1) IMPORTANT SAFETY INSTRUCTIONS
a) SAVE THESE INSTRUCTIONS! This manual contains important safety and operating instructions applicable to the safe and efficient use of your
Minn Kota battery charger.
b) The Minn Kota battery charger is a powerful electrical device. If incorrectly installed, configured or operated, the battery charger can damage
batteries and / or electrical equipment. Please read thoroughly the instructions and safety information contained in this manual before operating the
battery charger.
c) Use of an attachment not recommended or sold by Johnson Outdoors Inc. may result in risk of fire, electric shock, or injury to persons or property.
d) The charger is not intended for use by young children or infirm persons without supervision. Young children should be supervised to ensure that they do not
play with the charger.
e) To reduce risk of damage to electric plug or cord, pull by the plug rather than the cord when disconnecting the battery charger.
f) An extension cord should not be used unless absolutely necessary. Use of the improper extension cord could result in a risk of fire or electric
shock. If extension cord must be used, make sure:
i) That pins of plug of the extension cord are the same number, size and shape of those of the plug on the battery charger;
ii) That extension cord is properly wired and in good electrical condition;
iii) That wire in extension cord is proper size as follows:
Minimum recommended AWG wire size for various length extension cords used with the Minn Kota
battery charger:
Length of Cord in Feet 25 50 100
AWG Size 16 14 12
g) Do not operate the battery charger with a damaged cord or plug.
h) Do not operate the battery charger if it has received a sharp blow, been dropped or otherwise damaged in any way.
i) Do not disassemble the charger. Incorrect reassembly may result in a risk of electric shock or fire.
j) To reduce risk of electric shock, unplug the charger from outlet before attempting any maintenance or cleaning. Disconnecting the leads will not
reduce this risk.
k) To reduce risk of shock or spark, never touch the battery clips together while the charger is plugged into an outlet or extension cord.
l) External connections to the battery charger shall comply with all local, state, and federal regulations.
WARNING: RISK OF EXPLOSIVE GASES
WORKING IN THE VICINITY OF A LEAD ACID BATTERY IS DANGEROUS. BATTERIES CONTAIN SULFURIC ACID AND PRODUCE
EXPLOSIVE GASES. A BATTERY EXPLOSION COULD RESULT IN LOSS OF EYESIGHT OR SERIOUS BURNS. FOR THIS REASON, IT IS
OF UTMOST IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
TO REDUCE THE RISK OF BATTERY EXPLOSION, FOLLOW THESE INSTRUCTIONS AND THOSE PUBLISHED BY THE BATTERY
MANUFACTURER FOR ANY EQUIPMENT YOU INTEND TO USE IN THE VICINITY OF THE BATTERY. REVIEW CAUTIONARY MARKINGS
ON THESE PRODUCTS AND ON ENGINE, MOTOR OR OTHER EQUIPMENT REQUIRING BATTERY USAGE.
WARNING – DO NOT ATTEMPT TO REPAIR OR SERVICE THE CHARGER YOURSELF. OPENING THE CHARGER MAY EXPOSE YOU
TO HIGH VOLTAGES, THE RISK OF ELECTRIC SHOCK, AND OTHER HAZARDS.
2) 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 flood 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 battery. It might spark or short circuit battery or other electrical part that may
cause 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 / WET CELL, MAINTENANCE FREE, 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.
i) NEVER charge a frozen battery.
3) PREPARING TO CHARGE
a) If necessary to remove battery from boat or vehicle to charge or maintain, always remove grounded terminal from battery first (if applicable).
Make sure all accessories in the boat or vehicle are off, so as not to cause an arc.
b) Be sure area around battery is well ventilated while battery is being charged or maintained.
c) Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d) Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. Do not overfill. For a battery without remov able cell caps, such as valve regulated lead acid batteries, carefully follow manufacturer’s recharging instructions.
e) Study all battery manufacturers’ specific precautions and recommended rates of charge while charging.
4) DC AND AC CONNECTION PRECAUTIONS
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.
a) The Minn Kota charger will only charge 12 volt 6 cell lead acid batteries. Do not connect the output of the charger to any other voltage or
type of battery.
b) The charger’s DC output leads are designed to be temporarly connected to the battery.
c) Connect and disconnect DC output leads only after removing 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.
5) CHOOSING THE CHARGING LOCATION
a) The input (AC) power cord is 6 feet long and the output (DC) battery leads are also 6 feet long. Make sure that all the DC battery leads can reach
the batteries and that the AC power cord can reach the power source. Do not splice any battery lead or power cord, as this voids the three year
Limited Warranty.
b) Even though the Minn Kota charger is capable of operating in a high ambient temperature environment, a minimum of 6 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.
CONNECTING THE BATTERIES TO THE CHARGER:
WARNING – MAKE SURE THE CHARGER IS DISCONNECTED FROM AC POWER AND THE ON/OFF SWITCH IS IN THE OFF POSITION
BEFORE CONNECTING THE BATTERY TO THE OUTPUT LEADS.
CAUTION - Before making any connections to batteries in a confined space, 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.
