When Equalization is selected (requires optional Remote Control Model EVO-RC (see Appendix
A), the charger will first execute Bulk Stage followed by Absorption Stage. On completion of
Absorption Stage, the charger will execute Equalization Stage. After completion of Equalization
Stage, the charger will enter Float Stage. The stage transitions will thus be: Bulk Stage (Con-
stant Current)
Absorption stage (Constant Voltage)
Equalization Stage (Constant Voltage)
Float Stage (Constant Voltage).
As part of the
Adaptive Charging Algorithm
, the charging profile in the Equalization Stage
is based on the time
To
which is the time the charger remains in the initial Bulk Stage. The
charger will remain in the initial Bulk Stage for a longer duration when the battery is deeply
discharged and for a shorter duration if the battery has a shallow discharge.

!
CAUTION!
For effective equalization to take place, it is desirable that the batteries undergo a
longer Bulk Stage applicable to the deeply discharged condition of the battery.
•
Please ensure that before the batteries are equalized, they should be deeply
discharged to 20% of its capacity. The Standing Voltage (Terminal Voltage after
disconnecting charging source[s] and load[s] for at least 3 hours) at 20% capacity
will be:
o
12V Battery: Around 11.7V
o
24V Battery: Around 23.4V
•
Do not equalize partially or fully charged batteries
!
ATTENTION!
Pour une
égalisation
efficace, il faut que les batteries subissent à une
étape
majeure plus long en fonction de
la condition déchargée de la batterie.
•
Veuillez assurer que les batteries sont profondément déchargées (à 20% de sa capacité), avant de les
égaliser. La tension constante (la tension de la borne après avoir déconnecter toutes sources de charge
pour un minimum de 3 heures) quand elles sont déchargées à à 20% de sa capacité, serait:
o
Une batterie de 12V: Environ 11,7V
o
Une batterie de 24V: Environ 23,4V
•
N’égalisez pas des batteries qui sont partiellement ou complètement chargées
