If you want to convert between amp-hours and watt-hours or find the C-rate of a battery, give this battery capacity calculator a try. It is a handy tool that helps you understand how much energy is stored in the battery that your smartphone or a drone runs on.
How to size your storage battery pack : calculation of Capacity, C-rating (or C-rate), ampere, and runtime for battery bank or storage system (lithium, Alkaline, LiPo, Li-ION, Nimh or Lead batteries.
This battery life calculator estimates how long a battery will last, based on nominal battery capacity and the average current that a load is drawing from it. Battery capacity is typically measured in Amp-hours (Ah) or milliamp-hours (mAh), although Watt-hours (Wh) is occasionally used.
Find out the remaining capacity of your battery using Omni's battery size calculator.
The battery size calculator calculates the battery size in ampere-hour (Ah). See Also. Cable size calculator AS/NZS 3008. Maximum demand calculator AS/NZS 3000. Arc flash calculator IEEE 1584. Parameters. Load (ampere or watt): Specify the load value, and select the load unit. For example, 100 Watt.
The first one tells you what capacity your battery has depending on the voltage and watt-hours, while the second one estimates how long your battery will run with a specific capacity and discharge current. Check the battery capacity calculator to find your battery's watt-hours and run time.
Here's a useful battery pack calculator for calculating the parameters of battery packs, including lithium-ion batteries. Use it to know the voltage, capacity, energy, and maximum discharge current of your battery packs, whether series- or parallel-connected.
This free online battery energy and run time calculator calculates the theoretical capacity, charge, stored energy and runtime of a single battery or several batteries connected in series or parallel.
To calculate battery capacity in kilowatt-hours (kWh), use the formula: Capacity in kWh = Battery Voltage (V) × Battery Capacity (Ah) ÷ 1000. For example, a 12V battery with 100Ah capacity has 1.2 kWh (12 × 100 ÷ 1000). Lithium Battery Watt-Hour Calculator. To find watt-hours (Wh) for a lithium battery, multiply the battery’s voltage (V ...
This battery calculator helps you to estimate the runtime for a device based on the battery capacity, voltage, device power consumption, and system efficiency. How to Use: Enter the battery capacity in milliamp-hours (mAh).
