Selecting The Correct Batteries; Using Dc Or Alternator Chargers; Additional Accessories Connected To Trolling Motor Batteries - MINN KOTA ULTREX Installation Instructions Manual

SELECTING THE CORRECT BATTERIES

The motor will operate with any lead acid, deep cycle marine 12 volt battery/batteries. For best results, use a deep cycle, marine
battery with at least a 105 amp-hour rating. Maintain battery at full charge. Proper care will ensure having battery power when
you need it, and will signifi cantly improve the battery life. Failure to recharge lead-acid batteries (within 12-24 hours) is the
leading cause of premature battery failure. Use a multi-stage charger to avoid overcharging. We off er a wide selection of chargers
to fi t your charging needs. If you are using a crank battery to start a gasoline outboard, we recommend that you use a separate
deep cycle marine battery/batteries for your Minn Kota trolling motor. For more information on battery selection and rigging,
please visit minnkotamotors.com.
Never connect the (+) and the (–) terminals of the same battery together. Take care that no metal object can fall onto the battery
and short the terminals. This would immediately lead to a short and extreme fi re danger.
Refer to "Conductor Gauge and Circuit Breaker Sizing Table" in the previous section to fi nd the appropriate circuit breaker or fuse
for your motor. For motors requiring a 60-amp breaker, the Minn Kota MKR-19 60-amp circuit breaker is recommended.
Please read the following information before connecting your motor to your batteries in order to avoid damaging your motor
and/or voiding your warranty.
ADDITIONAL CONSIDERATIONS

Using DC or Alternator Chargers

Your Minn Kota trolling motor is designed with an internal bonding wire to reduce sonar interference. Most alternator charging
systems do not account for this bonding wire, and connect the negative posts of the trolling motor batteries to the negative
posts of the crank/starting battery. These external connections can damage connected electronics and the electrical system of
your trolling motor, voiding your warranty. Review your charger's manual carefully or consult the manufacturer prior to use to
ensure your charger is compatible.
Minn Kota recommends using Minn Kota brand chargers to recharge the batteries connected to your Minn Kota trolling motor, as
they have been engineered to work with motors that include a bonding wire.

Additional Accessories Connected to Trolling Motor Batteries

Significant damage to your Minn Kota motor, your boat electronics, and your boat can occur if incorrect connections are made
between your trolling motor batteries and other battery systems. Minn Kota recommends using an exclusive battery system
for your trolling motor. Where possible, accessories should be connected to a seperate battery system. Radios and sonar
units should not be connected to any trolling motor battery systems as interference from the trolling motor is unavoidable. If
connecting any additional accessories to any trolling motor battery system, or making connections between the trolling motor
batteries and other battery systems on the boat, be sure to carefully observe the information below.
