Deka, one of the worlds largest lead acid battery manufacturers, says 30% of C20 for their true deep cycle batteries. That's double what you are stating above and what I've been doing for 30 years. I average 5 to 7 years out of 6 volt GC2 batteries. I've ran them for decades in my scissor lifts with daily charge/discharges. Always charged at a much higher rate than you state above.

You do not "push" amps into a lead acid battery. They "pull" amps as needed per depth of discharge and quickly reduce their draw as you begin charging. I've run 470 amp hours of 6 volt GC2 in campers for many years. I have 120 charging amps available if needed but rarely see them pull more than 80 for a brief time before they start dropping. True deep cycle lead acids are absolutely capable and recommended to be charged at 30% C20.
