OPERATING THE CHARGER
INDICATOR LEDs
Each bank has the following LEDs:
•
(RED): A solid RED LED indicates there is an issue with the battery connection.
• A fl ashing
RED LED indicates an error. See Troubleshooting on page 15.
• 25%, 50%, 75% (YELLOW): These LEDs indicate the progress of charging.
• 100% (GREEN): Flashing GREEN LED indicates battery is fully charged in Maintenance Mode and ready to use.
• Solid GREEN LED indicates battery is fully charged in long term Maintenance Mode and ready to use.
• Flashing GREEN and 25% YELLOW LEDs indicates the battery is less that 10.5 volts and the charger is in low power safety
mode. Full charging will begin once the battery reaches 10.5 volts. If the battery does not rise above 10.5 volts, then make sure
all loads are disconnected from the battery and try again.
MULTI-STAGE CHARGING
Minn Kota’s Multi-Stage Charging delivers a fast, precise charge profi le by automatically controlling current and voltage without
overcharging your batteries.
Bulk Mode: During this stage, the charger delivers full current until the battery reaches ~75% charge.
Absorption Mode: The charging current tapers down while the battery voltage is held constant (see Table 2 for voltages).
Mild Equalize Mode (Flooded Lead-Acid Only): The voltage is automatically increased with each charging cycle for a
maximum of 1.5 hours to desulfate and mix fl uids in each battery.
Equalize Mode (Flooded Lead-Acid Only): The equalize mode must be manually selected for each bank that is to be
equalized. The voltage is increased for a maximum of 4 hours to desulfate and mix fl uids in each battery.
Maintenance Mode: When the battery reaches full charge, the charger voltage is reduced (see Table 1 on page 14 for
voltages). A fl ashing 100% GREEN LED is lit for each bank to indicate the battery is in Maintenance Mode and ready to use.
After 12 hours, the charger automatically turns off and a steady 100% GREEN LED is lit for each bank to indicate the battery is in
long term Maintenance Mode and ready to use. The charger will automatically resume charging when the battery voltage drops
below 12.6V.
INLINE FUSE
Each output cord has inline fuses on the RED and BLACK leads located near the ring terminals. These fuses serve as protection
from surges and short circuits caused by a damaged charger output cable. If a fuse blows, replace it with a 30 amp ATC 32V
automotive fuse. Improper battery connections will normally not cause a fuse to blow since this is handled by the internal
circuitry of the charger.
