As a veteran driver with twenty years of experience, I have personally encountered the issue of a broken battery cell. If there is an internal broken cell in the battery, it essentially means the battery is done for, as the damage to a single cell causes unstable voltage, difficulty starting the car, and even the engine making a clunking sound. On the surface, it might still manage to start a few times, but with dim lights and weak air conditioning. Prolonged use will force the alternator to overcompensate, risking damage to other components. Don't gamble with luck—a battery with a broken cell is like a ticking time bomb that could leave you stranded anytime. My most practical advice is to get it checked at a reputable repair shop immediately. Once confirmed, replace the battery right away. Always keep an eye on your battery's condition to avoid such troubles.
