There are two types of PCMs:
• 580 W PCM - Used in HP M6720 and HP M6710 drive enclosures
• 764 W PCM (includes a replaceable battery pack) - Used in controller node enclosures
The following table provides the technical specifications of the replaceable battery located inside
the 764 W PCM.

The battery is designed for an expected operational life of
5 years.
Design Life
2 years minimumShelf 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.
