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.
All rechargeable batteries degrade over time. Lead acid and sealed lead acid batteries are no exception. The question is, what exactly happens that causes lead acid batteries to die? This article assumes you have an understanding of the internal structure and make up of lead acid batteries.
The following are some common causes and results of deterioration of a lead acid battery: Overcharging If a battery is charged in excess of what is required, the following harmful effects will occur: A gas is formed which will tend to scrub the active material from the plates.
If you are not familiar with lead acid batteries, see our article What is a lead acid battery. Ironically one of the most common reasons for battery failure is not an actual failure of the battery itself, it is people thinking the battery is dead.
The end of a lead acid battery's life may result from either loss of active material, lack of contact of active material with conducting parts, or failure of insulation i.e. separators. Overcharging is one common cause of these conditions.
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.
The click of a dead battery is never a welcome sound, especially if your battery should have plenty of life left. Check out these common causes of lead-acid battery failure and …
