Lead-Acid batteries are quite picky when it comes to charging conditions and raised temperatures. Both too high and too low float-charge voltage will shorten the lifetime, through different chemical mechanisms, and the ideal charging voltage depends on the temperature (3mv/cell/°C) and the exact alloy of lead used in the electrodes.
naturally occurs during normal charging, but when a lead acid battery is overcharged, the electrolyte solution can overheat, causing hydrogen and oxygen gasses to form, increasing pressure inside the battery. Unsealed flooded lead acid batteries use venting technology to relieve the pressure and recirculate gas to the battery.
