Figure 2-5 illustrates the three-stage charging method.
Red and green LEDs indicate charger operation. The
chart in Figure 2-6 describes the LED indicator
operation during each stage of the charging process.
Figure 2-5 Charging Method
Display Operating Condition
Red ON When the red LED is on, it indicates the battery is discharged and the battery charger is recharging at the BULK rate
Green OFF (stage 1). This charging rate is 6 amps. While the red LED is on, the voltage measured (with the battery charger on) will be
11.8--14 volts.
If the red LED stays on for more than 24 hours, refer to Section 4.4 in this manual.
Red ON When both the green and the red LEDs are on, the battery charger is charging at an ABSORPTION rate of between 1.5 and
Green ON 5 amps (stage 2). This mode of charging gradually tops off your battery, and reduces harmful sulfating. While both LEDs
are on, the voltage measured (with the battery charger on) should be approximately 14.0--14.5 VDC.
If both LEDs stay on longer than 24 hours, refer to Section 4.4 in this manual.
Red OFF When the green LED is on, the battery charger is charging at a FLOAT or MAINTENANCE rate of less than 1.5 amps
Green ON (stage 3). Your battery is now 90% charged and ready for use. This float charging current will gradually decrease to as low
as 0.1 amps as the battery reaches 100% charge. It will now be kept at full charge without overcharging.
If the green LED stays on when your battery is known to be low, refer to Section 4.4 in this manual.
