Hello,
a good computer consumes 4.7 A, and the new battery: 4000 mAh
I just want to know how to calculate the autonomy that this battery provides (in hours) thank you for your response :p

    Hello, it's relatively simple when you know a bit
    4000mAh = 4Ah
    4Ah/4.7A=0.8510638297872340425531914893617 hours
    0.8510638297872340425531914893617*60=51 min

    Your autonomy will be 51 minutes.

      Finally, 51 minutes is quickly said because if we take into account the startup time and the reserve that the computer keeps to shut down safely, it should rather be around 40-45 minutes.
