Buick Sportwagon Car Battery Replacement at your home or office.

How do mechanics replace the battery?

• 可能会安装临时电源，以避免电池电池电量时丢失无线电预设或存储数据的可能性。当电池已经完全死亡时，此步骤是不必要的。
• 车辆的负电缆从电池中卸下，然后是正电缆。电池扎以下系统松动，卸下了旧电池。
• 仔细检查电缆末端和布线，以确保清洁度和无腐蚀。在某些情况下，腐蚀可能是极端的，并且可能需要更换电缆或修复布线。
• The new battery is installed and the tie down system is reinstalled. Anti-corrosion compound is applied to the battery terminals. The positive terminal is reconnected followed by the negative terminal.
• Some vehicles, for example some models of BMW, VW, and Audi, may require PCM programming to input battery parameters. This step, performed using a specialized scan tool, is necessary to maximize battery life and prevent electrical system malfunctions.
• 启动汽车，并测量充电系统输出并与工厂OEM规范进行比较，以确保新电池能够正确充电。通常，充电输出在13.8至14.8伏的范围内，但确切的规格因品牌和模型而异。
