I have a Dell 2950 server with a Perc 5/i RAID card installed. Recently, I have been getting a warning that the BBU is no longer providing sufficient charge for it to function properly. This was not a terribly serious concern until we had a second unit of similar age show the same error. I know that I can buy a BBU off of eBay, but my concern is that the battery there will be just as old and possibly even more heavily used. Is there any company anyone knows of that refurbishes BBU's? Or for that matter any way to purchase a replacement from Dell themselves? Ideally I would like a BBU with a new battery not one just as old as the one's I am replacing.
