I know there must be millions of these threads but I really need an answer urgently , my friend gave me his laptop to setup stuff like windows and office after it crashed , I then plugged it into my laptops charger which had the same voltage and everything because I did not have the right converter for his charger , now his laptops battery will not charge no matter what I do , any help thanks , what must I do , if i buy a new battery will it be fixed , is it my fault???

Did you check the tip pinout on the wall wart you used? If his was positive tip, negative barrel and yours was the reverse, you have fried not only the battery, but the motherboard as well.

Get his wall wart and check the pinout.
