Battery

The battery must be charged for six hours before using it the first time. If the battery completely
discharges, recharging may take up to 18 hours. When not in use, it is recommended to keep the

battery plugged in to maintain a maximum charge and extend the battery life. The charger will not
overcharge the batteries.

General Battery Warnings

• Do not connect accessories to the battery; this will cause premature battery failure.

• Unauthorized modification could create a hazardous condition and result in serious injury.

• Batteries contain sulfuric acid, which can burn eyes, skin, clothes, etc. Use caution! Always wear
gloves when working with batteries. If contact occurs, flush immediately with water and get medical
attention. Protect surfaces from battery damage by placing batteries on rubber or plastic surfaces.

• Never place a battery near an open flame or heat - it could explode.

• To prevent electrical shock, do not touch non-insulated parts of the charger output connectors,
battery connectors or battery terminals. Do not use connectors that are cracked, corroded, or do not
make adequate electrical contact. Use of damaged or defective connectors could result in fire or
electrical shock.

• Keep sparks, flame and smoking materials away from batteries.

• Batteries can supply a large amount of current. Do not wear jewelry or watches when working on
the batteries as an accidental shorting could occur and cause severe burning.

General Charging Warnings

• Use only the Magliner 24V charger designated for use with the Motorized U-Boat. Charge using
a grounded 110V electrical outlet.

• Do not operate the unit when the battery charger is plugged in.

• Do not expose charger to rain or snow.

• Store the charger in a dry, clean place.

• To prevent risk of fire, use the charger only in a dry, well ventilated room without flammable
fluids or explosive gases.

• Make sure the cord is located such that it will not be a trip hazard or otherwise subject to
damage or stress.

• Do not operate a charger with a damaged cord or plug – replace immediately.

• To reduce risk of electrical shock, unplug the charging unit from the AC power supply source
before attempting any maintenance or cleaning.

• Always use battery chargers supplied by Magline, Inc. Other battery charging units could cause
damage to your batteries or personal injury.

• To avoid damage to battery charger connectors and cords, disconnect by grasping the plug body
and pulling it straight out of the outlet or receptacle. DO NOT pull on the cord. DO NOT twist,
rock, or pull the connector sideways.

• The metal tip on the end of the plug may be hot when it is first unplugged.

Battery Life

The Motorized U-Boat is Motorized by two 12V, 12Ah AGM lead acid non-spillable batteries.*
A fully-charged battery will last at least one typical route delivery shift; however, extreme
temperature ranges and extreme loads can have an effect on the amount of power available
during one charging cycle. You will know that your batteries need replacing when you notice
diminished range or operational time.

*Battery has a warranty of six (6) months
