The result indicates the battery is good and full of 100% of life. But only
12.11V left. SO suggest charging.
★ Life check OK, and voltage check over low
The result indicates the battery is OK and remains 73% of life. But only
11.88V left and over low voltage, which can affect the result. At this time it is
better to charge prior to checking again.
5-3 engine system activation load test
5-3-1preparation
If the engine is working, please turn off first and switch the key to off
location.
5-3-2 procedure of operation
(1) Connect the red clamp to the positive polar of the battery, and the black
one to the negative polar. Make sure they are well connected in order to avoid
affected result.
(2) Press <▲><▼>to select activation load test as the picture below:
(3) After selecting the test item, press <ENTER> to display the activation load
test screen as the picture below:

6-2 Can it be affected by the installation of negative current
inside the vehicle?
All the negative currency will affect the result. Therefor please remove
the negative currency prior to checking, in order to achieve the accurate
data.
6-3 Can this tester predict when does the battery become
useless?
The internal resistance of the sealed lead-acid battery is complicated. It
is generated by ohm internal resistance, concentration polarization internal
resistance, chemical reactions internal resistance and interference effect
caused by double capacitance's charging. The ingredient of internal
resistance and its relative content will change with different test method and
different test moment, which can lead to different tested value of the internal
resistance. And there is no strict relationship between internal resistance (or
conductance) and capacitance of the sealed lead-acid battery. So it is
impossible to predict the life of battery according to a single battery's internal
resistance. But it can be predicted the life of the battery will be over soon
from the sudden increase of its internal resistance and decrease of its
conductance.
6-4 Is the CCA value tested by this tester correct?
CCA is looked as a control standard with the produce of the battery.
According to the accumulated records, the tested value of new battery is 10-
15% higher than the standard value, and along with consuming of the battery,
the value is getting close to standard, even lower afterward.
6-5 What is the difference between the method of this tester
and the load test method?
