How Long Will A Car Battery Run A Refrigerator

If youre using a Lead Acid battery you can only discharge to about 50 without causing damage and shortening battery life so with Lead Acid batteries youll get about half that run time or 12 to 25 hours.

How long will a car battery run a refrigerator. Running 8 hours is a total of 9792 amps. BatteryStuff Tech 17 watts 125 volts 136 amps. Answer 1 of 11.

You can make a ROUGH estimate based on the battery capacity voltage and the power rating of the appliance. Furthermore how long will a 12 volt battery run a refrigerator. If you discharge it.

A small fridge may consume 100W to keep running and if perhaps you do not open the door often it may consume 50 W. A 12 volt fridge freezer will run between 25 and 50 hours on a 12v 100 Ah amp hour LiFEP04 Lithium Iron Phosphate battery. If disconnected from the car a 12 - volt 50AH equivalent flooded lead-acid car battery and a properly sized inverter 1500 watts minimum can power a fridge for about 11 minutes until 50 drained and about 21 minutes until the battery is completely discharged.

Batteries and refrigerators come in different sizes and usage rates also depend on things like how long the door is opened and what the room temperature is. So the fridge can run for about 12 hours. If you were to end the day with a 7-8 hour drive and then stop for 8 hours the battery would keep the fridge running worst case.

I couldnt easily find how long the battery takes to recharge on DC but it says 7-8 hours from the wall so lets assume that for DC too. If disconnected from the car a 12-volt 50AH equivalent flooded lead-acid car battery and a properly sized inverter 1500 watts minimum can power a fridge for about 11 minutes until 50 drained and about 21 minutes until the battery is completely discharged. Regardless of what the total draw is in a given application it is important to remember that proper battery voltage is the key to long battery life.

A RV refrigerator or a residential refrigerator for Rv consuming around 150 watts while it is running would be drawing around 12 amps hour from a single 12 V battery. 832 Ah x 125 104 Ah. A small fridge might pull 100 W when runningOf course they run intermittently so maybe average 50 W if you dont open the door a lot.
