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.
Our area of expertise lies in industrial applications such as forklift truck lead acid batteries and we specialize in how to maximize the performance of the batteries to match and even reach beyond the life expectancy of the trucks themselves. In these applications the average guaranteed lifespan of a basic lead acid battery is around 1,500 cycles.
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.
Lead-acid batteries, widely used across industries for energy storage, face several common issues that can undermine their efficiency and shorten their lifespan. Among the most critical problems are corrosion, shedding of active materials, and internal shorts.
