Battery Charger Operation
Red and green LEDs on the charger indicate the charge
rate. Refer to Figure 6-24 for a description of the LED
indicator operation. Figure 6-25 and Figure 6-26 show
the 3-stage charging charging method for 12 VDC and
24 VDC configurations.

The battery is discharged and the charger is recharging at the BULK rate (stage 1). This charging
rate is 6 Amps at 12V or 3 Amps at 24V. The measured voltage (with the charger on) is 11.8 to 14
Volts in 12VDC mode or 23.6 to 28VDC 24VDC mode.
If the red LED stays on for more than 24 hours, refer to Problem 1 in the troubleshooting section in
this manual.

The charger is charging at an ABSORPTION rate of between 1.5 and 5 Amps (stage 2). This
mode of charging gradually “tops off” your battery, and reduces harmful sulfating. While both LED’s
are on, the voltage measured (with the charger on) should be approx. 14.0 to 14.5VDC in 12VDC
mode or 28.0 to 29.0 in 24VDC mode.
If both LED’s stay on longer than 24 hours, refer to Problem 2 in the troubleshooting section in this
manual.
Off
On
The charer is charging at a FLOAT or MAINTENANCE rate of less than 1.5 Amps, (stage 3). The
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. The float rate maintains the battery at
full charge without overcharging.
If the green LED stays on when your battery is known to be low, refer to Problem 3 in the
troubleshooting section in this manual.
