Should the car battery be replaced after 10 years of use?

Car batteries that have been used for ten years need to be replaced. Car batteries are consumables with a certain lifespan and require replacement after a period of use. Generally, car batteries can last between 2-5 years, depending on the type of battery, usage conditions, and maintenance. With proper maintenance and good driving habits, the lifespan of a car battery can be extended to 4-5 years. Here are the situations when a battery should be replaced: 1. Check the battery status through the inspection hole: Some batteries have an inspection hole, through which you can usually see three colors: green, yellow, and black, or green, black, and white. Typically, green indicates the battery is in good condition; yellow (or black) indicates insufficient battery capacity; and black (or white) means the battery is nearing the end of its life and needs replacement. 2. Judge by observing the battery's external condition: If there is noticeable bulging or deformation on both sides of the battery, or if there are white powdery substances around the terminals, it indicates a problem with the battery's performance, requiring repair or direct replacement.
I think a car battery that's been used for 10 years definitely needs replacement! As an ordinary driver, I've experienced the hassle of battery aging multiple times. Typically, a car battery lasts 3-5 years, with a maximum of 6-7 years. If it exceeds 10 years, the internal components deteriorate—starting the engine becomes sluggish, cold starts in winter are even harder, and you might suddenly break down on the road. Calling for a tow truck at that point is a real hassle, and repairs cost extra money. I advise you to quickly visit an auto repair shop to test the voltage—if it's below 12 volts, that's a sign of failure. Replacing a new battery doesn’t cost much, just a few hundred bucks, saving you from disrupting your travel plans. Pay more attention to this during routine maintenance to prevent issues in advance. Driving safely and reliably is the top priority—don’t take big risks to save small money.
From a cost-saving perspective, keeping a car battery for 10 years without replacement isn’t worth it. I’ve done the math: a new battery costs a few hundred yuan, but an old one might fail to start the engine, leaving you stranded with towing fees starting at several hundred. Worse yet, it could damage the alternator or starter, leading to repairs costing thousands. My neighbor went through this ordeal. An overused battery also strains the fuel system, posing serious risks during highway emergencies. Check for corrosion on the terminals; if lights flicker or dim during startup, replace it immediately. Annual voltage tests can catch early signs—don’t push your luck. A small investment now ensures greater peace of mind later.
