Charger Status Lights:
Each post comes equipped with a dual battery charger which provides charging for two 12 VDC
batteries (in series makes 24 VDC). Each charger is rated for 120 VAC, 60 Hz, 4 Amp draw. Keep
this in mind if using extension cords and multiple adapters into a single outlet. (4 chargers will draw
4 x 4 amps = 16 amps total). There are three charging levels that the charger progresses through to
full charge. Refer to the MINN KOTA MK220D manual enclosed at end of this manual. Bank 1
Refers to battery on the left (as viewed from the control box), Bank 2 is battery on the right (under
the charger).
Note that to protect the charger, the lift will not function when power is supplied to the charger
receptacle. Once power is supplied to charger receptacle, “Power On” light illuminates on charger
and lift control panel will power.
Bulk Charging Mode: Each bank will show Solid Yellow Lights. (charger delivers full current to
batteries until they reach ~75% charge)
Absorption Charging Mode: Each bank will show Flashing Yellow Lights. (charging current
tapers down while battery voltages held at 14.4V at 77DegF.)
Maintenance / Float Charging Mode: Each bank will show Flashing Green Lights. (charger
voltage dropped to 13.4V per bank to maintain full charge on battery)
Ready: Each bank will show
Solid Green Lights. (batteries have been in maintenance mode for
more than 24 hrs).
Any
Red Light would indicate error in charging. Consult charger section for details.
NOTE: Avoid halting charging cycle until batteries are fully charged (this may decrease the life and
charge holding capacity of the batteries). Do not recharge fully charged batteries. Status of left
battery may differ from status of right battery. Wait until both batteries are fully charged prior to
using lift.
