Every producer of battery-powered devices states how long their product can run on a single set of batteries. They may advertise "two hundred hours," "one thousand activations," or "six months of typical use," although this information is typically offered without explanation. We want to demystify the technique so you know what it means the next time you see a battery life claim.
If the capacity of a battery is given in Watt Hours, you must also know the voltage and current drawn from the battery to estimate how long it will last. Watt is defined as ampere multiplied by voltage. As a result, if a 5-volt battery has a capacity of 20 watt hours and draws 2 amps, its output power is 10 watts (5 Volts x 2 Ampere). It will be two hours long. The calculator will compute the battery life if the battery voltage and watt-hour are known.
The battery life calculator determines how long a battery will survive based on nominal battery capacity and average current consumed by a load. Watt-hours (Wh) are also uncommon, although amp-hours (Ah) and milliamp-hours (mAh) are the most commonly used quantities for calculating battery capacity.An amp-hour, also known as an ampere-hour, is a charge unit that indicates the flow of current over a given time period. One amp is equivalent to one amp of constant current flow for one hour. Because a milliamp-hour, also known as a milliampere-hour, is one-thousandth of an amp-hour, a 1000 mAh battery is comparable to a 1 Ah battery.The results are simply estimates; the real results will differ depending on the battery's age, condition, temperature, rate of discharge, and other variables. The battery life calculator determines how long a battery will survive based on nominal battery capacity and average current taken by a load. Watt-hours (Wh) are also infrequently used, although amp-hours (Ah) and milliamp-hours (mAh) are the most often used units for measuring battery capacity.Many end users, including some electronics experts, are curious in the lifespan of their batteries. We've included a simple battery time calculator to help you figure out how long your battery will last.Battery run time is equal to battery capacity in mAh divided by load current in mA.Consider a specific example. A 2000mAh battery will last 20 hours on a 100mA current mobile phone. Battery capacity (mAh) multiplied by load current equals battery life (mAh).Important: When converting between mAh and Ah, use caution. If the battery provides Wh information, for example, 500mAh/100mAh = 5 Hours. For a 500mAh battery that operates at 0.1Ah, 1Ah equals 1000mAh.
1 When converting a battery with the same volt, Ah, or mAh, you can use the formula without include the volt.
2 The most difficult aspect of evaluating a device's use to calculate how long a battery will last is that it varies all the time.
3 It didn't matter if you were looking for a 12v battery pack run time calculator, a 24V calculator, or a 36V calculator since our formula for calculating the run times for each battery or device was the same.
Battery run time is the total amount of time a battery can sustain a certain power output. This runtime will vary based on a number of factors, including battery size, type, and discharge %.It would be fantastic to never have to charge a smartphone again. But you're well aware that batteries don't last indefinitely. This battery life calculator calculates the approximate runtime of your battery based on the following algorithm:where:The capacity of your battery is measured in ampere-hours. This number is usually written on your battery;Consumption: The average current draw of your electrical gadget, measured in amps. (If you want to learn more about electric current, try the Ohm's law calculator.)The proportion of your battery's capacity that is never utilized is known as discharge efficiency. For example, if you use a LiPo battery to power a drone, never drain it below 20% since this might be dangerous. Our battery life calculator defaults to a 20% discharge safety, but you are free to change it as you see appropriate.
Assume you are developing an Internet of Things (IoT) device that is mostly in sleep mode. In this case, you should probably figure out how long a battery will last. Simply select the advanced mode to learn more.
The awake time is the amount of time that your device is awake throughout one working cycle, such as two seconds.Consumption in sleep mode refers to the average consumption of your device when it is asleep, represented in amps. This figure is most likely significantly lower when compared to intake while awake.
