6 Frequently Asked Questions about “Why can t lead-acid batteries be over-discharged ”

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.

What happens if a lead acid battery is overcharged?

Charging a lead acid battery at high temperatures can cause serious damage to the battery and even lead to explosions. When a battery is overcharged, it may experience: Reduced Battery Life: Exaggerated use increases internal resistance, reducing the number of cycles performed.

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.

Why are so many lead acid batteries'murdered'?

So many lead acid batteries are 'murdered' because they are left connected (accidentally) to a power 'drain'. No matter the size, lead acid batteries are relatively slow to charge. It may take around 8 - 12 hours to fully charge a battery from fully depleted. It's not possible to just dump a lot of current into them and charge them quickly.

Should a lead acid battery be fused?

Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.

Should lead acid batteries be discharged only by 50%?

“Lead acid batteries should be discharged only by 50% to increase its life” – is an oft used phrase. This means that we should cycle them in the 100% to 50% window as shown below in the Typical state of charge window parameter. So it follows that the usable capacity of a lead acid battery is only 50% of the rated capacity.
