Firefly has named the foam technology inside the batteries Microcell™, and says they are:
changing the rules of the road [...] Compared to lead plates - one of the main components of most conventional truck batteries – patented Microcell technology delivers longer service life, increased energy efficiency and better performance under extreme conditions. [...] Oasis' unique design resists sulfation and corrosion (two of the primary causes of failure in lead-acid batteries), while dramatically increasing the surface area within the battery, resulting in greater energy capacity, faster recharges, and deeper discharge capability...
Looks like we only have a half year or so to see for ourselves.
