Can a Car Battery Still Be Used When It Gets Hot?
1 Answers
If the battery gets slightly warm during charging, it can still be used. Here are the reasons for battery overheating: 1. Mismatch between battery and charger: Using an incompatible charger can cause the battery to heat up during charging. 2. Charger overheating issue: Most chargers lack pulse and negative pulse depolarization functions, often failing to maintain a constant voltage in the later stages of charging. This can cause the battery voltage to exceed permissible limits, leading to excessive gas release, water loss, and overheating. 3. Increased battery usage: As the battery undergoes more charge-discharge cycles, water molecules within the battery gradually deplete, causing heat generation during electrochemical reactions. Additionally, sulfate crystals form in the battery solution during charging and discharging, adhering to the plates and increasing internal resistance and heat. If the battery has an internal short circuit, it will also heat up.
