Will there be any benefits in size/footprint when compared to lead-acid batteries?

Yes, lithium-ion batteries offer higher energy density vs traditional lead-acid batteries, therefore many of the 9PX lithium-ion UPS solutions will provide more runtime in the same amount of space. Models like the 9PX may maintain a 2U UPS form factor with more runtime, while extended battery modules (EBMs) may provide somewhat similar runtime but shift from a 2U to a 1U form factor.
