I bought a replacement battery for my dell Inspiron 7520. I cant find any information on how long should I charge the battery for the first time. There are some sites that say if the battery came in the laptop then you should simply charge it to full. However, if the battery came separately there are cases where the battery was stored in the warehouse for some time. As such, I have to discharge it completely and then charge it to full for 3 times.

Can anyone from Dell or experienced users give a more verifiable answer? Thanks
