The faster you discharge a lead acid battery the less energy you get (C-rating) Recommended discharge rate (C-rating) for lead acid batteries is between 0.2C (5h) to 0.05C (20h). Look at the manufacturer’s specs sheet to be sure. Formula to calculate the c-rating: C-rating (hour) = 1 ÷ C
Most lead batteries will be OK at 14.5 V for a few hours (but make sure you read-up for more information on your specific battery type). If you limit the voltage to, let's say, 13.6 V, then the battery may last a long time. Like several years. This is just a quick answer.
Lead acid batteries are actually the most complicated of all the common rechargeable battery types. They have lots of little quirks you have to pay attention to if you want to get the best possible life out of them. However, they do reasonably well in float service and are much cheaper than any lithium or nickel chemistry battery.
To prolong the lifespan of a sealed lead-acid battery, try to limit deep cycling and never deep-cycle starter batteries, otherwise you will struggle to get them started again. Apply full saturation on every charge and avoid overheating.
