Explanation for 3 stages charging curve
(0)Initial stage (battery analysis):
(1)Stage 1 (constant current):
(2)Stage 2 (constant voltage):
(3)Stage 3 (Float voltage):
*For applications that utilize the charger (PB-600) to charge batteries and supply
system power simultaneously(e.g. UPS system), please select "3 stage" charging
for the best use of the charger.
Check battery voltage level to see if it is within the normal range, whether or not
a battery is connected, or if the battery is already full and further charging is not
required.
A constant current is provided so the battery can be quickly charged to 2.4V per cell.
A constant voltage of 2.4V per cell is provided until the charging current naturally
A float voltage of 2.3V per cell is provided so that the battery can maintain full charge.
tapers down to 10% then move on to stage 3.
6.3 8 stage charging (flick switch to "8" stage)
8 stage charging provides optimized charge to lead acid battery. It also prolongs
battery life and increase storage capacity. Some of the main advantages are as
below:
Advantage of pulse stage: Use pulse current to revive aged battery.◎
Advantage of recondition stage: Allow full charge of battery.◎
Advantage of float and maintain stage: After LED turns green, maintenance ◎
charge is provided so the battery is always in a full state. User will have access
to a full battery whenever it is disconnected from the charger.
