The battery has internal problems and/or the vehicle is overcharging and is probably giving off explosive fumes. Don't do anything to cause a spark anywhere near the battery and take it to a repair shop asap for diagnoses.
To test an overcharging alternator, first, use a multimeter to measure the voltage at the battery terminals with the engine running; it should typically read between 13.7 to 14.7 volts. If the voltage exceeds 14.7 volts, the alternator may be overcharging. Additionally, inspect the voltage regulator, as it controls the output of the alternator; a faulty regulator can cause overcharging. Finally, check for any loose connections or damaged wiring that could affect the alternator's performance.
