What I have observed with my Surplus Telecom acid rich Deka.
I can set the voltage to what ever on my 30 amp Mega Watt, but I usually keep it at 14.4V. Battery is rated about 150 to 160 ah for 20 hour rating.
Battery takes what it takes for current. Rarely will it do over 20 amps recharge rate, at 14.4V. This Mega Watt recharge, 1x a week when boondocking off the grid, keeps the battery in good shape. When the battery won't take more than 0.75 amps /hr on the RC watt meter that is in line with the megawatt, I shut things off. Battery flat out works, very very well. Let it suck up big amps from the meanwell, and the generator, 1x per week, between daily solar panel recharges. Get it really fully charged, by what ever means you must use, to keep it from sulphating.
