Why is it critical to monitor the operating temperature of lead-acid batteries?

Monitoring the operating temperature of lead-acid batteries is essential for ensuring maximum battery life expectancy. Lead-acid batteries are sensitive to temperature fluctuations, as their performance and longevity are significantly affected by operating conditions. High temperatures can accelerate chemical reactions within the battery, leading to increased corrosion of battery components and the degradation of the active material.

Conversely, excessively low temperatures can lead to reduced efficiency, increased internal resistance, and diminished capacity. By keeping the battery within the recommended temperature range, it can function optimally, which helps to prolong its lifespan and maintain its performance over time. This monitoring plays a vital role in battery maintenance and helps prevent premature failure, ensuring that the batteries provide reliable service throughout their intended lifecycle.
