not mean the vehicles or batteries are faulty. For detailed faults, other special
equipments are needed. To validate the accuracy of the value, the best method
is to collect the signals of starting and charging voltage and observe it on an
oscillometer.
Generally, the voltage is lower than 11V for the bad cell battery, but it is possible
that the battery is completely exhausted or has a serious low capacity. In this
case, just recharge your battery. Bad cell always happens when the loads on a
stopping vehicle are turned on for a long time.
Please note that it is normal for quick detecting of “Increase speed” because it
follows the theory of detecting “Increase speed”: If the detected voltage is higher
than the previous battery test voltage, the system will prompt you a message of
“Engine has been speeded”
It has no influence on test result in the event that engine’s output voltage or
engine revolution is not very stable. No matter whether the vehicle is accelerated
or not, the output voltage only differs within 0.2V.
While doing inside the vehicle test, Kelvin clip is always found to be in poor
contact. To remain it in good contact, please shake it several times before
testing. Take down the battery connector, and test it again, the value probably
varies. The deviation may arise from battery connector.
Pay more attention to connect the clip. The battery poles connect with conductor,
which makes the clip has a poor connection when testing battery. A tolerance of
dozens of CCA occurs if the clip is out of position, or oil, dust attaches on the
pole. The gear and main body of clip should be fully matched with battery poles.
Notes:
1.
Battery poles inside the vehicle are enveloped by connectors, which may produce
some errors for test results. The tolerance results from the resistance of connectors.
The greater the resistance value is, the greater the tolerance becomes. But generally,
the tolerance does not affect the test conclusion.
2.
Testing the battery separately generates an exact test result. The battery box is a
very useful auxiliary tool for quick test. If any problems were found, test it
separately for getting an exact test result.
