What to Do When the Buick Envision Runs Out of Battery?
2 Answers
If your Buick Envision runs out of battery, it is recommended to wait for assistance from a 4S dealership. This is because the Envision's battery is not a standard one; it is a specialized AGM battery for start-stop systems, which requires a different charging method and cannot be charged on your own. Below is some relevant information: 1. Due to the frequent engine restarts by the start-stop system, the battery needs to support frequent high-current discharges. Correspondingly, when the vehicle's charger charges the battery, the battery must also have strong charging acceptance performance, as well as high capacity to meet the electrical needs of the vehicle's appliances when the engine is off. 2. Occasionally jump-starting the battery once is generally not a big issue. As long as the starting voltage is appropriate and the output current is sufficient, jump-starting is possible. However, there are operational norms and techniques involved, and improper operation can easily damage the computer system.
Last month, my Enclave also broke down, and I learned a lot when calling for rescue. Open the trunk and lift the mat—the battery is hidden in the spare tire well. Jump-starting must use thick cables. First, connect the positive terminal of the rescue vehicle, then clamp the positive terminal post of my car's battery. The negative cable should first clamp the rescue vehicle's negative terminal, and the other end must clamp a metal frame on my car (just find a screw). After starting the car, don’t rush to turn it off—rev the engine for at least 20 minutes to recharge the battery. A reminder: The 4S shop said this car's battery management system is quite sensitive. Getting the jump-start sequence wrong might fry the modules. If unsure, it's better to spend money on professional rescue—safety first.
