How Long Will My New Laptop Battery Last?


Laptop Battery run-time is difficult to determine. Actual laptop battery run-time depends upon the power demands made by the notebook ‘s components. The monitor, the hard drive and other accessories lead in an additional drain upon the battery, effectively reducing its run-time. The entire run- time of the battery life is also dependent upon the design of the laptop and all hardware plugged into the USB ports. how long do laptops lastdownload (1)

Generally, a new BatteryFuel battery will operate at least two (and usually longer) as your old battery did when it was new. Laptops and other small electronics share lighter and smaller batteries and are rated with their Volts and Ampers or even Milliamperes (1 Ampere or Ah is equivalent to 1000 Milliampere or mAh). Generally, the higher the wattage the more the Watt-Hours, but this may still vary depending upon the Amps. To find out your own battery ‘s runtime, consider the formula below.

11.1 x 6.6 = 73.26 Watt-Hours

The 11.1 volt 6600 mAh laptop battery can power roughly 73.26 g for one hour. Now to estimate how long this battery will continue in your laptop takes a different configuration of breaking up the 73.26 Watt-Hours from the notebook ‘s watts. Your notebook ‘s watts can typically be found in your guide. If your laptop uses 21.2 g per hour, your laptop will power for 3.46 hours. (73.26 battery watts/21.2 laptop watts = 3.46 hours of estimated runtime). Keep in mind that this is an estimated moment and will change depending upon the components running on the laptop and some other hardware plugged into the laptop.

You can find your notebook ‘s volt hour use at the consumer or specification’s manual. Some laptop manuals will give more than one watt-hour specification based on running the previously installed OS alone and or with another program open as from the notebook ‘s word processor. This watt information doesn’t include the use of additionally installed programs, software, and hardware. When you open up other programs and start incorporating peripherals, the run time will be lowered. Additionally, WiFi, Gaming and Video Streaming will eat up your battery power extremely fast and the notebook ‘s watt hour use doesn’t include those actions. try here
