What are the methods to extend battery life?

Methods to extend battery life include: 1. Avoid overusing the battery; 2. Regularly clean the positive and negative terminals of the battery; 3. Periodically check the vent holes on the non-maintenance-free battery cover to prevent blockage; 4. Avoid low battery water levels. Precautions for car battery discharge are: 1. Turn off all electrical equipment before parking; 2. Turn off the car lights after turning off the engine; 3. Avoid frequent short-distance driving; 4. Do not let the battery run out of power; 5. Regularly check the battery voltage. The functions of a car battery are: 1. Provide current to the starter when starting the engine; 2. Assist the generator in supplying power to electrical equipment when the generator is overloaded; 3. Supply power to electrical equipment when the engine is idling.
I pay close attention to this because battery replacement can be quite expensive. The key to prolonging battery life is avoiding deep discharge. It's best to ensure the engine runs for at least 15 minutes each time you use the car. Short trips of just 3-5 kilometers before turning off the engine are particularly harmful to the battery. Remember to turn off all electrical appliances after shutting down the engine, especially the air conditioning and headlights. I once saw a friend forget to turn off the reading light, resulting in the car not starting the next day. If the car won't be used for an extended period, it's recommended to start it every two weeks and drive for about half an hour to recharge the battery. Also, try to avoid parking in direct sunlight as high temperatures can cause the electrolyte to evaporate, and freezing in winter can be even more troublesome. Actually, buying a battery voltage tester is quite practical for regular voltage checks to stay informed.
When it comes to extending battery life, I usually focus on three aspects. First is parking habits - even on hot summer days, avoid idling with the AC on for long periods while waiting. When the engine isn't running, the AC compressor relies solely on the battery, which drains it significantly. Second, during regular maintenance, have the technician clean the battery terminals. The buildup of white corrosion can cause poor contact - I once had starting difficulties due to corrosion. Finally, be cautious when installing additional equipment. Devices like dash cams are best connected to the ACC circuit rather than directly to constant power. If I'm away on business for over two weeks, I disconnect the negative battery terminal before leaving, and reconnecting it upon return generally doesn't affect usage.
