Low SOC (State of Charge), the battery needs to recharge first and
then test again to confirm the actual results.
Volts : 12.55V(State of Charge [SOC])
The volts here indicated the State of Charge (SOC) of the tested battery which is 12.55V
during open circuit condition. [By referring to the table below, this battery is above50% SOC]

Battery Rating: 180 CCA
The battery capacity rated output is normally stated on the label for car batteries (either in
CCA, EN, DIN, JIS, etc.). For batteries with model numbers, please refer the charts provided
with the Analyser.
Power available: 120 CCA
It means that the battery tested has a capacity of 120 CCA power available. CCA ratings has
been used here, therefore the tested result is in CCA and if other rating (DIN, SAE, JIS, IEC,
CA, or EN) were selected, it will base on the respective rating to calculate and show the
results in that selected rating.
Please take Note:
This output value (120 CCA) is related to the actual power available in the battery in
relation to that battery's rating (180 CCA). On average, a new battery's CCA as
measured by this tester will read 10-15 % higher than its stated rating.
As the battery ages, the CCA number measured by this tester will decrease so it reads
near its rating. While this value is not the same as a CCA test, it is the best available
measurement for showing a battery's current condition in relation to its rating.
From the above example, a 180 CCA rated battery measuring 120 CCA available power
does not mean that the battery would pass a CCA test at 120 CCA. The available power
reading shows that the battery is not able to perform up to its rated ability (180 CCA).
In comparison to another battery when fully charged, the 180 CCA battery measuring
120 CCA is no stronger than a 100 CCA battery showing 100 CCA available power when
fully charged.
The available power number is meant for comparison to its own rating. In fact, in this
example the 180 CCA batterywas failing to perform to its rating, while the 100 CCA
battery is still working.
Basing on theSociety of AutomotiveEngineers (SAE) in America, CCA test is a
manufacturing process control test applicable only on new, fully charged batteries. It
does not produce an actual value, but is a PASS / FAIL test.
