Should I replace the car battery at a 4S shop or an external repair shop?

Both options are acceptable, but 4S shops tend to be more expensive, so it's recommended to go to a repair shop for replacement. Below is a detailed introduction about car batteries: 1. Overview: The battery is an essential part of a car and can be divided into traditional lead-acid batteries and maintenance-free batteries. 2. Structure: The structure of a car lead-acid battery mainly consists of positive (negative) plates, separators, electrolyte, case, connecting straps, and terminal posts. 3. Advantages: Compared to traditional batteries, modern batteries have advantages such as not requiring any liquid addition, easy connection to terminal posts, and long power storage time. Since lead-calcium alloy is used for the grid frame in these batteries, water decomposition during charging is minimal, water evaporation is low, and the sealed structure of the case also reduces the release of sulfuric acid gas.
I usually choose to replace the battery outside because it's much cheaper. Dealerships charge over a thousand, while chain stores outside only cost five or six hundred, saving half the money. You can pick the battery brand yourself, like Varta or Camel, but make sure to choose the right specifications to avoid current mismatch. The installation process is quick; just find a reliable quick repair shop, and it's done in 20 minutes. Although dealerships offer original batteries, I don't think it's necessary to spend extra money, especially for older cars with high mileage. Regularly check the battery condition during maintenance to avoid sudden failure on the road.
I still recommend replacing the battery at a 4S store. Although it's more expensive, the original battery is more reliable with better compatibility, avoiding any issues. The installation process is professional, and the technicians understand the vehicle's electrical system, so nothing gets damaged. The key point is the long-term warranty, usually offering free replacement within a year, saving you from future hassles. Small shops outside may offer tempting prices, but the batteries could be refurbished or poorly matched, easily leading to ignition failures. If your vehicle is still under warranty, prioritize the 4S store to avoid losing coverage. Check your battery's lifespan yourself and don't wait until it completely dies before taking action.
