High Temperature: High temperature in a lead-acid battery occurs when the internal chemical reactions accelerate beyond normal. This overheating can lead to thermal runaway, where the heat produced exceeds the ability of the battery to dissipate it. A typical lead-acid battery operates at about 25°C (77°F).
Consider using insulation wraps or blankets specifically designed for battery temperature management. 4. Monitor temperature: Utilize temperature monitoring devices to keep track of battery temperature levels. If the temperature exceeds the recommended range, take necessary steps to cool down the battery or adjust its operating conditions.

For instance, the self-discharge rate of lead–acid batteries is affected by factors such as temperature and battery age. High temperatures accelerate the self-discharge process.
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as “thermal runaway.”
Similar with other types of batteries, high temperature will degrade cycle lifespan and discharge efficiency of lead-acid batteries, and may even cause fire or explosion issues under extreme circumstances.
Reduced Capacity: Cold temperatures can cause lead acid batteries to experience a decrease in their capacity. This means that the battery may not be able to hold as much charge as it would in optimal conditions. As a result, the battery’s runtime may be significantly reduced. 2.
