4.3 CHECKING USING A BATTERY TESTER
-
The general condition of the battery can be
checked quickly using a battery tester. For
this check, a load is applied to the battery,
and then the discharge voltage at the
battery terminals is measured. The load
applied to the battery must be at least 3
times the capacity of the battery.
-
As a rule, the test can be carried out when
the battery is sufficiently charged (relative
density 1.25 - 1.28 kg/dm
3
).
At normal temperatures (10-20
_C), the
charging voltage for a properly charged
battery must be 10 volts after 10 seconds.
In the case of a partially discharged battery
(relative density 1.25 kg/dm
3
), the reading
should be at least 9 volts.
It is important that the voltage is measured
directly at the battery poles.
