Charge Algorithms

Table C-1 summarizes the voltage and current setpoints for the charging algorithms. These voltage setpoints are applied for a battery temperature of 20°C. To determine the voltage setpoints at other temperatures, apply the temperature coefficient as follows:

			V			=	V			TC ⋅ (TX – 20°)
				TX				20°		+ -----------------------------------------
										1000
		For example, generic gel float voltage at 50° will be
										mV		° – 20°)
										–27-------- ⋅ (50
			V			=				°C
					50°		13.8V + -----------------------------------------------------= 13.0V
										1000

	* The charger	delivers maximum	available current						to power the DC		loads: it is not		limited by battery		size.
	** See “Max Current (%C)” in your manual.
