[McVera]

It is not mandatory to replace the car battery at a 4S store. The specific details are as follows: 1. Replacement location: You can replace the battery yourself or have it replaced at an auto repair shop. Batteries generally need replacement every 2-3 years. 2. Service life: The warranty period for a new car is usually three years or over 100,000 kilometers, while the lifespan of a car battery is approximately 3 years. Information about car batteries is as follows: 1. Car battery: Also known as a storage battery, it is a type of battery that works by converting chemical energy into electrical energy. 2. Classification: Batteries are divided into conventional batteries, dry-charged batteries, and maintenance-free batteries. The commonly referred-to car battery is a lead-acid battery, with a normal service life ranging from 1 to 8 years.

You don't necessarily have to go to a 4S shop to replace your car battery. I've done it myself several times, and it's quite simple. Roadside repair shops or small auto parts stores are also good options, with prices significantly lower—4S shops usually charge around 400-500 RMB, while outside shops may only cost a little over 200 RMB. The key is to find a reputable shop or learn some basics before doing it yourself: for example, choose a battery of the right size, match the vehicle's voltage (usually 12V), and avoid buying cheap, low-quality products. When operating, first turn off the engine, wear gloves to prevent electric shock, and carefully connect the positive and negative terminals to avoid short circuits. Once, I bought a battery online and replaced it myself, finishing in ten minutes and saving both time and money. However, for beginners, it's still recommended to seek help from a professional technician, especially if the vehicle is under warranty, as 4S shops can ensure the use of original parts that won't affect the warranty. In short, consider your budget and convenience, and don't be fooled by 4S shops.

While not mandatory, I believe replacing the battery at a 4S dealership has advantages, especially for safety-conscious owners. Their technicians receive professional training to ensure precise installation of OEM batteries, preventing incorrect connections that could cause electrical system failures. As the power core, mishandling the battery may lead to short circuits, blown fuses, or even circuit board damage. During my last 4S visit, I paid more but had peace of mind; conversely, a friend opted for a roadside stall and ended up with poor contact in the new battery causing flickering headlights, requiring rework. DIY alternatives demand knowledge: learning basic automotive circuitry, preparing tools like wrenches, and ensuring vehicle power-off during operation. Though cost-effective, the risks make me favor professional services. Don’t overlook battery type differences—AGM batteries suit premium vehicles while conventional lead-acid types are more common.

You don't have to go to a 4S store to replace the battery. I find it more convenient to go directly to a repair shop. Time is money—4S stores require appointments and waiting in line, while outside shops can get it done within half an hour. Last time I went to a small shop, the technician quickly replaced the old battery after checking its deterioration, charged reasonably, and tested the voltage stability. Battery life usually lasts two to three years before needing replacement, and choosing the right brand like VARTA or Fengfan ensures better durability. You can replace it yourself, but be careful: wear gloves to prevent electric shock and make sure the engine is off before operating. Don't risk big problems to save small money—finding a reliable place is more reassuring.
