When Should a Car Battery Be Replaced Due to Low Lifespan?
2 Answers
The designed lifespan of a car battery is 27 months. Generally, family cars are more economical, and the battery in a new car can often last 3-4 years. However, after the first replacement, it is usually necessary to replace it again in about 2 years. Battery maintenance methods: Frequent charging: Car batteries should be charged regularly. If a battery is left unused for a long time, it will gradually discharge on its own until it becomes unusable. Therefore, the car should be started periodically to charge the battery. Regular cleaning: Clean the battery terminals periodically and apply specialized grease to protect the wiring harness. Regularly inspect the battery's components and connecting circuits. Avoid using electrical devices after turning off the engine: Using car electrical devices after the engine is turned off is prohibited. Running the battery alone without the engine generating power can cause damage to it.
I've been driving for several years and found that battery life is a major issue. When the voltage drops below 12.4 volts, it's time for a replacement—this is what professional equipment indicates. Like the last time my car wouldn't start, the mechanic measured it and immediately said the battery was done. Typically, a battery lasts 3 to 5 years, but if you frequently take short trips or have difficulty starting in cold weather, its lifespan may be even shorter. If not replaced in time, the engine may repeatedly fail to start, leading to high towing costs and unnecessary delays. I suggest keeping an eye on the dashboard regularly—dimming lights or delayed starts are warning signs. Getting the voltage checked periodically at a shop is simple and reassuring. This way, you can avoid the hassle of breaking down on the road.
