Over time, the lead plates inside the battery corrode, and the electrolyte solution can become diluted or contaminated, which can impede the battery’s ability to hold a charge effectively. Furthermore, frequent extreme temperatures—both hot and cold—can exacerbate these degradation processes.
The term “capacity” refers to the battery’s ability to store and deliver electrical energy. As a battery ages, its capacity diminishes. This decline occurs due to the accumulation of sulfation, a process where lead sulfate crystals form on the battery plates. This buildup reduces the surface area of the plates, thus limiting the battery’s effectiveness in charging and discharging energy.
Specific conditions can accelerate battery aging. For example, excessive heat can increase evaporation rates of the electrolyte and may also lead to accelerated corrosion of the battery components. Regular short trips do not allow the battery to fully recharge, which can also shorten its lifespan. Conversely, letting a battery sit unused can lead to self-discharge, leading to sulfation. For instance, a car that is frequently started but not driven long enough to recharge the battery may ultimately face premature failure.
