I haven't measured the numbers, but it seems like something around 2x of the Dyson battery. With the original battery, we got through around 2/3 of our 1500+ sq. ft. downstairs. With the new battery, we get through the whole thing, with battery power to spare.

Can this charge separately? I want to have this battery already charged and switch to it when my other dies in the middle of cleaning.

No, the battery is mounted to the vacuum with 3 screws.

My current battery is a 2100mAh, will a 4000 mAh just give me more battery life without hurting my machine?

My tired old battery was of a similar rating. The new 5000 mAh will work just fine. Initially you will discover you can go easily twice as long between charges than before. Also your turbo-power setting will actually work for a while before draining the battery.

Is it ok to leave on the charger all the time?

I do. Light turns off when charged. Don't think you can over charge it. It has never gotten hot, I leave it plugged in all the time.
