After looking again at some of these batteries I suspect the AH rating you listed is actually referring to something else maybe cranking amps etc...
Im thinking these are going to fall into the 90-100AH rating class and weight around 70lbs each... The 150Ah batteries I was looking from TROJAN T-1275 produced 150 AH each and weighed at 85lbs...
That many AH's will most likely weigh around 250lbs each for wet cell batteries...
ADDED NOTE: Havent looked at AGM batteries verses wet cell batteries - I may be out in left field big time haha...
