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 lose water?
The production and escape of hydrogen and oxygen gas from a battery cause water loss and water must be regularly replaced in lead acid batteries. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem. If the system is in a remote location, checking water loss can add to costs.
