Why inverter battery gets hot?
- Overcharging: If the battery is charged at a higher voltage or current than specified, it can cause excessive gassing, which leads to the generation of heat within the battery. Overcharging can also cause the electrolyte to evaporate, resulting in increased resistance and even more heat generation.
- High discharge rates: When a lead-acid battery is subjected to high discharge rates or heavy loads, it generates heat due to the internal resistance of the battery. This can lead to increased battery temperature, especially if the battery is not designed to handle such high loads.
- Poor ventilation: Insufficient ventilation around the battery can impede heat dissipation, causing the battery to heat up. Proper airflow around the battery is essential to maintain a safe operating temperature.
- High ambient temperature: Operating the battery in a high-temperature environment can cause the battery’s temperature to rise. High ambient temperatures can also increase the rate of chemical reactions within the battery, further contributing to heat generation.
- Internal short circuit: An internal short circuit in the battery can cause excessive current flow and generate heat. This can result from manufacturing defects, damage to the battery plates, or the formation of dendrites due to overcharging or deep discharging.
- Age and degradation: As a lead-acid battery ages, its internal resistance may increase due to factors such as sulfation, grid corrosion, and plate degradation. This increased resistance can lead to higher heat generation during charging and discharging.
To prevent a lead-acid tall tubular inverter battery from overheating, it’s essential to follow the manufacturer’s guidelines for charging and discharging, ensure proper ventilation, and regularly inspect and maintain the battery. Overheating can cause performance degradation, shorten the battery’s lifespan, and even pose safety risks, such as thermal runaway and explosion.
