TBB Trident Manual page 10

Equalization is used for FREEDOM batteries ONLY, it can ensure that the
individual cells within the batteries are fully charged, equal to one another, and that
the electrolyte is stirred up by the gassing of the cells. But this function was strongly
recommended not to use over once a month.
Please do read the related information about equalization charging in 4.2 before
you do it to battery.
WARNING
Please ensure you set the dip switch 2 and 3 back to OFF when you
finished the equalization charging each time.
Only be active after the battery charger is power ON.
As a protection, TRIDENT will stop charging if the switch is set to ON
before the battery is power on.
