I need a windows 10 professional laptop for high school and would like it to be hopefully under a thousand dollars. Though please list even if it is above a thousand dollars.
The laptop must have the following specifications below:

-i5 or i7 6th generation intel core processor
-a long lasting battery that lasts up to at least 9 hours.
-8GB or more RAM (4GB is ok too as long as I can add more)
-the battery must be user replaceable
-the screen should be bright (300 nits or higher)
-military grade durability/spill resistant keyboard

Thanks so much for your time!
