The battery in RAID adapter card only barely addresses the issue, I don't care how long it lives.
But the comment also addressed "RAID enclosures," which I take to mean storage servers that use RAID technology. Those, if they are at all serious, have batteries that power the disk drives as well, and only for a few seconds -- long enough to finish the write. It's not about backup power, it's about a system in which data is always consistent and persistent, even if someone pulled a power cord at some point.
