2.6 Battery Charger

The generator set is equipped with a 6-amp float/equalize battery charger to maintain the engine starting battery. The charger’s power cord must be connected to a 120 VAC power source. Figure 2-5 illustrates the battery charger.

The battery charger uses an AGS 10 inline fuse. The fuse is located in the battery lead. See Figure 2-5.

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 4.5 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 4.5 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 4.5 in this manual.
