How Long Will Camper Fridge Run On Battery

A fridge drawing 30 amps on a 50 duty cycle will use 120 Ah in an 8 hour period.

How long will camper fridge run on battery. A three-way absorption refrigerator can run only for three hours. A very small user of power is a 12 watt LED light running on a 12 volt power source will use 12W 12V 01 amps. In our example it was a weekend trip so its two days.

First of all residential fridges operate way differently compared to RV fridgesFor one they are only powered by AC power and using an inverter the DC from a battery can be converted into AC and then power the refrigerator. If your battery is lithium and the fridge draws 25 amps runtime will be even longer. Lithium ion batteries may last for as many as 5000 charge cycles whereas deep-cycle batteries may only last for 400 or 500.

30 x 5 x 8. On average residential fridges tend to run for up to 12 hours on battery. A residential RV fridge will last for about 12 hours on batteries.

This time is less for a long road trip. I will test two 12 volt Deka deep cycle RV batteries to see just how long they can power your RV. You can also use an inverter along with the batteries to keep the fridge operating for a longer period of time.

That battery can receive a maintenance charge from the 12 volt circuit on a 7-Way trailer connector but the fridge would draw power faster than the 12 volt circuit can charge. Battery capacity is measured in Ah amps x hours. That depends entirely on the battery the 12 volt Everchill Refrigerator for RVs 324-000119 is being powered by.

An absorption fridge will run on batteries only for about 3 hours but if using propane too it will last for weeks. 208 watt-hours x 10080 26 Ah. 26 Ah x 2 52 Ah.
