Rechargeable 650 mAh battery pack for HP Smart Array P410 and P212 RAID controllers
This replacement battery pack restores backup write-cache power to compatible HP Smart Array RAID controllers. It is designed for administrators maintaining P410 or P212 cards in server or workstation environments. The proprietary form factor fits the designated controller slot without modification.
As a low-capacity rechargeable cell the unit generates negligible heat and operates silently during normal charge and discharge cycles. Power consumption is limited to the trickle current required to maintain the 650 mAh capacity while the controller is powered on. No active cooling or additional power connections are needed.
The pack is validated only for HP Smart Array controllers P410 and P212. Systems using other RAID adapters or newer controller generations will not accept this proprietary battery size. Buyers who need cache protection for different hardware must source the matching part for their specific controller model.

The pack plugs directly into the dedicated BBWC connector on the controller board; the step most often missed is seating the connector fully until the latch clicks, otherwise the cache backup will not activate.
The rechargeable cell degrades with charge cycles; plan to replace the pack when the controller reports a battery health warning or after roughly three to five years of continuous operation.
The 650 mAh capacity bounds how long the controller can preserve cached data during a power loss; extended outages beyond that reserve will leave unwritten data unprotected.
