What Causes a Dead Battery in the Buick Envision?

[MacNaomi]

For a dead battery in the Buick Envision, it is recommended that the owner wait for assistance from a 4S dealership. Below are the reasons why the Buick Envision can only wait for professional help when the battery dies: 1. Because the Envision's battery is not a standard battery but a specialized AGM battery for start-stop systems, the charging method differs and cannot be charged by oneself. 2. Due to the frequent engine restarts required by the start-stop system, the battery must support frequent high-current discharges. Correspondingly, when the vehicle's charging system recharges the battery, the battery must also have strong charge acceptance performance and high capacity to meet the electrical demands of onboard electronics when the engine is off. Occasionally jump-starting the vehicle once is generally not a major issue. As long as the starting voltage is appropriate and the output current is sufficient, jump-starting is possible. However, there are specific operational standards and techniques involved; improper handling can easily damage the vehicle's computer.
