Thus, the CCA test shows the minimum power requirement for the
battery as rated, which means a battery rated at 400 CCA must
measure 7.2 volts or above for 30 seconds when a load of 400 amps
is applied at 0°F/ -18°C.
The above methods also hold for DIN, IEC, JIS, EN basing on its
individual ratings.
5.
Int. R (Internal Resistance):
6.72m
In normal condition, the internal resistance should fall between 2.0
m
~ 15.0 m
. As a matter of fact, the higher the battery CCA
readings obtained the lower the internal resistance should be.
6.
LIFE:
76 %
This is an indication of the battery life expectancy in percentage. If the
life falls below 45 %, the RESULT will display “Replace” and it is time to
change to a new battery.
Explanation of the following terms used as shown on the LCD display:
CCA (Cold Cranking Amps)
– most commonly used Standard.
CCA is a rating used in the battery industry to rate a battery’s ability to start
an engine in cold temperatures. This rating is the number of amperes that a
new fully charged battery can delivery at 0
F (-18
C) for 30 seconds, while
maintaining a voltage of at least 7.2 Volts for a 12V battery during cranking.
SAE (The Society of Automotive Engineers) Standard.
SAE has established Cold Cranking Amperes (CCA) rating for batteries as
their standard. Therefore this rating is the same as CCA rating as
mentioned above.
IEC (International Electrotechnical Commission) Standard.
IEC amperes rating require that at 0
F (-18
C), the number of amperes that
the 12V battery can deliver while maintaining a voltage of at least of 8.4
Volts for 60 seconds during cranking.
EN (European Norms) Standard.
EN amperes rating require that at 0
F (-18
C), the number of ampere that
the 12V battery can deliver while maintaining a voltage of at least 6.0 Volts
for 180 seconds during cranking.
JIS# (Japanese Industrial Standard)
JIS # amperes’ rating is based on Ampere Hours and is calculated using 20
hours rating. In this manual, it is using CCA ratings reference table list
provided basing on the JIS model number (See page 29 & 30).
DIN (Deutsches Industrie Normen)
Standard.
Basing on DIN , the rating requires that at 0
F (-18
C), the 12V battery is able
to deliver the number of amperes while maintaining a voltage of at least of 9.0
Volts for 30 seconds and 8.0 Volts for 150 seconds during cranking.
