Can I still drive if the battery warning light comes on?

You should not drive if the battery warning light comes on. The reasons for the battery warning light are: 1. Internal damage to the alternator causing insufficient power generation; 2. Slippage of the alternator's pulley, obstructing the power source and preventing the alternator from working; 3. Faulty wiring in the alternator leading to insufficient power generation; 4. Battery discharge causing inability to store power. Solutions for the battery warning light include: 1. Check if the battery terminals are loose; 2. Inspect whether the alternator belt is loose or slipping; 3. Visit a 4S shop for inspection or repair. Battery maintenance methods include: 1. Turn off lights and audio before shutting down the engine; 2. Turn off the air conditioning before shutting down the engine; 3. Avoid long-term parking; 4. Clean regularly; 5. Conduct periodic battery checks; 6. Monitor the battery status indicator promptly.
I encountered this situation last time when I was taking my kids to school. Suddenly a red battery warning light popped up on the dashboard, and my heart skipped a beat. Honestly, it's best not to push your luck in this kind of situation - pull over immediately to check. A battery warning indicates there's an issue with the charging system, which could mean a broken alternator belt or a faulty voltage regulator. Once I stubbornly kept driving for ten more minutes, and the engine completely died at an intersection - air conditioning and power steering locked up, extremely dangerous. My advice: when the warning light comes on, immediately turn off power-hungry accessories like AC and stereo, turn on hazard lights, and head straight to a repair shop. Don't count on restarting after turning off the engine - speaking from experience, it likely won't start again!
Having repaired cars for twelve years, I always advise customers with battery warnings to stop immediately. That light doesn't mean the battery is bad—it means the alternator isn't charging. Think about it: the engine drives the alternator via a belt. If it's not charging, the car is running on reserves. The battery might last 30-40 km at most, depending on whether headlights or stereo are on. Once, we towed a Mercedes whose owner pushed until the battery died—steering assist failed, nearly causing a crash into guardrails. Worst are modern cars: when electronics lose power, transmissions can lock gears. Imagine total blackout on a nighttime highway—no hazards, nothing. Terrifying.
