How Do You Determine the Ideal Battery Capacity for a 12V Fridge?

To determine the ideal battery capacity for a 12V fridge, consider the fridge’s power consumption, the desired operating time, and the depth of discharge of the battery.

• Power consumption: Identify the fridge’s wattage rating. Most 12V fridges specify their power draw in watts. For example, a fridge consuming 50 watts will use 50 watts per hour.
• Desired operating time: Decide how many hours you want the fridge to run without recharging the battery. For instance, if you aim for 12 hours of operation, multiply the fridge’s hourly consumption by the number of hours. Using the earlier example, 50 watts x 12 hours = 600 watt-hours (Wh).
• Depth of discharge: Choose a battery type and understand its depth of discharge (DoD). Lead-acid batteries typically have a recommended DoD of 50%, while lithium-ion batteries can safely discharge up to 80-90%. For a lead-acid battery, you would need a capacity of at least 1200 Wh to provide 600 Wh of usable energy (600 Wh / 0.5 DoD). For a lithium-ion battery, a 600 Wh capacity may suffice (600 Wh / 0.9 DoD).

By considering these factors, you can accurately determine the ideal battery capacity needed to operate a 12V fridge efficiently.
