Section 9
Battery and Battery Charger
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.
SAFETY INFORMATION
All batteries used in electric vehicles can explode!
Always wear full face shield when working on or near
batteries. Hydrogen fumes are a natural byproduct of
charging and discharging and are extremely explosive.
Do not smoke around electric vehicle batteries. Keep
sparks and flames away from batteries. Battery
charging should only be done in a well-ventilated area.
Refer to Section 9-Batteries for details.
Batteries contain acid which can cause severe burns.
Avoid contact with skin, eyes, or clothing. Wear full face
shield and rubber gloves when working on or near
batteries.
Do not attempt to charge a battery if it is frozen or if the
case is bulged excessively. Frozen batteries can
explode. Dispose of battery.
