RAID card has failed on recondition for second time in two years. is this the normal lifespan?
Please look at my post: https://discussions.apple.com/message/22401775#22401775
It is the normal time period for this. But it does not mean that you have to replace the battery. I assume a firmware bug on the card. Make it powerless (also disconnect the battery) for a few minutes and you gain another year.
