Lead–acid batteries with a lot of free acid and thicker plates gain more capacity at low discharge rates. The reason is that, at high rates, fresh acid cannot get inside the plates fast enough and the capacity is limited by the amount of acid available.
The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them. The most important lesson here is this:
Lead acid batteries should never stay discharged for a long time, ideally not longer than a day. It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating.
At lower rates acid can diffuse to the plates during the discharge and maintain a more adequate supply of acid to the discharge reactions. The AGM type of sealed batteries have considerably less free acid than do open or gel batteries, and therefore do not show much capacity increase at low discharge rates.
This means that if you (accidentally) short-circuit a lead acid battery, the battery can explode or it can cause a fire. Whatever object caused the short-circuit, will probably be destroyed. Because lead acid batteries can supply such high currents, it's important to assure that you use the right wire thickness / diameter.
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
