What is the best portable battery for 3-4 recharges?Dell Inspiron 7559
When i bought this laptop i expected a battery life of 10 hours, but only with a browser on, it drains within an hour and barely goes on for 2 hours with battery saver on.
So now i wanted to go out and relax and use my laptop for at least 3-4 hours.
Can anyone suggest a good portable battery charger ?
Also how much should power battery should i get?
My specifications are :-
Information about each currently installed battery
SERIAL NUMBER 1642
DESIGN CAPACITY 73,997 mWh
FULL CHARGE CAPACITY 70,589 mWh
CYCLE COUNT -
Let me rephrase : -
What battery should i select from Amazon with my specifications ? I don't understand the convention of mWH and mAH. They require voltage to be convertible and i don't know which one to take
Is this a good question?
