Also (forgot that part of your question):
I've seen support these battery change reqs in the past if you have a valid support contract for the host that uses the Array. Best bet is to call in a ticket with Sun and then have them tell you whether it is supported or not.
Unless it's hopelessly EOSL, they usually do send in replacement parts per contractual agreement.

Yeah, they're designed to do hot-swap on the battery. In fact I know many admins that still do that on their out-of-support models.
But sun had a number of failures in the field when this was done in the past (very low as a percentage, but still quite a few). So the current procedure requires the shutdown.
