I installed a new battery in my Dell 7559. It was 56% to begin with. I plugged in the ac adapter and charged all night with the computer turned off (I read that is the best way to charge...is that correct?). This morning the battery is 3%. Could there be something wrong with my laptop? This is the 2nd battery this happened with - both from the same seller on Amazon. It could be their batteries are bad, but I want to see if there is anything I can try before returning. I'm running Win 10.
Thanks!
Thanks!
