Why does the car not start even though the lights have power?

[LilaFitz]

If the car lights have power but the car won't start, it may be due to insufficient battery voltage. Insufficient voltage doesn't mean there's no power at all—horn and lights can still work, but there may not be enough power to start the engine. Below are some tips for car battery maintenance: 1. Drive frequently: Avoid leaving the car unused for long periods; regular driving helps keep the battery charged. 2. Pay attention to device usage: Turn off lights before shutting down the engine and minimize the use of in-car charging devices to prevent battery drain. 3. Regular inspections: Have the battery's charge capacity checked at a 4S shop every six months. 4. Regular cleaning: Wipe the battery periodically to prevent the buildup of corrosive acid powder.
