Lead acid battery
A lead/acid battery contains sulphuric acid which combines to the plates when discharged. After time, this lead suphate becomes stabilised and is more difficult to dissociate into lead and sulphuric acid so capacity is lost. I do not think it matters how the battery is discharged. Keep the battery charged to reduce this effect to a minimum.
