Corroded terminals decrease conductivity, leading to higher resistance and heat generation. According to the Battery Council International, corrosion can reduce battery efficiency and lifespan significantly (Battery Council International, 2021).
-
Overcharging: Overcharging can cause batteries to heat up excessively, resulting in terminal melting. This occurs when a battery receives more voltage than it can handle, leading to thermal runaway. Thermal runaway can make the battery swell and can even cause the terminals to melt. Reports indicate that proper voltage regulation is essential to avoid this issue (Cheng et al., 2020).
How Does Excessive Heat Lead to a Melted Positive Battery Terminal?
Excessive heat leads to a melted positive battery terminal due to a series of interconnected factors. First, when a battery generates excessive current, it creates heat. This heat increases the temperature of the battery terminal. Second, a high electrical resistance at the connection points can exacerbate heat production. Poor connections or corrosion can increase resistance, causing these points to heat up further. Third, if the battery experiences overcharging, it can heat up significantly, contributing to the melting of terminal materials. Finally, the materials used in battery terminals, like plastic and metal, have specific melting points. Once the temperature exceeds these limits due to sustained heat, the terminal material begins to melt. In summary, excessive current, high resistance, overcharging, and material properties all contribute to the melting of a positive battery terminal.
