Attention!
La mode d'égalisation devrait être faite sur des batteries ventillées, inondées (batteries non-scellées ou «mouillées»)
et pas sur des batteries scellées (AGM) ou cellulles gelées et, aussi souvent que les recommandations du fabricant.
4 Stage battery Charging Cycle is used in the Equalization Mode. Equalization Mode is selected
using optional remote Control EVO-rC (see Appendix A). Equalization of the batteries is carried
out periodically - normally once per month for battery under heavy duty service and every two
to four months for battery under light duty service. As equalization is a deliberate overcharge of
the battery for a specified time period, equalizing your flooded / wet cell batteries will reduce
sulfation, stir up the electrolyte to remove stratification, equalize voltages of individual cells and
thus, help reach and maintain the peak capacity of the battery.
The 4 stages of the cycle will be - bulk, Absorption, Equalization, and float. Equalization Mode is
desirable for the proper health of Wet Cell batteries. Equalization voltage is programmable
through the optional remote Control Model EVO-rC (see Appendix A). Programmable voltage
range and default values are shown in Table 6.2.
Equalization current and Equalization time are computed automatically. (See Section 5.8)
fig 5.2 shows the voltage and current curves during the 4 stages of charging in this mode.
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
(Constant 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.

Note 1: The voltage curve
shows the voltage output of
charger. The intrinsic battery
voltage may be di erent and
will be proportional to the
state of charge.
Note 2: The graph is for 12V
version. For 24V version,
double the voltages.
