Equalization: Equalization charging raises the battery voltage to higher
than the standard supplementary voltage to charge the battery. Certain
types of lead-acid batteries benefit from regular equalization charging, which
can agitate the electrolyte, balance the battery voltage, complete a chemical
reaction, and prevent battery vulcanization.
Note: Only FLD, SLD and AGM can perform equalization charging. The
equalization charge will be carried out every 30 days, and the charge time
is 120 minutes. When the battery is charged in equalization, the boost
charge stage will not be performed.

BATTERY VOLTAGE
CHARGING CURRENT
①Bulk Charge: Constant current charging, providing the maximum current
to the battery until the battery reaches the boost charge voltage.
②Boost Charge: Charge with a constant voltage. When it is about to be fully
charged, the charging current starts to drop, and finally charges with a small
current. During this process, the charging voltage is constant to maintain the
boost charge voltage.
