What to Do When the Battery Gets Hot During Charging and the Light Doesn't Turn Green?

[LeArabella]

Solutions for when the battery gets hot during charging and the light doesn't turn green are as follows: 1. Damaged or mismatched charger: If the light doesn't turn green, the charger might be damaged. It is recommended to try another charger. However, ensure the charger matches the battery, e.g., a 42V battery requires a 42V charger. Using the wrong charger can damage the battery. Alternatively, use a multimeter to monitor the voltage in real-time. If the voltage reaches the battery's maximum but the light still doesn't change, this also indicates a charger issue. 2. Severely aged battery: If the electric vehicle has been used for a long time without a battery replacement, it might be due to severe electrolyte loss (as electrolyte depletes during charging). If electrolyte hasn't been replenished regularly, it will continue to decrease. If detected early, simply adding electrolyte can resolve the issue.
