If we want to calculate how much energy – in other words, how many watt-hours – is stored in a battery, we need information about the electric charge in the battery. This value is commonly expressed in amp-hours – amps (units of electric current) multiplied by hours (units of time) – see the hours calculator.
If you want enough power for 3 days, you'd need 30 x 3 = 90 kWh. As discussed in the post above, the power in batteries are rated at a standard temperature, the colder it is the less power they have. So, with batteries expected to be at 40 to supply 10 kWh, with this data you'd multiply by 1.3 to see you would need 13 kWh of batteries.
This we can do using the following steps: Determine the kWh requirements of the device. Divide the battery kWh with the device kWh. Using the kWh = Ah X V / 1000 equation, we can calculate the total battery capacity. Here we have to pay attention to something called the battery discharge curve.
This rating means that the battery is able to provide a total of 10 Amperes of electrical current hours. This battery should be able to supply a 1 amp device with 10 hours of juice, or a 10 amp device with 1 hour of juice. What about our 2 amp lightbulb? 10 Ah / 2 A = 5 hours of power.
Discharging from a battery has inefficiencies, lead around .88 and lithium .96 to .98. So, if you're using Lithium it's 1.2/.96=1.25 kW/hr With that number we can see the power consumed per day is 24 x 1.25 = 30 kWh. If you want enough power for 3 days, you'd need 30 x 3 = 90 kWh.
ampere-hour is a more commonly used unit of calculating battery capacity. To maintain uniformity across all manufacturers, battery capacity mentioned by the manufacturers is the rated battery capacity. Essentially, the capacity tells how many amperes of electricity can be generated by the battery over a period of 20 hours.
