    FAQs about Lead-acid batteries occasionally run low

    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 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.

    What happens when a lead acid battery is recharged?

    At the same time the more watery electrolyte at the top half accelerates plate corrosion with similar consequences. When a lead acid battery discharges, the sulfates in the electrolyte attach themselves to the plates. During recharge, the sulfates move back into the acid, but not completely.

    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 you keep a battery at a low charge?

    According to Battery University, keeping a battery operating at a low charge (below 80%) can lead to stratification, where the electrolyte “concentrates on the bottom, causing the upper half of the cell to be acid-poor.” This can affect the overall performance of the battery and eventually lead to failure.
