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.
