Though the group size is interesting and does indicate a lot of things Lead Acid batteries come in several "Flavors" as it were.
For example
Flooded wet (You add Distilled water from time to time)
Maintenance free (No adding anything)
AGM. (Likewise plus some other advantages)
None of that matters to this post
Another division
Starting
MARINE/deep cycle or MARINE/rv
DEEP CYCLE
Pay attention to case in this part (UPPER/lower)
Starting batteries are designed to put out a lot of current but not all that any amp hours. They like to be 80% full or better..
MARING/deep cycle or rv are starting batteries but with a nod to Deep cycle, they should be kept above about 75% State of charge
DEEP CYCLE can go down to 50 ... Some lower
THe GC-2's are likely DEEP CYCLE (GC = Golf Car)
THe rest are not.
