STAGE 4: EQUALIZE
Certain battery types benefit from regular equalizing charge, which can stir electrolytes, balance battery voltage, and
complete the chemical reaction. The equalize charge increases the battery voltage above a standard voltage, causing
vaporization of battery electrolyte. By default, this happens every 30 days for flooded batteries.
RECHARGE
After the battery is completely charged the charging cycle completes and the battery is allowed to slowly discharge until it
reaches the charge return voltage at which point a new charge cycle is initiated.

Warning: Risk of explosion!
Equalizing vented lead-acid battery may generate explosive gases. So, the battery
compartment must be well ventilated.
Caution: Damage of device!
Equalization can increase the battery voltage to levels that may damage sensitive DC loads.
It is necessary to verify that the allowable input voltage of all system loads is greater than the
equalizing charge set value.
Caution: Damage of device!
Over charge and excessive gas evolution may damage the battery plates and cause active
substances on the battery plate to come off. Equalizing charge may cause damage if voltage
is too high or time is too long. Please carefully check the specific requirements of battery
used in the system.
