You are simply informing some new campers of how to shorten the useful life of their batteries...simply.
Hey new campers out there. Do not let your batteries get below 50-percent of full charge, it will shorten their lives.
true for most marine batteries but NOT true for most GC 6v. They are a true deep discharge and designed for many cycles well below 50 percent. Trojan gives cycle life down to 25 percent SOC or 75 percent DOD at over 500 cycles. I can verify on two sets, that have been discharged to 25 percent SOC several hundred times that this is accurate. One set just went bad after 14 years, the other set of 4 is still going strong after 9 years and probably 200 discharges down to 25 percent SOC. Golf carts do that constantly.
Just don't leave them discharged for more than a week before getting them fully charged again.
Yes, discharging to 50 percent on a GC does give more cycle life, but how many RV'rs need or even see 500 cycles to 25 percent let alone 1500 cycles to 50 percent
