WHAT TO EXPECT FROM YOUR BATTERY EXTENDER!
MAXIMIZES BATTERY LIFE
The Battery Extender is designed to maximize the life of a serviceable
lead acid battery. A serviceable battery is a battery that is not defective
or damaged. This means a vehicle battery will not give you the annual
dead battery surprise when it comes out of storage!
PREVENTS PREMATURE BATTERY FAILURE
The Battery Extender keeps your battery at full charge on a
continuous basis. Batteries not kept at a full charge become sulfated,
which is the main reason for premature battery failure.
MAINTAINS STORED BATTERIES AT FULL CHARGE
The Battery Extender should be used to charge and maintain all
starting and deep cycle batteries in storage or that don’t receive daily
use. Some examples are: automobiles, boats, race cars, campers,
RV’s, 4 wheelers, motorcycles, personal water craft, farm machinery
(tractors, combines, etc.), heavy equipment, rental equipment (trucks,
compressors, portable signs, bulldozers, stationary pumps, etc.),
and any equipment that receives occasional use or is in storage.
The Battery Extender is also fully compatible with gelled electrolyte
(gel-cell) batteries (sometimes used in place of liquid electrolyte
batteries in many heavy duty applications). (DO NOT USE WITH DRY
CELL, NICKLE CADMIUM, NICKLE METAL HYDRIDE OR SIMILAR
BATTERIES. Refer to the enclosed instructions.)
NOTE: Never use the Battery Extender in a boat or water craft.
Always remove the battery from the boat or water craft and
use the Battery Extender on shore.
VALUABLE PROTECTION
The Battery Extender provides full off-season protection for seasonally
used batteries. It keeps your stored batteries ready for their next use.
This means a serviceable battery will not give the annual dead battery
surprise when it comes out of storage!
PROTECTION FROM COMPUTER DRAIN
Cars are often equipped with computers that require continuous
battery power to maintain data in memory. The Battery Extender’s
superior circuitry automatically delivers the correct charge to
compensate.
LONG LASTING PERFORMANCE
The Battery Extender has been designed and manufactured in America
to provide superior performance from the High Tech housing to the
last internal detail. Quality is built in and assured with circuit burn-in,
computerized testing and inspection. Care in handling and occasional
cleaning of the leads and housing will help keep it looking like new, and
give you many years of satisfaction.
Checks Each Battery’s Condition
The Battery Extender will determine the worst batteries that are
sulfated and that have bad cells. The battery can be replaced without
unnecessary charging.
Battery Warmer
The Battery Extender will keep a battery warm and ready for full use on
cold days.
OVERLOAD AND PROTECTIVE DEVICES
The Battery Extender is equipped with two overload protectors. In the
event of minor overloads, power will be reduced to a safe level to allow
continued use in maintenance mode only. The second protector will
activate in the event of major overload and completely turn the unit
off. The second protector is permanent and must be repaired at the
factory.
Always keep your Battery Extender clean and looking like new! Unplug
the Battery Extender, and use a slightly dampened cloth to clean the
housing and lead sets. Use no solvents or soaps.
IMPORTANT!
A clean battery and battery terminals insure proper operation of the
Battery Extender and the vehicle charging system. Dirty terminals may
put a constant slow drain on the battery. If your battery and terminals
have a white or blueish crust on them, your charging system may be
having problems. Have the vehicle electrical system checked by a
qualified automotive service technician.
