IBM X236 X346 RAID controller battery

This lithium-ion replacement battery fits the array card used in IBM X236 and X346 servers with 7K SCSI U320 RAID controllers. It restores cache-backup power so write data survives unexpected shutdowns. System administrators maintaining these legacy platforms will find it a direct-fit part. Buyers needing batteries for other RAID cards or newer server generations cannot use this unit.

Replaces OEM part numbers 39R8804 71P8644 90P5245

The package includes one battery that matches the original PN 1496729-00-R and BAT-00011-01-A specifications. Swapping it lets the controller retain cached writes during power loss without firmware changes or driver updates. No cables, brackets or software are bundled, so the only change is the fresh cell itself.

Simple plug-in install inside the controller card

Power down the server, open the chassis, locate the array card and unclip the old battery before pressing the new one into the same socket. The black lithium-ion pack keyed to the connector prevents reverse insertion. The only common issue is forgetting to reseat the card fully after the swap, which leaves the controller offline at boot.

Questions about this item

How often does the lithium-ion cell in this BAT-00011-01-A need replacing?

The lithium-ion cell is a consumable part; replace it when the RAID controller no longer holds its cache through a power loss, typically every few years of continuous service.

What is the first limit reached when the array card runs under sustained load?

The battery's ability to back the 7K SCSI U320 RAID controller's cache is the limiting factor; once its charge depletes, write-cache protection is lost.

Does the battery generate noticeable heat or noise during all-day operation inside the X236 or X346?

No, the lithium-ion pack is a passive component with no moving parts and produces negligible heat or noise while installed in the array card.
