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.
7. 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”
8. 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.
9. 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.
10. 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.
