A good lead-acid car battery can provide about 1,260 Watt-hours of power. This energy can run a standard refrigerator for one to three hours, depending on its energy consumption. Make sure the battery is fully charged for the best results. Always check your refrigerator’s wattage for accurate runtime calculations.
However, several factors can affect this duration. These include the refrigerator’s efficiency, the ambient temperature, and the battery’s overall health. Additionally, using a power inverter can facilitate the conversion of the battery’s DC power to AC power needed for most refrigerators.
Choosing the right 12V solutions, such as portable solar panels or dedicated inverter batteries, can enhance this setup. These options can recharge the battery while simultaneously powering the refrigerator during extended trips or power outages.
In the next section, we will explore the best practices for connecting your car battery to a refrigerator and the alternatives available for longer-lasting solutions.
