It may be used to calculate the run duration of devices that demand a certain amount of watts or amps. In Wh it will give 3V*1A = 3 Wh - 2 batteries of 1000 mAh,1.5 V in parallel will have a global voltage of 1.5V and a current of 2000 mA if they are discharged in one hour. The input voltage of the inverter should match the battery voltage. t = duration in hours. If not, then it can be measured as; Volts x ampere hours (Ah) = Watt hours Example 1: A 4,400 mAh 11.1 volt battery Divide the mAh rating by 1,000 first to get an Ah rating of 4,400/1,000 - 4.4ah. Create report -Name how to calculate watt hours of lithium battery. Battery Size: I have this (app) application and I need it to run for (X) hours, what size battery will I need? You may need to calculate the lithium metal content (or lithium equivalent content) . Watt-hours(wh) =Voltage(V)*milliamp-hours(mAh)/1000 = 3.7*3000/1000=11.1wh. Multiple factors are necessary to consider that we mentioned here. Here's how to calculate its watt hours: 33 Ah 12 V = 396 Wh So the battery has a capacity of 396 watt hours. Formula, Battery Wh = Battery Ah * Battery Volts, So for this example, I'll take a 12v battery as an example which is the most common one, 200Ah * 12 = 2400Wh, How many kWh is a 200Ah battery? For sure, the backup may lasts up to 4.8 hrs at 100% efficiency. Watt-hour(wh) calculator. To know the size of a Lithium-ion battery, you need the load current, duration, and remaining charge. 0.75 grams/cell x 6 = 4.5 grams of lithium in the battery. Below are the formulas for calculating same. So, a battery with 3000mAh and 3.7V nominal voltage will have a watt-hour rating of 11.1wh. Watts = Ah*battery volts. amps = watts / ohms. Say, 5AH*3.7V/10 Watts = 1.85 hrs With 90% Power efficiency for Li-ion/LiPo batteries.
