NICKEL-CADMIUM STARTING SYSTEM SERIES
92000 and 110900 ENGINES
This Briggs & Stratton starter system consists of a starter
motor and a starter switch, a wiring harness and a nickel
cadmium rechargeable battery and battery charger.
When the ignition key is turned to START, the battery
supplies power to the starter motor, cranking the engine
similar to the system used in an automobile. Under
normal conditions, the battery will provide 40 to 60 starts
before recharging is necessary.
NOTE: Some equipment manufacturers use a battery
and charger of a different style than illustrated. In such
cases, follow the equipment manufacturers
When the battery needs recharging, the charger is
plugged into a 120 volt AC household outlet, and then
connected to the battery. The battery will be fully
charged within a 14 to 16 hour period. It is not
recommended the battery be recharged if temperatures
are below 40° F (4° C). Continual charging may be harmful
to this battery. For best results, charge the battery within
temperature limits of 400 F (40 C) to 1050 F (400 C) and
after each use of equipment. When long periods of
storage are encountered, the battery should be charged
over night every two months. This type of battery will
lose its charge when not in use. This will shorten battery
NOTE: The battery is shipped in a discharged state and
must be charged 14 to 16 hours prior to its initial use.

NOTE: If a starting problem is encountered, the engine
itself should be thoroughly checked to eliminate it as the
cause of starting difficulty. It is a good practice to check
the engine for freedom of rotation by removing the spark
plug and turning the crankshaft over by hand, to be sure
it rotates freely.
