Okay you are mixing things up here. What you want is a TRUE, DEEP DISCHARGE BATTERY. Not a engine staring battery and not a "dual purpose" (marine) battery. All golf cart batteries are designed as deep discharge.
Most golf cart batteries are "flooded"
(liquid electrolyte) but there are AGM
(non-liquid electrolyte) available, typically at a higher cost. IMHO, AGM batteries are NOT worth the additional cost.
And as stated hundreds of time before, the best bang for your buck is flooded golf cart batteries from Costco or Sams Club.
