6 FAQs about [Lead-acid battery loses half of its power]

What happens when a lead acid battery is charged?

When a sealed lead acid battery is charged, electrical energy is converted into chemical energy, which is stored in the battery. The lead plates and lead oxide plates react with the electrolyte to form lead sulfate and water. When the battery is discharged, the lead sulfate and water react to form lead, lead oxide, and sulfuric acid.

What causes a lead acid battery to fail?

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.

What happens if a lead acid battery is flooded?

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.

Do lead acid batteries degrade over time?

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.

What happens if you buckle a lead acid battery?

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.

What happens if a lead acid battery doesn't start a car?

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.
