lead acid batteries can't be discharged more than 50%... or they can, but after you go below 50% it will never fully charge. I'm not sure what the real number is, but figure a round number this way;
drain to 40%, max charge is now 80%
drain to 30%, max charge is now 60%
drain to 20%, max charge is now 40%
get below 15%, battery may never hold a charge.
Most people put in battery disconnect switches so the battery can't drain from ghost power draws. A lead acid battery will not hold a charge, even with no draw, but its slow. You are probably looking at needing a charge every 6-8 weeks to keep it above 50%. Battery quality plays into that, outside temp, overall weather exposure.
