehicle that was running has to have its engine OFF first and then switch ON the
headlights for 30 seconds to remove the surface charge. After the headlights had
switched OFF, let the battery rest for at least 1 minute to recover before testing
commences.
The car or truck engine and all other accessory loads must be OFF during test in
order to have accurate results. When attaching the analyser clips, make sure that
the battery posts were not oxidized or badly corroded. Clean them first before
clamping to it. Do not clamp onto the steel bolts directly which may give inaccurate
and inconsistent results.
If the red and black clips were accidentally clamped directly on to the 24V output
terminals of the battery while testing truck batteries, the Analyser display will show
(Fig.11 and Fig.12) as below:

key for about 3 seconds and a long beep sound will be
