That really isn't their concern, because they're not marketing to the automotive sector, where weight is an issue.
I think if weight were the primary concern with vehicles they woudn't still almost exclusively favor the heaviest optopn available (lead acid) and would be going with something more like lithium.
Lead acid isn't chosen for its weight - it's chosen for its cost, energy density, resilience to vibration, and cranking amps.
