540 Cold Crank Amps, and 36Ah reserve capacity...for under five pounds!! Expensive, yes ($350), but you are shaving 5-8lb off your overall and FWF weights for that money, which is not insignificant.

Buy two of them and put them in parallel. You still have 36 amp/hr and 540CCA at a total weight of less than 3 lbs and save a $100.

I'm noticed that too...I'm assuming it's an Asian company and that is a typo.
EDIT: whoops, from post above I am dead wrong.
