What causes lead acid battery cells to short out?
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.

Can a lead acid battery fail?
The battery may also fail as an open circuit (that is, there may be a gradual increase in the internal series resistance), and any batteries connected in series with this battery will also be affected. Freezing the battery, depending on the type of lead acid battery used, may also cause irreversible failure of the battery.

What happens when a lead acid battery is charged?
5.2.1 Voltage of lead acid battery upon charging. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide. As a by-product of this reaction, hydrogen is evolved.
What voltage does a lead-acid battery run?
The battery block that supplies current to these systems is usually sized according to the minimum required voltage of the external load and the ohmic voltage drop along the electrical line. Although currently rated at 2 V/e for sizing purposes, lead–acid batteries operate at a starting voltage of 2.1 V/e when fully charged.
What is the resting voltage of a 12V lead acid battery?
The resting voltage of a 12V lead acid battery refers to the voltage measured when the battery is not under load (i.e., not connected to any circuits or devices). After a period of rest, a fully charged battery should have a resting voltage around 12.6 to 12.8 volts.
What is a lead acid battery?
A lead acid battery consists of electrodes of lead oxide and lead are immersed in a solution of weak sulfuric acid. Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte.
