Which cache battery service do you need?
If your array is reporting a failed, missing or expiring cache battery, send us the part number and we’ll come back with a fixed-price repair quote. If you can’t run with write cache disabled while it’s away, ask for an advance-exchange unit and we’ll ship one from stock first. Not sure which battery you’ve got? Tell us the array model and we’ll work it out.

The cache battery faults we see every week.
If your array is flagging its cache battery, it’s usually one of these. Most are repairable at component level.
Battery failed or missing
The controller reports the cache battery as failed, missing or not detected — often a cell, connector or board fault rather than a dead pack.
Write cache disabled
With a weak battery the controller drops to write-through mode to protect your data, and performance falls with it.
Won’t hold charge
The battery charges but fails its learn or capacity test. Usually tired cells — we replace them and recalibrate the board.
End-of-life warnings
The lifecycle counter says the battery is due for replacement. We rebuild it and reset the flags so the array reports it as healthy.
Swollen or leaking cells
Physical damage from age or heat. Cells replaced, housing checked and the pack load-tested before it goes back.
Charging or board faults
The cells are fine but the pack won’t charge or report correctly. Diagnosed and repaired on the board.
Four steps from failure to fixed.
The same process across every OEM platform. Predictable, tracked and quoted before any work begins.

Questions we get asked.
Straight answers on turnaround, warranty, advance exchange and what to send us.
How long does a cache battery repair take?
Our standard turnaround is 5–7 working days from receipt. If you can’t wait, we can usually ship an advance-exchange unit from stock first.
Is a repaired battery as good as a new one?
We replace the cells, recalibrate the board and reset the lifecycle flags, then load-test every battery for 8 hours before it leaves. It’s covered by a 12-month return-to-base warranty.
Will my array recognise the repaired battery?
Yes. It goes back in exactly as your original did, and because the lifecycle flags are reset, the controller reports it as healthy.
Can you repair batteries for end-of-support arrays?
Yes — including HP EVA and older Storwize models where a new OEM battery is hard to find or no longer sold.
What does advance exchange mean?
We send you a replacement battery from stock before yours comes to us, so you’re not running with write cache disabled while it’s being repaired. Subject to stock.
What do you need to quote?
The battery part number and the array model. We’ll come back with a fixed-price repair quote and advance-exchange availability.
Battery not listed?
