CA (Cranking Amperes) Rating.
This rating is the number of amperes that a new fully charged battery can
delivery at 32
F (0
C) for 30 seconds, while maintaining a voltage of at least
7.2 Volts for a 12V battery during cranking.
Unknown
If you are not sure which ratings (CCA, EN, IEC, JIS or DIN) that the battery is
based on, then choose this setting. It will show the battery
’s Voltage (State of
Charge), CCA and the Internal Resistance (m Ohm) only. This selection can
also be used to test 12V - Deep Cycle Batteries.
An example of the results display is shown below: (Fig.35)
To determine the condition of the tested Deep Cycle Batteries, refer the
Volts
reading
– State of Charge (
should not fall below 12.60V when fully
charged for Lead Acid Batteries, 12.85V for Gel Batteries and 12.80V for
AGM Batteries
) and the Internal Resistance [
Int. R
] of the tested battery
should
not be more 15 mOhm
readings.
Batteries that had been left idle for long periods can still be tested with this
analyser. To perform the test, just clamp the analyser clips onto the battery
terminals and it will display the screen (Fig.36) as shown if its voltage falls
below the normal 12.0 volts.
