I am getting a laptop for high school and want to know how long this battery will last. The specifications say that the battery is 2-cell, 37.2 Wh Li-ion.

Thanks for your help!

It depends on how much power your laptop use. For example, if your Laptop use 12W of power, your battery will last for 3.1 hours (37.2Wh/12W = 3.1h).
