5.6.3 Float Stage
Float Stage is a maintenance stage in which the output voltage is reduced to a lower level, typi-
cally about 13.5 volts, (27 volts for 24V models) to maintain the battery’s charge without losing
electrolyte through gassing and also prevent corrosion of Positive plate by maintaining proper
Positive plate Polarization Voltage. Programmable range value of Float Voltage are shown in
Table 6.2.
This stage is displayed as "Float" in the Charging Mode screens in the Remote Control
EVO-RC (Appendix A).
5.6.4 Automatic Resetting of Charging Cycle in 3 Stage Charging Profile
The charging cycle will be reset as follows:
- If the AC input from the Grid/Generator is disconnected and is reconnected or the battery
voltage drops below 12 VDC / 24 VDC.
- If the charger remains in the Float Mode for 10 days.
5.7 4 STAGE CHARGING IN EQUALIZATION MODE
!
CAUTION!
Equalization Mode should be performed only on vented, flooded (non-sealed or
“wet”) batteries and not on the sealed AGM / Gel Cell batteries and only as often as
recommended by the battery manufacturer.
!
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 car-
ried 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 over-
charge 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.
Please read about the necessity and details of equalizing batteries under White Paper
titled “Batteries, Chargers and Alternators,” available online at www.samlexamerica.
com (Home > Support > White Papers).
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.
