Battery capacity calculator

Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.

How long will a 100Ah battery last?

A 100Ah battery can last anywhere from 120 hours (running a 10W appliance) to 36 minutes (running a 2,000W appliance).

How long will a 100Ah battery run an appliance that requires 400W?

A 100Ah 12 volt deep-cycle lead-acid battery can run a 400W continuous DC load for 1.5 hours with the recommended 50% Depth of Discharge.

How do you calculate power capacity?

Capacity – Watt-hour (Wh): Wh is calculated by multiplying the number of Amps with the battery voltage. For example, a 12V100 (a 12 volt battery with a capacity of 100Ah) has a capacity of 12 x 100 = 1200Wh.

What is battery capacity in kWh?

Battery capacity (kWh) This rating tells you how much electricity can be stored in the battery pack. It's a unit of energy just like calories and one kWh is equal to 3600 kilojoules (or 3.6 megajoules).

What can I run off a 200Ah battery?

A 200Ah lead-acid deep-cycle battery will run a 400W rated fridge for about 25 hours at a rate of 40 watts per hour.

What is the difference between 100Ah and 200Ah battery?

Amount of Power store (200Ah Vs 100Ah Vs 150Ah ) And the amount of power stored in a 12V, 150Ah battery will be equal to 12x150=1800Watt. Hence a 12V, 200Ah battery stores twice the power stored in a 100Ah battery and 1.3 times power more than a 150Ah battery.

What can a 150Ah battery run?

You can expect your 150 Ah battery to last for around 3 hours on 400 watts bulb load if it is fully charged. If the load or appliance wattage is reduced the backup will improve.

How long will a 100Ah battery run a washing machine?

A 100Ah 12 volt deep-cycle lead-acid battery can run a 400W continuous DC load for 1.5 hours with the recommended 50% Depth of Discharge.

What size solar panel do I need to charge a 100Ah battery?

Summary. You need a 3-6 watt solar panel to maintain a 100Ah lead acid battery.

What size inverter can I run off a 100Ah battery?

For example, a 100Ah lithium battery will power a 1000W inverter which is perfect for running laptops, televisions, blenders, power tools, and phone or camera chargers. A 1000W inverter is often the ideal size for most simple setups.

What is the capacity of a battery?

"Battery capacity" is a measure (typically in Amp-hr) of the charge stored by the battery, and is determined by the mass of active material contained in the battery. The battery capacity represents the maximum amount of energy that can be extracted from the battery under certain specified conditions.

How do you calculate how long a battery will last with Watts?

The Formula to Calculate Battery Run Time We use the formula: (10 x battery capacity in amp hours) divided by (appliance load in watts). This information appears on the lead acid battery label and in the small print on the appliance.

How do you calculate how long a battery will last?

We use this equation for battery drain time:

Battery Life (in hours) = Battery Capacity (in Ah) / Load Current (in A)
P (in W) = I (in A) * V (in V)
I (in A) = P (in W) / V (in V)
200 Ah Battery Life = 200 Ah / 6.67 A = 30 hours.
Amps Draw (in A) = 800W/ 240V = 3.33 A.
200 Ah Battery Life = 200 Ah / 3.33 A = 60 hours.

How many kWh is a 200Ah battery?

For example, let us convert 200 Ah at 12 V to kWh. (200 Ah x 12V) ÷ 1000 = 2.4 kWh or 2400 watts of energy can be consumed in one hour.

How many watts is a 200Ah battery?

Watt is the unit of power and the amount of power stored in a battery is equal to the multiple of its Voltage and Ampere- hours, hence 12 volts 200Ah battery is equal to 2400 watt (12x200), 24 volts 200 ah battery is equal to 4800 Watt (24 x 200) and a 48 volts 200 Ah battery is equal to 9600 Watt (48 x 200).

How many kWh is a 100Ah battery?

Power = Voltage x current Following this, the power stored in a 12V, 100Ah battery will be 12V x 100Ah = 1200 Watt-hour (Wh) or 1.2 kilowatt-hours (kWh).

How many solar panels do I need for a 200Ah battery?

You need around 520 watts of solar panels to charge a 12V 200Ah lead acid battery from 50% depth of discharge in 5 peak sun hours with a PWM charge controller.
