4.0 ELECTRIC SYSTEM
4.1 IMPORTANT INFORMATION
The type of battery used in a Columbia vehicle has a service requirement which is quite different from that
of an automotive battery.
The electric vehicle battery supplies all of the power to drive the vehicle. During operation the power
stored in the batteries is expended. While the amperage drain rate can vary greatly depending on the
type of service, the duration of use and the number of "starts" and "stops" made during a day, the
batteries nevertheless progress through each duty cycle from "fully charged" to an almost depleted state.
This type of service is known as "deep cycle" service and electric vehicle batteries are specifically
designed to handle this type of service.
Proper performance of your Columbia vehicle can only be obtained from specified deep cycle, electric
vehicle batteries.
PLEASE REVIEW IMPORTANT DANGER, AND WARNING STATEMENTS WHEN WORKING
AROUND BATTERIES AND CHARGING SYSTEMS!
Always remove key and disconnect battery pack before servicing or repairing the vehicle. See
Section 4.9.
Always wear full-face shield when working on or near batteries.
All batteries used in electric vehicles can explode! Batteries produce explosive hydrogen gas at
all times, especially, during charging or discharging. Ventilate area when charging batteries.
Do not attempt to charge a battery if it is frozen, or if the case is bulged excessively. Frozen
batteries can explode! Properly dispose of the battery.
Do not smoke around batteries. Keep sparks and flames away from batteries and the charging
area. Use care to prevent an accidental arc which could cause an explosion. Use only approved
insulated tools, remove jewelry such as rings, watches, chains etc. and place an insulating
material (wood, plastic, rubber etc.) over all battery connections.
Never add acid to a battery.
Battery acid is poisonous and can cause severe burns. Avoid contact with skin, eyes, or
clothing.
ANTIDOTES:
EXTERNAL: Flush with water. Call a physician immediately.
INTERNAL: Drink large quantities of milk or water. Follow with milk of magnesia or vegetable
