"69Y2926 is the backup battery module listed in the parts tables for the IBM System Storage DS3512 and DS3524 in IBM's DS3500 and EXP3500 Installation, User's, and Maintenance Guide (GA32-0952-07).
IBM describes it as a sealed, rechargeable lithium ion battery that, on a power failure, backs up the controller cache so its contents can be written to flash memory.
The guide says to replace only the failed battery unit, and that the green Battery charging LED on the controller is on when the battery is fully charged and flashes while the battery is charging or running a self-test.
The guide covers the DS3512 and DS3524 storage subsystems and the EXP3512 and EXP3524 expansion enclosures; the backup battery module appears in the DS3512 and DS3524 parts listings.
Fit check: a DS3512 or DS3524 RAID controller and 69Y2926 on the battery label. For IBM Storwize V7000 power parts see 85Y5898 (V7000 battery) and 85Y5847 (V7000 PSU)."
