If you want a better comparison, find the curves and compare them. And the
weights.
And the size. You might be surprised to find that there is little
difference
in the
capacities. Chemistry is chemistry.

Chemistry determines the voltage, but the capacity is set by geometry and
design details. I know that Eagle-Picher has been working on inovative
woven mat designs to increase the capactiy of SLA batteries; perhaps the
unusually high capacity battery (for its size) cited earlier in this thread
uses this technology.
