6 Frequently Asked Questions about “Will lead-acid batteries go bad if they are not used frequently ”

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.

Are lead acid batteries really that bad?

In addition to all that wasted generator time, lead acid batteries suffer another efficiency issue – they waste as much as 15% of the energy put into them via inherent charging inefficiency. So if you provide 100 amps of power, you've only storing 85 amp hours.

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.

Are lead acid batteries maintenance free?

Flooded lead acid batteries must be periodically topped off with distilled water, which can be a cumbersome maintenance chore if your battery bays are difficult to get to. AGM and gel cells though are truly maintenance free.
