What are the effects of a depleted battery on a car?

The effects of a depleted battery on a car include: 1. Unstable engine idling; 2. Reduced actual fuel injection by the engine; 3. Weakened ignition energy; 4. Inability to deactivate the anti-theft alarm; 5. Locking of the audio system; 6. Abnormal operation of related systems. Precautions for battery maintenance: 1. Avoid parking the car in an open parking lot for extended periods. If long-term parking is necessary, remove the battery to prevent freezing damage; 2. In winter, car engines are harder to start. Each attempt to start the engine should not exceed 5 seconds, with intervals of at least 15 seconds between attempts. Avoid multiple uninterrupted starts, as this can cause the battery to burn out due to excessive discharge.
I drive quite frequently, and battery drain is really a headache. Last time when I returned from a business trip, my car wouldn't start and I had to call for roadside assistance. The main impacts are the engine failing to ignite, dashboard lights becoming extremely dim, and the door remote control malfunctioning, leaving me no choice but to manually unlock the door with the key. In more severe cases, onboard smart devices like the navigation system and power windows can also malfunction. The most annoying part is when the car won't start in the garage, forcing me to find someone to jump-start it. Additionally, frequent battery drain can shorten the battery's lifespan—instead of lasting three years, it might need replacement in just two. So now, I regularly check the battery terminals for oxidation. If the car won't be driven for an extended period, I disconnect the negative terminal to prevent discharge, or I keep an emergency jump starter in the trunk just in case.
