heyoall,
im currently using a dell battery 56Wh lithium battery(not sure if its called lithium, nvm), and I am wondering can I change to a 7800mAh/87Wh? They are the same voltage - 11.1V. also i looked it up(the one I want to buy) on amazon and it has this strange thing on the side ( http://www.amazon.co.uk/Battery-Dell...7022025&sr=8-3 , that longish black thing) and im not sure if it will fit? (rest of the battery seems the same, jsut that strange...part).
also it is for a dell studio 1555, basically everything is the same but the mAh/Wh, aka this one should last longer, correct?
thanks in advance!
