6 FAQs about [Why can a lead-acid battery still be powered when it is dead ]

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 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 make sense?

Already covered by others but lead acid batteries make total sense in the right application and if you choose the right lead acid battery. The right kind can be deep cycled and can sustain 1000s of charge/discharge cycles. Almost every lead acid battery is made from mostly recycled materials.

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?
