Query: Nice Battery!

This battery lived up to what I expected that is most sure! Yes it is the size of two original batteries stacked on top of each other but I kinda like that since now it is elevated and is nicer to type on and gives the fan more room so it seems as it has been staying cooler than before. that is a plus! Shipping seemed to take forever, but it seems like if you pick the slowest method it always takes around a month to get to you. oh well, I love it and that is what matters. Lasts at least 3.5 to 4 hours. depends on how much i use it...
