If lead acid batteries are cycled too deeply their plates can deform. Starter batteries are not meant to fall below 70% state of charge and deep cycle units can be at risk if they are regularly discharged to below 50%. In flooded lead acid batteries this can cause plates to touch each other and lead to an electrical short.
However, most chargers sold today are “smart” chargers and will shut off after the battery is fully charged. Myth: Any charger should work perfectly okay with any type of lead acid battery. Fact: There are many different technologies used in lead acid batteries.
Just because a lead acid battery can no longer power a specific device, does not mean that there is no energy left in the battery. A car battery that won't start the engine, still has the potential to provide plenty of fireworks should you short the terminals.
In both flooded lead acid and absorbent glass mat batteries the buckling can cause the active paste that is applied to the plates to shed off, reducing the ability of the plates to discharge and recharge. Acid stratification occurs in flooded lead acid batteries which are never fully recharged.
As routine maintenance, you should always check the battery electrolyte levels and ensure that the battery cells are always covered. Sealed and valve-regulated lead-acid batteries are designed in such a way that the gases released from the electrolysis of water in the electrolyte, recombine back to form water. 3. Thermal Runaway
