I guess "density" would mean mass to a mechanical engineer and energy density to an electronics engineer, at least in the context of a battery?
Curiously, I looked it up - lead and aluminum are about equal, as far as buying it on the stock market - $0.8 to $1 per pound over the last year. I always thought aluminum to be a far more valuable metal.
Maybe these batteries will have merit if the retail costs are similar to AGM or SLA per mass-unit and per energy-unit (whatever they may be :)
DEKA - East Penn rates the AGM batteries I bought at a huge number of cycles as well, using 1 cycle = 10% or less discharge with immediate recharge. Personally, my definition of a cycle is 50%-80% discharge, with 6-12 hours elapsed before a recharge.
