Why won't the battery start the engine?

It may be due to insufficient battery voltage. Here are the detection methods: 1. Low car battery voltage; Specific detection method: Use a multimeter voltage range to test the battery voltage. If it's below 10V, replacement is recommended. If it's around 11V, it can barely be used, but prepare for replacement. Above 12V is acceptable for use; 2. Check if it's caused by carbon deposits; If the vehicle has run about 20,000 KM, focus on inspecting and cleaning the throttle valve; 3. Inspect, test, and replace the spark plugs; 4. Confirm the quality of the gasoline used; 5. Inspect the ignition switch; 6. Test and inspect components related to the starting and fuel supply system, such as the starter, fuel pump, and sensors.
I've been driving this car for five years and have encountered the battery failing to start several times, mostly due to battery aging. The lifespan of a battery is generally 2-5 years, and after that, the power gradually declines. One winter morning when I was heading to work, the car wouldn't start, and after a lot of trouble, I realized I had left the audio system on the night before, which drained the battery. It's advisable to use simple tools to test the battery voltage; if it's below 12 volts, it might be a sign of low power, and you can temporarily remedy it with jumper cables or a charging device. But more importantly, it's about daily habits: check that all devices are turned off when parking, don't let the car sit idle for too long; if the battery is over 3 years old, it's better to replace it outright to avoid safety risks at critical moments. Regular maintenance saves both worry and hassle.
