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. 24 Power Requirements

Capacity
The battery is designed for an expected operational life of
5 years.
Design Life
2 years minimum
Shelf Life
Under normal operating conditions, each battery will
undergo a Maintenance Discharge Cycle once every three
Maintenance Discharge Cycles
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
Charge/Discharge Cycles
The Battery Pack has no calendar-based Expiration or End
of Life date. End of Life is determined by reaching a
Expiration/End of Life
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.
