This contribution discusses the parameters affecting the thermal state of the lead-acid battery. Lead-acid batteries are among the most widely used energy storage solutions across various industries, including automotive, renewable energy, and backup power systems. However, like most battery technologies, their performance can degrade significantly under certain environmental conditions. It was found by calculations and measurements that there is a cooling component in the lead-acid battery system which is caused by the endothermic discharge reactions and electrolysis of water during. One of the most critical processes in the production of lead-acid batteries is the electrochemical formation of the plates. In the case of VRLA (valve-regulated lead-acid) batteries with glass mat separators, this process is carried out post-assembly, after the plates are sealed in the battery. Battery performance is highly sensitive to temperature extremes. Cold weather, thermal cycling, and fluctuating charge/discharge conditions can significantly impact efficiency, reduce amp-hour capacity, shorten lifespan, and hinder rechargeability. However, a fully charged lead-acid battery can function down to -50 degrees Celsius. We offer products for managing issues like thermal conductivity, thermal cycling, thermal shock, and extreme temperatures.
