Operation
Battery Condition
The capacity of the battery is in good condition.
The battery is possibly, but not necessarily, fully
charged. Measuring the specific gravity of the
battery acid will give a precise indication of the
battery condition. If the battery is not fully charged,
it is advisable to check the charging system.
The capacity of the battery is insufficient. The
battery is either defective or partly discharged.
Measuring the specific gravity of the battery acid
will give a precise indication of the battery
condition.
The battery is probably tired or massively
discharged.
Observe the voltage reading on the display directly
after the load test. If the voltage raises quickly to
12 V (6 V) or more, the battery is probably tired. If
the voltage slowly rises, the battery is probably
massively discharged.
Measuring the specific gravity of the battery acid
will give a precise indication of the battery
condition.
