MULTI-STAGE CHARGING
Minn Kota's Multi-Stage Charging delivers a fast, precise charge profile 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. When charging Lithium batteries, the charger will
stay in Bulk Mode until the process is complete.
Absorption Mode
The charging current tapers down while the battery voltage is held constant. See the "Charging Profile" information for more details.
Mild Equalize Mode
Mild Equalize Mode is for Flooded Lead-Acid batteries only. The voltage is automatically increased with each charging cycle for a maximum
of 1.5 hours to desulfate and mix fluids in each battery.
Equalize Mode
Equalize Mode is for Flooded Lead-Acid batteries 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 fluids in each battery.
Float Mode
When the battery reaches full charge, the charger voltage is reduced. See the "Charging Profile" table in the General Operation section of
this Manual for voltages. A flashing 100% GREEN LED is lit for each bank to indicate the battery is in Float Mode and ready to use. After
24 hours, the charger outputs automatically turns off and a steady 100% GREEN LED is lit for each bank to indicate the battery is ready
to use. The charger will automatically resume charging when the battery voltage drops below 12.6V.
LED PATTERNS
Each bank has the following LEDs:
Lead Batteries (Flooded / AGM HP AGM):
•
25%, 50%, 75% (YELLOW) - These LEDs indicate the
progress of charging.
•
100% (GREEN): Blinking GREEN LED indicates battery is
fully charged in Float Mode and ready to use. Solid GREEN
LED indicates battery is fully charged in long term Float Mode
and ready to use.
(RED) - A solid
RED LED indicates there is an issue with
•
a connection. A blinking
ERROR CONDITIONS in the "Troubleshooting" section of this manual.
Lithium Batteries:
•
The 100% GREEN LED will blink indicating the charging process is under way and will continue until the charging process
is complete.
•
When the 100% GREEN LED is solid the charging process has completed and the battery is ready to go.
