BATTERY & WIRING INSTALLATION

ADDITIONAL CONSIDERATIONS

ADDITIONAL ACCESSORIES CONNECTED TO DOWNRIGGER BATTERIES
Significant damage to your Cannon downrigger, your boat electronics, and your boat can occur if incorrect connections are made
between your downrigger batteries and other battery systems. It is recommended to use an exclusive battery system for your downrigger.
Where possible, accessories should be connected to a separate battery system. Radios and sonar units should not be connected to any
downrigger battery systems as interference from the downrigger is unavoidable. If connecting any additional accessories to any downrigger
battery system, or making connections between the downrigger batteries and other battery systems on the boat, be sure to carefully
observe the information below.
The negative (-) connection of an accessory device must be connected to the negative terminal of the same battery that the downrigger
negative lead connects to. Connecting to any other downrigger battery will input positive voltage into the "ground" of that accessory,
which can cause excess corrosion. Any damage caused by incorrect connections between battery systems will not be covered
under warranty.
AuTOMATIC JuMP START SYSTEMS AND SELECTOR SWITChES
Automatic jump start systems and selector switches tie the negatives of the connected batteries together. Please see a qualified marine
technician if installing your Cannon downrigger with one of these systems or a selector switch.
SELECTING ThE CORRECT BATTERIES
The downrigger will operate with any lead acid deep cycle marine or Lithium 12 volt battery/batteries. For best results, use a deep cycle
marine battery. Maintain battery at full charge. Proper care will ensure having battery power when you need it, and will significantly
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 offer a wide selection of chargers to fit 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
Cannon downrigger.
