Replacement controller battery for IBM DS3512

This 6.6 V lithium-ion pack replaces part numbers BAT-2S1P-2, 69Y2926 and 69Y2927. It is built for the controller modules inside IBM DS3512, DS3524 and DS3500 storage arrays. The 7.26 Wh cell restores cache-backup power so write data survives unexpected shutdowns.

White lithium-ion cell with standard connector

The white housing matches the original form factor and slides into the controller battery bay without modification. A keyed connector ensures correct polarity during installation, reducing the risk of damage to the controller board. Lithium-ion chemistry provides stable voltage across the discharge cycle for consistent cache protection.

Single battery unit in the package

The box contains one 1.1 Ah battery ready for immediate swap-in. No cables, mounting brackets or configuration software are included because the controller manages charging and monitoring automatically. Administrators simply replace the depleted unit and the array resumes cache-backup operation.

Questions about this item

What voltage does the 6.6 V controller battery supply to the DS3500 cache module?

The pack delivers a nominal 6.6 V to the controller's cache-backup circuit, matching the original BAT-2S1P-2 specification.

Will this pack fit inside the IBM DS3512 controller canister without modification?

Yes, it is built to the same physical envelope as the 69Y2926 and 69Y2927 parts used in DS3512, DS3524 and DS3500 controllers.

What is the correct orientation when inserting the battery into the DS3524 controller slot?

Align the white-labelled side facing up and the connector key toward the rear of the canister; the pack clicks in only one way.
