Battery Charger RLD
User's Manual
• STANDARD CHARGERS WITH Wa CHARGE CURVE
The current of charge follows the Wa charge curve, as described in the DIN 41774 Standard.
After some hours, depending by the conditions of the battery, when the battery’s voltage reaches
the value of “gassing” (2,4 Volt per cell), the LED “FINAL CHARGE” starts to flash and the
charge continues.
Wa charge curve.
• FAST CHARGERS WITH WoWa CHARGE CURVE
The current of charge follows the WoWa curve, as described in the DIN 41773 Standard, while
the LED “CHARGE ON” continuously flashes.
The current value, when the charge starts, is 20-40% higher than the standard Wa value, to
reduce the time of charge.
When the "gassing" voltage (2,4 Volt per cell) is reached, the current value is reduced to avoid
overheats in the battery, and the charge continues in the same way of standard Wa models.
WoWa charge curve
When the battery reaches the gassing voltage, the charge continues for one half of the time
needed to reach the gassing voltage, with a minimum total time of 30 minutes.
