6.Explanation of operation logic (charging stages):
PB-600 has a total of 3 charg in g modes to choose from, 2 sta ges, 3 stages, and
8 stages. 8 stages charging differ from 2 stages with the addition of pulse, soft start,
analysis, recondition, float, and maintain stages. 2 stages provide simple and quick
charging. 3 stages is similar to 2 stages with the exception of not shutting OFF after
the battery is fully charged. Lastly, 8 stages will allow charging to maximum capacity.
User can select between 2,3 or 8 stages depending on their requirement.
6.1 2 stage charging (flick switch to "2" stage)
During initial charge (stage 1), charger will provide maximum current to the battery.
The built-in fan will also turn ON. As the battery starts to get full, charging current
will gradually decrease (stage 2). When charging current decrease to less than
10% of max. LED indicator will turn Green to show a full charge and the charger
will turn OFF.
