terminal clamps (7) for proper connection.
Check whether the terminals of the car battery are oxidized or
dirty, as such could affect the contact with the terminal clamps of
the battery tester.
a) Battery load test
This test analyzes the cold start ability of the battery. For testing, the tester
draws current from the battery while measuring the voltage. The voltage of
a good battery remains mostly stable. A defective battery will show a high
loss of voltage. Battery size and temperature affect the testing result. For
that reason, follow the instructions below.
1. Turn off the engine and any appliances connected to your vehicle. Very
small appliances, such as car watches, do not have to be disconnected
from the power supply.
2. Connect the terminal clamps (7) to your car battery. Connect the red
positive clamp to the positive terminal of the car battery first and then
connect the black negative clamp to the negative terminal. Ensure a
secure connection of the terminal clamps.
3. Check the cold start current of your battery in CCA (cold cranking
ampere). This value is usually printed on the battery. If the value is
not printed on the battery, contact your dealer/manufacturer for more
information. If you cannot find out the value, you may use the following
reference values: Car batteries (36 - 100 Ah): 500 - 800 CCA, car
batteries (> 100 Ah): 800 - 999 CCA, solar batteries: 300 - 500 CCA.
4. Press the CCA button (6) repeatedly until the value of your battery
is being displayed. An acoustic signal sounds with each press of the
button. The following values, which are in conformity with SAE standard,
are available:
6 V:
12 V:
150, 200, 250, 300, 350, 400, 450, 500
300, 400, 500, 600, 700, 800, 900, 1000
