you are interested in fishing. The Quest HD L is small enough to hold in your arms while walking
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 4-6 hours. Likewise, on the night before an ice fishing trip, put it on the charger again,
just to make sure. 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 EVERY 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 always, as well as having the wiring
harness with receptacle for your charger attached always. 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
now 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 just 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 Lithium Iron Phosphate (LiFePO4) variety, they are 12-volt 10-amps. The more amps the
battery has, the longer it will run on a full charge. Your MarCum can be powered off any battery
that is 12 volts, even a large automotive or deep cycle battery.
If you are having difficulty with the charging process, please see the Charger Troubleshooting
section on our website, www.marcumtech.com/support.
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.
