c)
A battery voltage dependent on the battery’s state of charge is now shown on the display instru-
ment of the device. If the displayed voltage is less than 12.4
V (6.2
V), the battery should be
charged by a load test. If the voltage is still below 12.4
V (6.2
V) after charging, it can be as-
sumed that the battery is defective.
d)
If the needle of the display is at the extreme left end of the display, the battery tester is
connected with the wrong polarity.
2. Determine the correct measuring range on the scale.
a)
Determine the capacity or cold test current of the battery under test. The cold test current is also
printed on the battery as “CCA” (Cold Cranking Amps) in Ampere (A).
b)
On the scale, you will find a green area below 12
V, graduated from 200–1000
CCA. To evaluate
the test result, select the scale corresponding to the battery.
c)
If no cold test current is printed on the battery, use the table below to select the appropriate
scale:
Battery capacity
(Ah)
Cold test current CCA
(A)
36–44
200
55–66
400
75–88
600
95–110
800
180
1000
3. Press the test switch for 10
s.
Observe the indicator needle of the instrument carefully. Remember where the needle is at the end of
the 10
s. Assess the battery according to the following battery load analysis.
Battery load analysis
Loading test
Battery condition
Ok (green field)
The battery is in good condition and can be fully
charged if necessary.
Weak (yellow field) = Needle rests constantly.
Battery performance is not satisfying. The battery
is either defective or partially discharged. Deter-
mine the battery charge level with a hygrometer
(measure acid density)
Bad (red field) = Needle drops constantly.
The battery is faulty (e.g., due to a bad cell). As a
counter-check, release the switch and observe the
reaction of the voltmeter. If the display returns to
12
V within a few seconds, the battery is defective.
If, on the other hand, the battery voltage rises
slowly, the battery is probably only very severely
discharged.
