State-of-Health (SOH)
A factor that aects a battery’s ability to crank an engine is its
actual condition or State-of-Health (SOH). It is a measure of
the battery’s condition relative to a fresh battery.
A State-of-Health problem is most often the result of normal
wear-out mechanisms, which are dependant on vehicle
needs, climate, and operating conditions. This results in
irreversible physical and chemical changes until eventually
the battery can no longer hold a charge and supply the
power necessary to start the car and provide auxiliary power
to the electrical system.
As the battery approaches end of life, its deterioration
accelerates, until it nally fails to start the vehicle. Before
failing, the battery may start the vehicle under normal
conditions but may not be able to operate in more extreme
conditions. Extreme heat or cold could expose a weak
battery and cause it to fail.
