How to Prevent Car Battery from Dying in Winter?

[McMackenzie]

Methods to prevent car battery from dying in winter are as follows: 1. Turn off all electrical equipment after parking and check for any power leakage. The more electrical loads a car has, the higher the possibility of power leakage. To prevent the battery from draining too early, it is necessary to eliminate potential leakage hazards; after parking, turn off all electrical devices (dash cams, radios, audio systems, lights, navigation systems, etc.), and use a multimeter to check for any power leakage. 2. Manually charge the battery. Regularly charging the battery to reduce the state of discharge can extend its service life. 3. Clean the oxides on the battery terminals. Over time, white oxides may form on the battery terminals, affecting current flow or directly causing poor terminal contact, which worsens the already declining battery performance in winter and makes it difficult to start the car. If there are oxides, consider rinsing them with boiling water, wiping them clean with a cloth, and then applying grease.
