SAFETY PRECAUTIONS
PERSONAL PRECAUTIONS
a. Consider having someone close enough nearby to come to your aid when you work near a lead acid battery.
b. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
c. Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery.
d. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flush eye with
running cold water for at least 10 minutes and get medical attention immediately.
e. Never smoke or allow a spark or flame in vicinity of battery, engine, motor or other flammable or explosive equipment.
f. Be extra cautious to reduce risk of dropping a metal tool onto the battery or across the battery terminals. It might spark or
short circuit the battery or other electrical component that may cause an explosion.
g. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead acid battery. A lead
acid battery can produce a short circuit current high enough to weld such items, causing severe burns.
h. Use the Minn Kota battery charger for charging and maintaining FLOODED LEAD-ACID, MAINTENANCE FREE, GEL CELL,
AND AGM / STARVED ELECTROLYTE batteries only. It is not intended to supply power to low voltage electrical systems
other than for charging and maintaining batteries. Do not use the charger for charging dry-cell batteries that are commonly
used with home appliances. These batteries may burst and cause injury to persons and damage to property.
DC CONNECTION PRECAUTIONS
a. The Minn Kota charger will only charge 12 volt 6 cell lead acid batteries including flooded lead/acid, AGM, and GEL batteries.
Do not connect the output of the charger to any other voltage or type of battery.
b. The charger’s DC output terminals are designed to be permanently mounted and connected to batteries.
c. Connect and disconnect DC output terminals only after disconnecting the AC plug from the electric outlet.
d. The charger output leads must be connected with the correct polarity for the charger to function. The RED lead must be
connected to the POSITIVE terminal of the battery and the BLACK lead must be connected to the NEGATIVE terminal of the
battery, as indicated in e(5), e(6) and f(2), f(3).
e. Follow these steps when the battery charger is installed in a boat or vehicle. A spark near the battery may cause battery
explosion. To reduce the risk of a spark near the battery:
1. Position AC and DC cords to reduce risk of damage by hood, door, or moving engine parts.
2. Stay clear of fan blades, belts, pulleys and other parts that can cause injury to persons.
3. Check polarity of battery posts. POSITIVE (POS, P, +) battery post is usually larger in diameter than
NEGATIVE (NEG, N, -) post.
4. Determine which post of the battery is grounded (connected) to the chassis (if any). If negative post is grounded to the
boat hull or chassis (as in most vehicles), see step 5 below. If positive post is grounded to the boat hull or chassis, see
step 6 below. If neither is grounded, the order in which the output leads are connected does not matter.
5. For negative-grounded boat or vehicle, connect POSITIVE (RED) output terminal to POSITIVE (POS, P, +) ungrounded
post of battery first. Then connect NEGATIVE (BLACK) output to NEGATIVE (NEG, N, -) grounded post of battery.
6. For positive-grounded boat or vehicle, connect NEGATIVE (BLACK) output to NEGATIVE (NEG, N, -) ungrounded post
of battery first. Then, connect POSITIVE (RED) output terminal to POSITIVE (POS, P, +) grounded post of battery.
7. When disconnecting charger, disconnect AC power cord from electric outlet first.
8. See operating instructions for length of charge information.

8 | minnkotamotors.com ©2015 Johnson Outdoors Marine Electronics, Inc.
SAFETY PRECAUTIONS
f. Follow these steps when battery is outside boat or vehicle. A spark near battery may cause battery explosion. To reduce the
risk of a spark near battery:
1. Check polarity of battery posts. POSITIVE (POS, P, +) battery post is usually larger in diameter than
NEGATIVE (NEG, N, -) post.
2. Connect POSITIVE (RED) output terminal to POSITIVE (POS, P, +) post of battery.
3. Connect NEGATIVE (BLACK) output terminal to NEGATIVE (NEG, N, -) post of battery.
4. Do not face battery when making final connection.
5. When disconnecting charger, disconnect AC power cord from electric outlet first.
6. When disconnecting output terminals from battery posts, always do so in reverse sequence of the connecting procedure.
7. A marine (boat) battery does not need to be removed and charged on shore. However, instructions must be followed for
location of charger when permanently mounted or used on board.
AC POWER CORD CONNECTION PRECAUTIONS
The Minn Kota battery charger should be grounded to reduce risk of electric shock. The charger is equipped with an electric AC
power cord. The plug must be plugged into an outlet that is properly installed in accordance with all local codes and ordinances.
DANGER: Never alter AC cord or plug provided – if it will not fit outlet, have proper outlet installed by a qualified electrician.
Improper connection can result in a risk of an electric shock.
CAUTION – To reduce risk of fire or electric shock, connect battery charger directly to grounding receptacle (three-prong). An
adapter should not be used with battery charger.
CAUTION - Due to the higher charging current of the Minn Kota charger it is recommended that you check with the battery
manufacturer's maximum recommended charger current before connecting multiple charger outputs to 1 battery.

INSTALLATION
INSTALLATION AND MOUNTING
LOCATING THE CHARGER
a. Never place charger above battery being charged; gases from battery will corrode and damage charger.
b. Never allow battery acid to drip on charger when reading electrolyte specific gravity or filling battery.
c. Do not operate charger in a closed-in area or restrict ventilation in any way.
d. Do not set a battery on top of charger.
e. Do not mount the charger below the waterline of the boat or directly adjacent to fuel tanks.
f. Each DC output cord is six feet long. Make sure that all DC output cords can reach the batteries and that the AC power
cord can reach a power source. When using an extension cord, make the AC connection to the charger outside of the
battery compartment as far away as practical to reduce the risk of a spark igniting gasses in the compartment.
g. Do not shorten the DC output cords, as this can affect charger output..
h. If the DC output cords are not long enough, they may be lengthened by splicing and soldering 12 AWG (minimum) wire. Each
splice should be covered with dual wall adhesive lined heat shrink tubing to protect the joint from corroding. The splice should
be made between the fork in the output cable and the fuse holder. The fuse holder should always remain within 7” of the
battery terminals. The maximum extension length is 15 feet. You may contact the Minn Kota Service Department with any
questions.
WARNING: Do not splice the AC power cord, as this voids the three year Limited Warranty.
i. Even though the Minn Kota charger is capable of operating in a high ambient temperature environment, a minimum of six
inches of unobstructed area should be allowed on all sides of the unit for proper air circulation and cooling. Proper cooling and
circulation will allow the charger to operate at peak efficiency.
MOUNTING THE CHARGER
Due to the weight of the charger and the impact that boats routinely endure, take the time to securely mount the charger to
prevent damage. Mounting with nuts, bolts and washers is preferable to mounting with screws.
1. Use the largest diameter bolts possible and use all four mounting holes.
2. After marking the locations, set the charger aside and drill the holes.
3. Apply a marine grade silicone sealant in each of the drilled holes to create a waterproof seal.
4. Then secure the charger in place using the mounting hardware.
NOTE: Your battery charger is supplied with an AC plug holder designed to hold the power cord plug when not in use. Mount
the AC plug holder with four screws in a convenient dry site to prevent corrosion to the AC plug and to prevent the AC plug from
making contact with the battery posts.
WARNING: Make sure the charger is disconnected from ac power before connecting the batteries to the output cords.
CAUTION: Before making any connections to batteries in a confined space (such as a battery compartment of a boat), open
the door or hatch of the compartment and allow it to air out for 15 minutes. This allows any gasses that have accumulated in the
compartment to escape.

SELECTING THE BATTERY TYPE
The charger can be manually switched between 4 different modes; Gel Cell, Flooded Lead-Acid, AGM/High Performance AGM,
and Equalize. In order to optimize the performance of your batteries or to prevent damage, you will need to properly set each
charger bank for the correct battery type (each bank can be independently set). The factory default setting is Flooded Lead-Acid.
To set the battery type:
1. Plug the charger AC cord into an AC outlet.
2. During power up all LEDs will turn on, then 1 YELLOW LED will temporarily remain on. This YELLOW LED will indicate the
current battery type.
3. To change battery type press and hold the Battery Selection button until the YELLOW LED indicates the desired battery
type, then release the button. The battery type will be saved even if the AC cord or DC output cords are disconnected.
Flooded Lead-Acid batteries should be equalized per the battery manufacturers’ recommendations. Only Flooded Lead-Acid
batteries should be equalized. The charger will only allow selection of the Equalize Mode if the previous selection was Flooded
Lead-Acid. To set Equalize Mode, press and hold the Battery Selection button until all 3 YELLOW LEDs are lit, then release the
button. Once in Equalize Mode, the equalize process will only be performed one time. Once this cycle is completed or if the cycle
is interrupted (by unplugging the AC or a DC cord) the charger will revert back to the Flooded Lead-Acid battery type
WARNING: Battery type is factory preset for Flooded Lead-Acid. If you are using alternate type batteries, select Gel or
AGM/High Performance AGM. Failure to do so could result in damage to your battery and/or cause acid leaks.
GENERAL OPERATION
After the AC cord on the charger is plugged in and a battery is connected to the output cable correctly, the 25% charging LED will
turn on. After 4 seconds the charger will begin charging the battery. The 4 second delay is added to allow the user to establish a
good connection before the charger output is turned on. This will help prevent unwanted sparks during battery connections. The
YELLOW LEDs will indicate how far the charger is in the charging process. Once the 100% GREEN LED is flashing, the charger
is holding the battery in Maintenance Mode. The charger will stay in Maintenance Mode for 12 hours. After 12 hours in the
Maintenance Mode, the charger output will turn off and the 100% GREEN LED will switch to steady GREEN.
NOTE: If a RED LED is flashing, reference the troubleshooting section on page 15 to determine
the reason and take the necessary corrective action to remedy the situation. If you are unable to
remedy the situation and need help, call the Minn Kota Service Department at 1.800.227.6433 and a
technical support representative will be happy to assist you.
CAUTION: We recommend that you not recharge your battery, (or batteries), with the watercraft
or motor lower unit in the water during electrical storms. Severe damage to the motor or charging
system may occur if lightning strikes nearby or if storm related high voltage conditions exist.
CAUTION: If using a generator to power the charger, it must have a clean output and be safe for use
on electrical equipment. Generators with a sine wave output can be used to power this charger. See
Table 1 for power requirements.
WARNING: To reduce risk of electric shock, do not perform any servicing other than those contained in the operating
instructions.

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 flashing 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 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.
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 fluids 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 fluids 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 flashing 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.

FREQUENTLY ASKED QUESTIONS
Q Are Minn Kota On-Board Precision Chargers tested and approved for use with Odyssey batteries?
AAll Minn Kota On-board Precision Chargers have been tested by Odyssey and found to properly charge all batteries rated
from 7-114 Ah.
Q Are the Minn Kota battery chargers waterproof?
AYes, the battery chargers are waterproof, however, they should not be operated while immersed.
Q Can I charge two batteries on one charger bank?
AYes, but it is not recommended. It takes double the amount of time to charge two batteries and could result in an error being
displayed if the batteries take too long to charge.
Q Can I connect two charger banks to one battery?
AYes, this will charge the battery almost twice as fast. However, the water in the battery is more likely to evaporate with higher
charging currents. Thus, the electrolyte level should be checked more often. The maximum safe charging current on most
deep cycle batteries is 20 amps. Consult your battery manufacturer for recommendations.
Q Can I extend the Minn Kota battery charger output leads?
AYes, please refer to Accessory Kit 1820089 - MK-EC-15 Wire Extension Kit (see Pg. 10).
Q Can the Minn Kota battery charger be mounted in any position?
AYes, but it is highly recommended that the charger not be mounted below the waterline.
Q Do I need to disconnect the series or parallel battery connection(s) when using Minn Kota chargers?
ANo, the battery jumper wire(s) can remain in place for both types of wiring.
Q Does losing AC power or unplugging the Precision charger from an AC outlet affect battery type selection?
ANo, once a battery type is selected it will be stored until a new battery type is selected by the user.
Q Does losing AC power or unplugging the Precision charger from an AC outlet affect Deep Equalization
mode?
AYes, the Deep Equalization mode is cancelled and the charger will restart the charging cycle in normal Flooded Lead Acid
battery mode.
Q How do I set Equalization mode on my Minn Kota Precision charger?
AMinn Kota Precision Chargers feature Automatic Equalization Technology that cleans and conditions batteries with each
charge cycle (flooded Lead-Acid only). Precision Chargers also feature a user selectable by bank Deep Equalization Mode.
Select Deep Equalization Mode (recommended every 30th charge cycle) – Deep Equalization should only be performed
on Flooded Lead-Acid batteries. Before you can select Deep Equalization mode you must first make sure that the current
battery selection is set to Flooded Lead Acid. Press and hold the “BATTERY SELECTION” button until you see three yellow
LED’s illuminate, then release the “BATTERY SELECTION” button. If any of the yellow LED’s begin to flash you are in Deep
Equalization Mode.
NOTE: The state of charge LED’s will continue to flash through the entire charge cycle including the 12-hour maintenance
mode.
Q How often should I perform Deep Equalization?
ADeep Equalization is recommended every 30th charge cycle or once a year.
Q How do I determine what battery type is selected on my Minn Kota PC Charger?
APress and release the “BATTERY SELECTION” button. The yellow LED located next to the corresponding battery type
selected will illuminate for 2-5 seconds.
Q How warm do Minn Kota battery chargers get?
AThe Minn Kota battery chargers can reach 150° F. They may get warm in an enclosed area. The maximum recommended
room temperature for charging batteries is 122° F. If the charger seems to get “hot,” try opening a hatch to help cool the
charger. When the charger is hot, the output current will drop to protect the charger and the battery.
Q What happens if AC power is lost during a charging cycle with the Minn Kota Precision battery charger?
AThe PC charger will simply restart the charging cycle with the battery type that was originally selected. Losing power or
unplugging the PC charger does not clear your battery type selection.
Q What size fuses are used on Minn Kota battery chargers?
AChargers with a yellow fuse holder use a 30 amp AGX 32V automotive fuse. An AGC can be used but may not fit as well as
the AGX. Chargers with a red fuse holder use a 30 amp ATC 32V automotive fuse.

FREQUENTLY ASKED QUESTIONS
Q What Batteries can be charged by a Minn Kota charger?
AMinn Kota Chargers can charge 12 volt 6 cell lead-acid batteries. Minn Kota D Series Chargers and Minn Kota Portable
Chargers work well with Flooded Lead Acid and AGM battery types. Minn Kota PC series Chargers have optimized charging
for Flooded Lead Acid, AGM and Gel battery types. You should verify with your Battery’s Manufacturer the maximum Amp
input for your Battery. The Amp Hour or AH rating for your battery should be in the range indicated below for the per bank
amp output of the battery charger selected.
BATTERY CHARGER
OUTPUT PER BANK
BATTERY AMP
HOUR RATING
5 AMPS 20-125 AH
6 AMPS 24-125 AH
10 AMPS 40-125 AH
15 AMPS 60-180 AH
Q Why do the LED’s on my Precision Charger stay illuminated for a period of time after unplugged from AC
power?
AThis is normal and does not affect your batteries. It is simply a function of the Precision charging ensuring the charger is
disconnected prior to terminating the charge cycle.
The PC charger takes many complex and detailed measurements of the battery during a charge cycle. The software in the
charger processes this information to make the best possible decisions to give your battery the best charge on the market.
In some cases the measurements and software algorithms make it difficult to detect when AC has been disconnected and
therefore the charger may take a while to power down and turn off.
Q Will I damage my batteries if I leave the charger plugged in over long periods of non-use (like storage)?
ANo. Minn Kota’s on-board chargers float the battery voltage between 13.2V and 13.5V in the “maintenance” stage (3rd
stage). This will allow you to keep your battery charger plugged in for long periods of time without “boiling the battery dry.”
Note: It is important to check the electrolyte level approximately every 30 days. Batteries should be filled after charging,
and the electrolyte level should be even in all cells and below the fill well in each cell. If the battery plates are exposed before
charging, add just enough water to cover the plates. If the battery is overfilled before charging, it may overflow during
charging.
Q Can I charge Lithium batteries?
AMinn Kota has not worked directly with any Lithium battery suppliers to determine if our charger are compatible with their
batteries. Most of the Lithium Battery manufactures post required charge stage information on their web sites.
Q Are any of the charger foot prints compatible with other chargers?
AFootprints are not compatible with different charger models and sizes. The only exception is the MK212PC, MK318PC,
MK220PC and MK330PC have compatible footprints.
Q Are the chargers serviceable?
AThere are no serviceable components inside the charger.
Q Can one bank be disconnected while charging batteries on other banks?
AYes, The charger banks are fully independent chargers. Unused banks can be left disconnected from batteries. The output
of the unused banks are not energized. It is always a good idea to cover or tape the loose end to prevent shorting of other
electrical systems in the boat.
Q Can I use a portable generator to run my charger?
ACareful selection should be used when deciding on a portable generator for electronics. There are 2 important factors that
must be considered:
- Output power: Generators are marketed in output wattage. This wattage must be higher than the power required by
the battery charger. Please review power requirements stated in the user manual for your specific charger.
- Output type: MinnKota chargers require clean output power from the generator to prevent permanent damage. The
generator must replicate the power from a standard AC outlet in your home (sine wave output).

GENERAL MAINTENANCE
• Check battery charger for dirt, oil, battery corrosion, etc. Use a water and baking soda solution for cleaning corrosion. Wipe
clean using a dry cloth.
• Check ring terminals for dirt, oil, and battery corrosion; then disconnect from battery posts and clean as necessary with water
and baking soda solution and dry with a clean cloth.
• When the charger is not in use, coil the power cord to prevent damage.
• When storing the battery charger, store in a clean dry area.
• If power cord or plug becomes damaged, you may contact the Minn Kota Service Repair Department for service repair
information. Otherwise, dispose of the battery charger in compliance with local law. Damaged cords and plugs can cause
