The Universal Loading Charger LOG series chargers have the ability to charge all types
of batteries commonly present on the market, depending on their construction technology
and user needs.
Each Universal Loading Charger LOG charger model can be customized by setting
the charging curve according to user needs, modifying three parameters:
nominal battery voltage, charging current and battery type.
It is possible using the five touch buttons on the display.
To see the actual settings of a battery charger, consult :
„Operation - commands and displays" section.
Depending on the type of battery set, the charge curve will reach different end of charge
voltage. Refer to the following list to make sure the charger is set correctly for the battery
you are charging:
WET: Free lead acid
End of charge voltage: 2.4V / element
WET DEEP: Free lead acid with deep charge
End of charge: 2.65V / element
GEL: Lead-acid with electrolyte in gel form
End of charge voltage: 2.35V / element
AGM1: Lead-acid with electrolyte absorbed by glass microfiber
End of charge voltage: 2.38V / element
AGM2: Lead- acid with electrolyte absorbed by glass microfiber
End of charge voltage: 2.45V / element
The charging process is divided into 5 phases, see fig.B pag. 2:
1 - Analysis. When the battery is connected, the charger performs an analysis.
2 - Bulk. Constant current initial charge phase.
3 - Absorption + Final. Constant voltage charging phase in which the current
absorbed by the battery drops.
4 - Conditioning + Final. Optional deep charge stage. (WET DEEP only)
5 - Floating: Final charge phase in buffer, the charger acts as a charge
maintainer for the entire time it is connected to the battery, bringing the
voltage to 2.25V / element to avoid self-discharge over time.
U.L.C. LOG series battery chargers are equipped with a desulphation mode «Desulf».
The desulphation occur with a supply of costant current for a programmable time
from 2h to 100h during which it's applied an higher voltage compated to a normal charge.
