Does the Envision require decoding when replacing the battery?
2 Answers
The Envision requires the vehicle's computer to decode when replacing the battery; otherwise, even if a new battery is installed, it still won't charge. Precautions for battery replacement: Visually inspect the battery casing for cracks, corrosion, or signs of burning; use a voltmeter to measure the voltage between the casing and ground, ensuring it does not exceed 20V, as higher voltages pose an electric shock risk; after installing the new battery, use a Mercedes-Benz-specific computer to perform a battery test run. Car battery maintenance tips: Avoid parking the car in an open parking lot for extended periods. If long-term parking is necessary, remove the battery to prevent freezing damage; car batteries need regular charging, as prolonged disuse leads to gradual self-discharge and eventual failure. Therefore, start the car periodically to recharge the battery.
I've been driving a Buick Envision for several years. Last time when I changed the battery, a friend reminded me that new cars have battery management systems, and after power loss, the system might not remember the new battery data, causing the start-stop function to fail. I directly replaced the battery, and after starting, the fault light came on. Later, I had to visit a repair shop where they used a scanning tool to reset it before it worked normally. It's not strictly decoding, but it's better to perform a system reset to avoid minor issues, otherwise it might affect the driving experience. Usually, pay more attention to the manual's recommendations. Doing it yourself is fine, but don't skip that step. It's like how you need to reset your phone after a reboot - cars have become smarter too, so keep them updated.
