Battery Charging
Your Mar
C
um system comes with a 3-stage battery charger. This style of charger is proven to
be most effective and easiest to use of all charging systems available. Because this is a 3-stage
charger, there is no danger of overcharging your battery. When properly cared for, a sealed lead
acid battery will last for at least a couple of years. Batteries are made to be used, and they need
to be used to make the most of them. The most important thing you can do is promptly recharge
your battery after each use. Not charging your battery immediately after use is the number one
thing that leads to battery failure.
For safety reasons, it is recommended that you place your system on a flat, hard surface
like cement or tile when charging it, away from any flammable materials. Be sure to
disconnect the charger from the wall when not in use, and avoid leaving your battery
hooked up to the charger for extended periods of time.
When you get home from a trip, put your battery on charge right away and leave it there
overnight, or for around 8-12 hours. Likewise, on the night before an ice fishing trip put it on the
charger again to ensure a good charge. Again, there is no danger of overcharging your battery.
We often talk to people who hesitate to charge their battery after each use for fear that the
battery will develop a “memory” and this will lead to a shortened run time – THIS IS FALSE!!!
ALWAYS CHARGE YOUR BATTERY AFTER EACH USE!!! Be sure to use the charger that
came with your system. Using a larger charger, like you would use on a car, truck, RV, or boat is
likely to cause damage to the battery. There is really no danger of overcharging your battery with
a low amp charger, and most chargers automatically go into “maintenance mode” once a full
charge has been achieved.
TO CHARGE YOUR BATTERY:
Your battery has a wiring harness attached to it that has “piggyback” terminals on it, enabling
you to keep the power cord from the unit attached to the battery at all times, as well as having
the wiring harness with receptacl
e for your charger attached at all times. To charge, simply
couple the end of the charger with the end of the wiring harness. It is normal for a green light to
appear on the charger at this time if the charger is plugged into the battery only. It is also normal
for the light on the charger to be green if it is plugged into the wall. When it is plugged into the
wall and battery, you will see a red LED light appear on the charger. If the light is red, the
battery is being charged. When your battery is fully charged, this red light should change to
green. If it is time to go fishing and the light has not turned green, go fish and try to allow a
longer charging period next time.
Batteries are an expendable item, and must be replaced periodically. The batteries that we use
are the “Sealed Lead Acid” variety, they are 12 volts, and range from 7 to 9 amps. The more
amps the battery has, the longer it will run on a full charge. Your Mar
C
um can be powered off
of any battery that is 12 volts, even a large automotive or deep cycle battery.
If you need to remove the battery, slide the power cord leads from the battery. Remove the strap
that is holding the battery in place and lift the battery out. To replace the battery, place a new
battery of similar specifications into the battery compartment and secure it with the Velcro strap
and re-connect the positive and negative terminals.
