3Ware BBU Replacement

[ratdude747]

The BBU in my 3ware 9500S is reportedly dead...

Has anybody had luck with 3rd party batteries? Or should I save up for a $$$ OEM one?

OEM. You'll pay more for the batt, but it will save a lot of aggravation. The cheap shinese one I tried lasted about 2 months. Replaced it with an OEM, its been fine since, going on 3 years.

Did the dead batt throw the controller into panic mode, and disable all write caching? Mine did on both controllers, it performed like absolute crap till that silly batt was replaced.

It causes the status screen on bootup to display "bbu status: failed battery". Not sure if write caching was affected.

edit- I thought I had a BBU pic, but I don't (that's uploaded and on a camera I can access)... so google it and you'll see.

I hope that it's not just a sensor like laptops sometimes falsely reporting a bad battery.

Re: 3Ware BBU Replacement

Still haven't replaced the battery

from the stock image on LSI's listing for a $60 replacement battery, it's an LI103450E battery, which also was used by dell for stuff.

I know OEM is the way to go, but $60 is out of budget. (I know, I should have used a consumer crap board with no RAID card blah blah blah...)

Edit- it's a 3.7V 1800mAH cell... I wonder if I could get a cell in the same form factor for cheaper and solder on the wires from the old one?

edit- made an offer:

it's got a newer battery , and given the hackjob my card is (been resoldered a few times), I figure that may be a better deal?

Re: 3Ware BBU Replacement

why not soldering in any random li-ion battery you have laying around? just another somewhat functional battery, will do the job. If it is a totally different shaped one it is actually an advantage, as you can zip-tie it ti the board, take a picture, and upload it to ghetto mod thread.

somebody will definitely say: "but it is li-ion, it can explode, i've seen macbooks going on fire"

Re: 3Ware BBU Replacement

Why? I'm not sure if the charging circuit will like a different battery. I have done this for other RAID cards (my GF's dad is the IT manager at Caterpillar's Lafayette Engine plant, and he had me "fix" some blown RAID batteries)... but in that case, it was a was a like for like battery swap with the controller on the battery. With my card, the controller appears to be in the BBU module itself, the battery a raw cell.

It's not like I have a 3.7V battery sitting (well, i might in a dead cellphone, maybe).
