Should I replace the car battery at a 4S shop or elsewhere?

[Bentley]

Both options are acceptable, but 4S shops are more expensive, so it's recommended to replace it at a repair shop. Here is a detailed introduction about car batteries: 1. Overview: The battery is an essential part of a car, which 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 strips, and terminals. 3. Advantages: Compared with traditional batteries, modern batteries have advantages such as not requiring any liquid addition, easy terminal connection, and long power storage time. Since the battery uses a lead-calcium alloy grid frame, it produces less water decomposition during charging, has lower water evaporation, and releases minimal sulfuric acid gas due to its sealed case design.
