The battery is designed for an expected operational life of
5 years.
2 years minimum
Under normal operating conditions, each battery will
undergo a Maintenance Discharge Cycle once every three
months. System software ensures that only one battery at
a time is discharged. Maintenance Discharge Cycles test
the current charge capacity, and ensure the longest battery
life.
Minimum of 200 cycles. Expected operational life of
greater than 500 cycles
The Battery Pack has no calendar-based Expiration or End
of Life date. End of Life is determined by reaching a
minimum charge capacity. This event will be reported by
the HP 3PAR software.
A battery may be replaced by removing the PCM indicating
a battery fault, removing and replacing the Battery from
the PCM, and replacing the PCM within the enclosure.
