A 100-ah battery will run a fridge for about 20 hours. If you are using a 12-volt fridge, then you will need a minimum of 100 watts of power. But you should factor in some additional capacity for other devices that may be running simultaneously.

If your 100-ah battery has a discharge rate of 50%, you can run a refrigerator of 50 watts for about 20-25 hours. If you use a 120-volt fridge, you will need a minimum of 1200 watts of power.

**How to calculate the power of a refrigerator?**

Fridge Wattage x Hours Per Day = Watt-hours per day

Total Cost= Watt-hours per day x 365 x unit price

If you use 150 Watts for 24 hours a day for $0.10 per kWh, then your:

- Cost Per Hour: 0.0150
- Cost Per Day: 0.3600
- Cost Per Month: 10.95
- Cost Per Year: 131.41
- kWh Per Day: 3.60

**How many hours would a 100 Ah battery power a refrigerator?**

Power consumption of refrigerator: 100 watts

For a 100 Ah battery, the voltage will be 12V

How many hours would a 100 Ah battery power a refrigerator?

The voltage of a battery does not affect how long it can power a device. The only factor that determines how long a battery can power a device is its capacity, measured in amp-hours (Ah).

In this case, the battery has a capacity of 100 Ah, which means it can provide 100 amps of current for 1 hour.

If the refrigerator has a power consumption of 100 watts, then the battery can power it for approximately 1 hour.

This is because 100 watts / 100 amps = 1 watt/amp, and a 100 Ah battery provides 100 amps of current.

**How much electricity does a refrigerator typically consume?**

A refrigerator is one of the most energy-intensive appliances in your home.

Let you have a refrigerator of 250 watts. That means that over the course of a day, a fridge can use up to 1 kilowatt-hour (kWh) of energy.

A typical 250-watt refrigerator uses approximately 1 kilowatt-hour (kWh) of electricity per day. This translates to about 30 kWh per month and 360 kWh per year.

The actual amount of electricity used may vary depending on the age and efficiency of the refrigerator, as well as how often the door is opened.

If you’re looking to save money on your electric bill, you can do a few things to reduce your fridge’s power consumption.

A research showed that households with an old fridge used an average of 958 kilowatt-hours (kWh) of electricity per year. This is compared to the average usage of just 304 kWh for households with a new fridge.

The study also found that old fridges are more likely to be located in homes that are “energy poor” – meaning they spend a larger proportion of their income on energy bills.

If you’re considering upgrading your fridge, it could save you both money and energy. Newer models are much more efficient and can help reduce your carbon footprint.
