Replacement Battery for IBM V7000

This 9.9V lithium-ion cell provides 24.8Wh capacity for the IBM V7000 backup system. It replaces part numbers 31FR27/66, 85Y5898, 85Y6046, 00AR300 and 00AR301. The black unit ships new and ready for installation.

Practical Limits of Li-ion Backup Cells

Lithium-ion chemistry degrades over time regardless of use cycles. A 24.8Wh pack at 9.9V delivers limited runtime during power loss events. It cannot support extended outages or high-draw components beyond the controller cache.

Straightforward Swap with One Common Pitfall

The battery installs directly into the V7000 enclosure without tools. The main risk is inserting the connector with reversed polarity, which prevents the system from recognising the new cell. Buyers needing hot-swap redundancy or higher capacity should look elsewhere.

Questions about this item

Which part number should I select for my IBM V7000?

The battery carries part number 31FR27/66 and replaces NEX-900826, 85Y5898, 85Y6046, 00AR300 and 00AR301; choose the one that matches your service label.

What runtime does the 24.8Wh capacity provide in a V7000?

At 9.9V and 2.5A the pack stores 24.8Wh, giving roughly one hour of backup at a 2.5A draw; actual time varies with controller load.

What interface does the 31FR27/66 use and what does it limit?

The battery connects via the V7000's proprietary backup-battery connector, limiting use to that controller's cache-backup circuit.
