Battery
The battery must be charged for a minimum of 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 acid-safe plastic
surfaces.
• Never place a battery near an open flame or heat.
• 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.
General Charging Warnings

• 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.
• 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.
• 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 Dewar Cart is powered by a 36V system using three 12V batteries connected
in series.* A fully-charged battery pack will last at least one typical day; 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

Battery Care
• Store and charge the Motorized Dewar Cart at temperatures between 50 and 100 degrees F.
• Always keep the machine on charge. Batteries stored for long periods of time will selfdischarge and may get so low, that the charger cannot recharge them.
• Keep the terminals clean and tight.
• Handle the batteries with care.
• The batteries may require 4-10 charge/discharge cycles until batteries charge up to their full
potential.
• DEEP DISCHARGE ON A CONTINUAL BASIS WILL SHORTEN THE SERVICE LIFE OF THE
BATTERIES.
• Battery performance may be reduced when operating in temperatures less than 40 degrees
F. You should anticipate a range reduction by 50% or more when operating at temperatures
below 32 degrees F.
