The battery maintains the contents of the cache. If power were to fail before a write were completed, the contents would be able to be flushed to the drives when power is returned. Potentially, if the system the drives/cache are in a system that goes completely toes up, the cache with battery and the drives can be transferred to a similar system to complete the write.
