i have not researched your application , but there are batteries then again there are batteries ...

if the battery is pretty new and crapped out take back to a different place than where you got it that carries the same line and present it for compensation .
. if i was running ICE [internal combustion engine] +alternator delete [ or any application where draw is expected w/o concurrent charging] i would have TWO batteries. one a small starting battery and the second a larger deep cycle battery. some wiring and switching circuits , good gauges to measure the level of batter charge.
the small starting batter only used to start and run when charging was available, the deep draw all other times ..

i think there should be off the shelf circuit designs available , it is what i would expect in a well designed RV that had a 12V system in the cabin to run lights , food coolers .. what not

install a battery "isolator." An isolator is an automatic battery switch that allows both batteries to be charged while the engine is running, but isolates the main battery, protecting the charge from being drained by running accesso

there are two types of lead acid batteries (along with 3 sub categories); The two main types are Starting (cranking), and Deep Cycle (marine/golf cart). The starting battery (SLI starting lights ignition) is designed to deliver quick bursts of energy (such as starting engines) and therefore has a greater plate count. The plates are thinner and have somewhat different material composition. The deep cycle battery has less instant energy, but greater long-term energy delivery. Deep cycle batteries have thicker plates and can survive a number of discharge cycles. Starting batteries should not be used for deep cycle applications because the thinner plates are more prone to warping and pitting when discharged.
