Why does the battery get hot after adding repair fluid?
2 Answers
Because when current flows through the internal resistance of the battery, heat is generated. If you feel that it is getting hot, the possible reason is the existence of a cell short circuit. It is recommended to go to a repair shop for inspection and treatment. The following are specific introductions about battery maintenance: Avoid storage in a discharged state: A discharged state means that the battery is not charged in time after use. When the battery is discharged, sulfation is prone to occur. Lead sulfate crystals adhere to the plates, blocking the ion channels, resulting in insufficient charging and reduced battery capacity. Regular inspection: During use, if the battery's ability to store electricity decreases, it is likely that at least one battery in the battery pack has problems such as broken grids, softened plates, or shedding of active material from the plates, which are short-circuit phenomena. At this time, it is necessary to go to a professional battery repair institution for inspection, repair, or grouping in time. Avoid high-current discharge: When starting the car, do not start it continuously, and try to avoid instantaneous high-current discharge. High-current discharge can easily lead to lead sulfate crystallization, thereby damaging the physical properties of the battery plates.
I've experienced a similar situation before and found that the battery became hot after adding repair fluid, mostly due to improper addition of the repair fluid or internal battery issues. Repair fluid is typically used to replenish electrolyte or restore aging batteries, but if you add too much too quickly, or fail to shake it evenly after adding, it may cause uneven distribution of the liquid, leading to concentrated current and localized overheating. Another common reason is that the battery already has an internal short circuit or cracks, and the repair fluid triggers abnormal chemical reactions upon penetration, generating excessive heat. Additionally, if the vehicle's charging system is faulty, such as an overcharging alternator, adding repair fluid can exacerbate this issue, causing the battery to heat up more severely. I recommend stopping the vehicle immediately, checking if the battery surface temperature is abnormally high, and ensuring proper ventilation. It's best to disconnect the power and contact a professional repair shop to test the battery's health to avoid safety risks like fire or explosion. During regular maintenance, add repair fluid in small amounts multiple times, follow the instructions carefully, and avoid rushing to drive afterward.
