Battery
Specifications
- Chassis
The chassis battery operates only chassis and engine
functions. The chassis battery is a crank type battery,
producing the high amperage needed to start the engine.
Engine starters initially require a large amount of cur-
rent to crank an engine. Initial starter amperage draw
exceeds 1200 amps. The type of application in which
the engine battery is used differs from the house battery
application. The engine battery state of charge remains
consistent. Maintenance is still required with an engine
battery. Regular electrolyte level checks and hydrome-
ter readings should be performed. High electrolyte con-
sumption, or inconsistent hydrometer cell readings,
may indicate a charging system problem. Perform a
charging system and current draw check if the battery is
exhibiting abnormal hydrometer readings.
NOTE: Replacement batteries should have the same cold
cranking amp (CCA) rating.
