Understanding CCA
1. CCA (Cold Cranking Amp) values are marked
on the battery casing. The CCA rating
defines how many amps the battery can
deliver at 0° F continuously for 30 seconds
before the voltage drops to 7.2 VDC.
2. Temperature strongly affects battery performance.
As temperature goes down, the energy production
of the battery is reduced, and the amount of
energy required to start a vehicle is increased.

32° F 0.0° C 65% 165%
0° F -17.8° C 40% 250%
-20° F -28.9° C 25% 350%
3. A higher CCA rated battery is
desirable in colder climates.
Battery Test
Tester is designed with an intuitive
step-by step walk through menu and selection
to perform the preferred testing criteria. Follow
instructions on screen to complete the test.
IMPORTANT: For testing 12 volt batteries
only. Suggested operational range 32°F (0°C)
to 122°F (50°C) ambient air temperature.
Save Test Data
The tester is capable of storing up to 10 test records. User can choose to save the test data for
later review. User can access and manage the test records from the tester Main Menu.
