What size battery do I need to run a fridge?
The average fridge consumes 40 watts of electricity per hour which means 960 watt-hours of battery capacity would be needed to run a fridge for 24 hours. 960 watt-hours equates to 80Ah, so a 160Ah deep-cycle lead-acid battery discharged to 50% will be required.
Do deep cycle batteries require a special charger?
Due to the increased demand placed on deep cycle batteries, there is a special conditioning process that helps keep your battery healthy while it is plugged in to the charger. Your best bet is to look for a smart charger that includes testing lights so that you can monitor your battery’s condition during charging.
How long will a deep-cycle battery run a fridge?
A 100Ah lead-acid deep-cycle battery will run a fridge using 630kWh/year for 13.3 hours. 80% discharge is assumed, but at the recommended DoD of 50% the same 100Ah battery will run the fridge for 8.3 hours. A lithium iron phosphate 100Ah battery will run the fridge for 15.8 hours at 95% discharge.
How many 12V batteries are needed to power a fridge?
Minimum Power Needed for a Residential Fridge The minimum power for running solely the residential fridge for 24 hours is six AGM batteries totaling 600 amp hours (300 ah usable).
How long will a battery run a 12V fridge?
How long will a 12 volt battery run a 12V refrigerator. If you’re using a Lead Acid battery, you can only discharge to about 50% without causing damage and shortening battery life, so with Lead Acid batteries, you’ll get about half that run time, or 12 to 25 hours.
What to consider when choosing a deep cycle battery?
The key factor to consider when selecting deep cycle batteries for your trolling motor is their reserve capacity – a larger number here means that your batteries will provide more power for more hours on the water.

How big of solar panel do I need to charge a 12V battery?
Charging your battery at 12 volts and 20 amps will take five hours to charge a 100 amp hour battery. By multiplying 20 amps by 12 volts, 240 watts is how big of a panel you would need, so we’d recommend using a 300w solar panel or 3 100 watt solar panels.
