Lead-acid batteries are widely used in various applications due to their reliability and cost-effectiveness. However, their performance, particularly during discharge, can be significantly influenced by environmental factors, with temperature being one of the most critical.
Temperature has a profound impact on the electrochemical reactions within a lead-acid battery. At lower temperatures, the chemical reactions slow down, leading to reduced ion mobility and increased internal resistance. This results in a lower discharge capacity and voltage output. Conversely, higher temperatures can accelerate these reactions, potentially increasing the discharge capacity. However, excessively high temperatures can also lead to accelerated degradation of the battery components, such as the corrosion of the positive grid and the shedding of active material, which can ultimately reduce the battery’s lifespan.
Understanding the temperature effects on lead-acid battery discharge performance is crucial for optimizing their use in various environments. Proper thermal management and temperature compensation techniques can help mitigate these effects, ensuring consistent performance and prolonging battery life.
