From the Promise VTrak E-Class 4x 1TB, "This cable-less system design includes a single RAID controller with 2GB battery backed onboard cache, redundant hot-swappable power supplies and cooling units." So yes there is cache battery backup (72 hours)

If your asking whether it ships with batteries, it should ship all ready to go i.e batteries not sold separately. Looking at the non Apple qualified version on the Promise site, the 72 hour cache battery carries a 1 year limited warranty; while the hardware is covered for 3.
