How long will an RV fridge run on battery?
Similarly, it is asked, how long will a 12 volt battery run a refrigerator?
If disconnected from the car, a 12-volt, 50AH equivalent, flooded lead-acid car battery and a properly sized inverter (1,500 watts minimum) can power a fridge for about 11 minutes until 50% drained, and about 21 minutes until the battery is completely discharged.
Furthermore, how long will a deep cycle battery run a fridge? A decent fridge around that size under 30 degrees ambient temperature shouldn't use more than around 30 - 40 amp hours a day. Normal deep cycle batteries have a cycle life of about 1500 times, when you only use 30% of their capacity.
Keeping this in view, how long will an RV residential fridge run on battery?
According to Gone with the Wynns, an average residential fridge will use about 130 amp-hours of battery in 11 hours. Keep in mind that most standard RV's come with four 6V batteries that only offer about 'useable' 200 amp-hours on 20 hour rating on full charge.
How long will a RV battery last?
Check the state of charge on a regular basis, and after the batteries have charged check the water levels. The bottom line is a little routine maintenance and recharging a discharged battery as soon as possible will extend the life of the battery. RV batteries can and should last 5 to7 years, rather than 1 to 2 years.
