These are flooded alkaline batteries, just like the NiCad ones. Not as good
of energy density though, so I think they actually end up being near as
heavy or even heavier than lead acid. No problems with deep cycling, and
very long. Somewhat sought after for off-grid PV systems, but not so great
for a mobile application, in my mind, because of the size and weight.
Having said that, without seeing the exact specs, maybe the weight isn't as
bad as I think, if these particular ones were designed for an EV application
to begin with.
