The protocol page at http://www.networkupstools.org/protocols/apcsmart.html
just says under 'x' that it's a "Writable variable" and "This holds whatever
the user sets in it, much like the UPS local id variable".  The SmartSlot 
management card also has a menu entry to set the battery date.

Having said that, we have never bothered setting the date when we have 
changed batteries.
