The performance of Lead-Acid Batteries is greatly affected by temperature.
In low temperature environments, the performance of Lead-Acid Batteries will decrease significantly. This is because low temperature will increase the viscosity of the electrolyte, slow down the ion diffusion rate, and increase the internal resistance. This weakens the battery's discharge capacity and reduces its output current, thus affecting the normal use of the device. For example, in the cold winter, cars powered by Lead-Acid Batteries may have difficulty starting, and the cruising range of electric bicycles will also be significantly shortened. In addition, low temperatures will reduce the battery's ability to accept charge, prolong charging time, and may not fully charge the battery.
On the contrary, Lead-Acid Batteries will also face some problems in high temperature environments. High temperatures will accelerate chemical reactions inside the battery, leading to increased corrosion of the plates and evaporation of the electrolyte. This will shorten the service life of the battery, and may also cause thermal runaway of the battery, increasing safety risks. Moreover, the battery's self-discharge rate accelerates in high temperature environments, and the battery's power will be lost faster even if it is not used.
Generally speaking, the optimal operating temperature range of Lead-Acid Batteries is usually between 20℃ and 25℃. Within this range, the performance of the battery is relatively stable and it can exhibit better charge and discharge efficiency and capacity.
For example, in some areas with higher temperatures, such as desert areas, if Lead-Acid Batteries do not have good heat dissipation measures, their service life may be significantly shortened. In cold northern regions, Lead-Acid Batteries stored outdoors in winter may not work properly due to low temperatures.
To mitigate the effect of temperature on the performance of Lead-Acid Batteries, some measures can be taken. In low temperature environments, the battery can be properly preheated before use or charging. In a high-temperature environment, ensure that the battery has good ventilation and heat dissipation conditions and avoid direct sunlight.
In short, temperature is an important factor affecting the performance of Lead-Acid Batteries. Understanding and mastering the performance characteristics of Lead-Acid Batteries in different temperature environments and taking corresponding measures for optimization and protection are of great significance to ensuring the normal operation of the battery and extending its service life.
