Enter the battery capacity and runtime units in our Battery Life calculator to estimate the number of battery life hours left. These interactive runtime graphs make it easy to see the amount of battery runtime available with or without optional battery packs. mAh Battery Life Calculator is an online tool used in electrical engineering to precisely calculate battery life. Calculate Battery Life Watt Hours / Watts = Battery Life (in hours) Example: 60 Whr / 20 Watts = 3 Hours. 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. The rating of the battery reduces by approximately 62% if it is discharged in 1 hour. This calculator is based upon 12V … You’ll need to know how much power (in Watts) your UPS is delivering. UPS runtime formula calculates runtime based on the battery capacity and the total load on the UPS. A 4S LiPo would therefore supply 14.8V. 2.) UPS Runtime Calculator As you move the cursor around the chart, a popup displays runtime estimates in minutes for each load by watts. Online electrical energy calculator that allows you to estimate your home or office backup power supply requirements. Most batteries cases say something like "25C to 40C" discharge rate. Fill out the remaining box’s for the 2nd battery pack and then hit the submit button. Laptop Battery Life Calculator Enter the Watt Hours and Watts to calculate your battery life in hours. The results are estimates only; the actual results will vary with battery condition, age, temperature, discharge rate, and other factors. UPS Runtime Calculator To find the UPS unit that's right for you, enter your equipment's load in WATTS or AMPS or VA and the number of minutes that you need battery backup for in case of a power failure. Then this UPS Runtime Calculator is just what you need. Please provide as much detail as you can with regard to the problem you found. So if a 5 Volt battery has 20 Watt Hour rating, and, it draws 2 Amp current, then the Watt delivered by Battery = 10 Watts ( 5 Volts x 2 Ampere). The key is to use the watts you know to calculate the amps at the battery voltage . Print this page. This tool shows Estimated Minutes of Runtime along the vertical (Y) axis and Load by Watts along the horizontal (X) axis. If we are using a 24V system that draws 1,152 watts with two 50Ah batteries in series (100Ah total), we would use the following equation: 1,152 watts draw / 24 volts = 48 amps drawn at top speed 100 Ah / 48 amps drawn = 2.08 hours of runtime New Features: Select and compare runtimes for four models in a single view. New Features: Select and compare runtimes for four models in a single view. 1. 20-hour rating, 100-hour rating etc) and Peukert's exponent. Apart from the cells, a discharge rate is defined by the letter 'C'. Select the standalone battery voltage, V – ‘standalone’ means a single battery. The UPS runtime formula can be used to estimate if the number of devices can be supported for the length of time needed. Battery Life Calculator Feedback. A LiPo battery consists of multipe cells. The power consumption of a device will be listed in either Watts or Amps. These cells deliver approx. The third factor that will be taken into consideration when measuring the runtime of your battery will be the system itself – in other words, the inverter and the wiring that connects the device to … BU-503: How to Calculate Battery Runtime . Model Specific Calculator: Calculate the estimated run time or battery backup time of specific Battery Backup Power, Inc. UPS (uninterruptible power supply) models using the load in watts and the model/configuration drop down. When you move the cursor to any point along the line, a popup bubble shows the Runtime Estimate with the load in watts and the runtime in minutes. The battery size calculator derates the battery linearly based in this characteristic. Giving the necessary data we will deduct that each cell needs 247W. NOTE: The runtime is total (standard internal batteries and optional EBMs), not additive. The calculator assumes you will need to size your system to get you through average amount of sun-light in the least sunniest month of the year for your location. Select the right UPS for your home, home office, small business, Server Room and Network Closet, or Data Center Facility. 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 … The resulted total watts can be used to decide the type of generator or UPS battery you require to meet the shortage of electricity. The Load calculator displays the ideal Inverter battery combo for your home or commercial establishments. 1,000 watts x 10 hours per day = 10 kWh per day Check out our off-grid load evaluation calculator . Video: UPS’s cannot accommodate an infinite battery capacity.

Download the … 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. Your output will be displayed. For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. Luminous has a comprehensive range of inverter and batteries to fulfill your power backup requirement. Watts per Battery. 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. Select a 2nd battery pack cell count if you want to check your wiring of two different packs. 3. The number of batteries you need depends on the capacity of the batteries you choose to enter into field 18. 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.
