This article contains online calculators that can work out the discharge times for a specified discharge current using battery capacity, the capacity rating (i.e. Introduction on LiPo batteries. The resulted total watts can be used to decide the type of generator or UPS battery you require to meet the shortage of electricity. For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. After estimating daily usage we need to consider which type of battery will work best, as they have unique performance characteristics and are sized differently. New Features: Select and compare runtimes for four models in a single view. Are you trying to find the battery runtime for an Eaton UPS? 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 2. A 4S LiPo would therefore supply 14.8V. A LiPo battery consists of multipe cells. 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. 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). (you can calculate this using the equation: 44.4Kw/30 = 1481W) 3.) This information can usually be found via a sticker on the rear of the device, a tag on the power cable, or from specifications listed on the manufacturer's website. Know about hidden battery losses when estimating the energy reserve. Select the standalone battery voltage, V – ‘standalone’ means a single battery. A 0.5C or (C/2) charge loads a battery that is rated at, say, 1000 Ah at 500 A so it takes two hours to charge the battery at the rating capacity of 1000 Ah; A 2C charge loads a battery that is rated at, say, 1000 Ah at 2000 A, so it takes theoretically 30 minutes to charge the battery at … 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. UPS runtime is a ratio of battery capacity (AH) over … 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 … 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. Print this page. 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 Online electrical energy calculator that allows you to estimate your home or office backup power supply requirements.
