What does the battery exactly do in this card? I know it "protects" the write cache, but a little more in details?

I have 2 cards and both batteries failed, I have forced on the write cache and everything seems to work fine, what is the risk in running my mac like that????
I use it mainly for recording with nuendo, but my standard session is about 100 tracks.

    If the Mac loses power during a write to the RAID, the battery will save the cache until either power is restored and the write is completed, or the battery eventually dies and the write cache is lost. The battery should last 72 hours, which in theory gives you enough time to get power back to the Mac Pro.
