I'm about to replace my 12v deep cycle battery
and I'm considering a golf cart battery
. From the specs for these batteries, they seem to offer greater amp/hours for a given size and according to the marketing hype, can be cycled almost twice as many times as conventional deep cycle batteries. The initial cost is greater, but long term, it looks like the cost per amp/hour is significantly less for the GC battery
Several of the manufacturers offer 12v versions, although it looks like earlier versions were 6v. I'm wondering if the newer 12v versions are truely "golf cart" quality or just re-purposed deep cycle batteries.
