# battery run time calculator

The most common formula used to determine battery life is: (battery capacity in milliampere-hours) divided by (load current in milliamperes). The predicted results will best represent actual results when using new, high-quality cells at room temperature when the estimated run time is between 1 hour and 1 year. The higher the Amp hour rating of the batteries and the more batteries that are in the pack, the longer the ride time … The results are estimates only; the actual results will vary with battery condition, age, temperature, discharge rate, and other factors. C-rate is used to describe how fast a battery charges and discharges. 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. For example, a 1C battery needs one hour at 100 A to load 100 Ah. The ride time that a battery pack provides varies depending upon the Amp hour (Ah) rating of the batteries and the number of batteries in the battery pack. The rating capacity of the same battery at 0.01C yields more amphours than the rating capacity at 0.05C, so you should care about the hour rate used in battery specification. Calculate Battery Life Watt Hours / Watts = Battery Life (in hours) Example: 60 Whr / 20 Watts = 3 Hours. Video: Battery capacity calculator: advanced mode. C-rate of the battery. The calculation to find out the capacity of battery can be mathematically derived from the below formula When it comes to online calculation, this battery life calculator can assist you to determine the time that how long the battery … Battery life will be high when the load current is less and vice versa. This simple battery run-time calculator shows approximately system runtime in hours and days, taking into account: - battery ampere-hours - the power consumption of up to three devices - system running hours per day - system efficiency The power and configuration calculator has been created to assist models in making sure they have all the information they require to purchase application matching battery packs. For an explanation of why a calculator is necessary to figure out the true run time of your battery see Puekert’s Law. No worries, if you’re wondering which online calculator to use, continue reading to determine the good battery run time calculator on which you can rely on. Enter your own values in the white boxes, results are displayed in the green boxes. A clickable product link will generate in the calculator based on the model/configuration you select. How to Calculate Laptop Battery Run Time. To use the RC LiPo Battery Power & … Calculation of battery pack capacity, c-rate, run-time, charge and discharge current Battery calculator. 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. If you open the advanced mode of this battery capacity calculator, you will be able to compute three other parameters of a battery. In order to use this calculator you will need two separate AH ratings, given by the manufacturer, as well as the amperage, in direct current of your load. CyberPower power runtime calculating tool for consumers and IT professionals. This battery energy and runtime calculator determines the theoretical capacity, charge, stored energy, and run time of a single battery and several batteries with the same characteristics connected in series and in parallel to form a battery bank.. How long will a 12V battery last? You may use the calculator to simply run through all the specifications for either one battery pack or two battery packs! Another aspect of Peukert's effect is that discharging at lower rates will increase the run time.
