If you’re playing games, let’s just assume that the run time will be lower. A battery pack that stores 60 WH (watt hours) will provide you 3 hours of run time.
Lets say your laptop need 20 watts of energy to run per hour. Generally speaking this is true, but it is not the whole story. The basic idea is that 5800 mAh battery pack will allow your laptop to run longer than a battery with a 4400 mAh rating. Most laptop battery makers advertise their batteries power capacity in terms of 4400, 5200, 5600 or 5800 mAh. As long as the voltage is close it should work. The more important compatibility measurement is the voltage it supplies. The short answer is technically yes, mAh only refers to power capacity and how many milliamps the laptop battery can deliver per hour. Your laptop battery is calibrated or rather RECALIBRATED Can I replace 18650 cells in a laptop battery with a higher capacity?
It will wear out faster than for those who take better care of it (although it isn't as good for me either, who always keeps the laptop plugged in and cannot remove the battery trickle charges plus the fact that it stays basically unused, fully charged and that also makes it suboptimal)
In the worst case you may have to check disk or even reinstall your operating system (though Windows does try its best to prevent that even in the case of chronic unexpected shutdowns)īad for productivity: you may lose part of your work this way.īad for the battery: deep discharges generally are not beneficial for Li-Ion batteries (plus the charge/discharge cycles). Is it bad that I usually let my laptop battery die in the middle of work?īad for software: unsaved and corrupted data if it doesn't automatically sleep/hibernate when the battery reaches a critical level.
