HT2018B(C) Battery System Tester 7
5.2.3 Battery test results instruction
1) The normal test result
Battery voltage 12.85V
Full power 100% 12.78V
75% 12.54V
50% 12.30V
25% 12.12V
Fully discharged 11.94V
CCA value 588CCA
◆ The test to determine the state of the battery.
◆ When testing 24V battery, CCA is 1/2 of the sum of the two 12V batteries in
series.
Internal resistance 4.75mΩ
◆ The battery CCA value is greater, the resistance will be smaller in general.
◆ The internal resistance of the standard is different because of different
materials battery, so there is no certain standard. But the same type of
battery with the same manufacturer does not differ greatly in resistance out
of the factory.
◆ When testing 24V battery, the internal resistance is the resistance sum of
the two 12V batteries in series.
Life Show the usage state of the battery. It is recommended to replace the battery
when the life of the battery is less than 45%.
