Example 1: Must calculate the watt-hour capacity of a car battery having a voltage of 12 volts and capacity of 60Ah: View example: Example 2: Must calculate the ampere-hours of a battery to have 100 watt-hour capacity at 7.2 volts: View example: Example 3: Must calculate the voltage of a battery having 80mAh and 288mWh: View example The key is to use the watts you know to calculate the amps at the battery voltage . If the battery was a perfect power source and behaved linearly, charge and discharge times could be calculated according to in-and-out flowing currents, also known as coulombic efficiency.What is put in should be available as output in the same amount; a 1-hour charge at 5A â¦ For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. The battery size calculator derates the battery linearly based in this characteristic. A clickable product link will generate in the calculator based on the model/configuration you select. Giving the necessary data we will deduct that each cell needs 247W. The rating of the battery reduces by approximately 62% if it is discharged in 1 hour. 44.4kw (previously calculated) will be divided by the number of batteries we have available, and the result will lead to 1481 watts per battery. Watt-hours = watts * hours = 250 watts â¦ Then this UPS Runtime Calculator is just what you need. Introduction on LiPo batteries. The battery will last 2 hours. If you don't know the Watts or Watt-Hours, use the formulas below. The key is to use the watts you know to calculate the amps at the battery voltage . UPS runtime formula calculates runtime based on the battery capacity and the total load on the UPS. The calculator will calculate the battery life if the Watt Hour and the battery voltage is known. Laptop Battery Life Calculator Enter the Watt Hours and Watts to calculate your battery life in hours. New Features: Select and compare runtimes for four models in a single view. Your output will be displayed. UPS Runtime Calculator As you move the cursor around the chart, a popup displays runtime estimates in minutes for each load by watts. Please provide as much detail as you can with regard to the problem you found. For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. Know about hidden battery losses when estimating the energy reserve. Required runtime. Display runtime data in a table view below the interactive chart. For example, if the load requires less than 2,100 Wattsand the runtime is 15 minutes, a valid UPS will be the P30 with one Extended Battery Module (EBM) providing 25 minutes of battery backup (autonomy) runtime at the P30 maximum capacity of 2,100 watts. 3. Battery Life Calculator This calculator estimates how long a battery will last, based on its nominal capacity and the current or power that a load is drawing from it. The Load calculator displays the ideal Inverter battery combo for your home or commercial establishments. This section of the calculator allows you to figure out how many batteries it would take to give you the runtime necessary in an emergency, at the same time taking into consideration a safe 50% battery discharge rule. Actually, watts is the fundamental unit of power and watt-hours is the energy stored. Most batteries cases say something like "25C to 40C" discharge rate. Welcome to the Trojan Battery Renewable Energy Sizing Calculator. Try our Uninterruptible Power Supply Calculator and Selector Tool . Generally, battery life is calculated based on the current rating in milli Ampere per Hour and it is abbreviated as mAh. A LiPo battery consists of multipe cells. Example: Calculate the rated energy and charge stored in a UPS 12 V, 8 Ah battery and its run time if it discharges at the 2C rate.

Download the â¦ 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. NOTE: The runtime is total (standard internal batteries and optional EBMs), not additive. New Features: Select and compare runtimes for four models in a single view. 3.7 Volts. Download the â¦ The results are estimates only; the actual results will vary with battery condition, age, temperature, discharge rate, and other factors. Select a 2nd battery pack cell count if you want to check your wiring of two different packs.
