provide electric power when vehicle stationary
When does the Battery provide power
When a large amount of power is needed
When electrical systems need power to function
The battery provides power when the engine is stationary
The battery provides power when the engine is running
What active materials are the battery plates made of?
carbon and ferrous sulphate
positive is lead peroxide and negative is porous lead

A battery discharging occurs when
A load is not present
A load is placed across the battery terminals
when the engine is running
As required, if the battery is in working order
Charging occurs as ?
Current flows out of the battery
Current flows into the battery
without any requirement
provided there is a fuse
Electrolyte chemical reaction when discharging
Electrolyte hydrogen combines with positive plate oxygen to form water
Electrolyte sulphate combines with lead on plates to form lead sulphate
Current flow reverses chemical action
Electrolyte chemically reacts with lead plates.
Charging batterries chemical reaction changes
Electrolyte chemically reacts with lead plates.
Sulphate is forced back into electrolyte and combines with hydrogen, while oxygen returns to the positive plate to form lead peroxide.
Process continues while voltage is applied, until all lead sulphate is converted
Electrolyte sulphate combines with lead on plates to form lead sulphate
The unit of measurement for pressure is
volts
amps
ohms
watts
