Test outcome
Once the test is complete, the display will
show:
the health condition in (%), the CCA in (A),
the charge status in (%), the voltage (V),
the internal resistance in (mOhm), the rated
current value (data plate) of the battery.
The display also shows:
- GOOD BATTERY:
The battery is good and capable of
maintaining charge.
- GOOD - CHARGE:
The battery is good, but must be charged
ATTENTION: The battery can be restored,
but over time the engine cranking capacity
will be reduced. The battery may not work
in extreme weather conditions. There
may be a connection problem between
the vehicle and the battery that inhibits
the charge function. Pay attention and
consider replacing the battery and check
the charge system.
- RETEST CHARGE:
