Too thick for my Acer Aspire 5742G but I knew by buying it, this is explained by the fact that it is more powerful than the original battery. So it raises the back of my PC, which is not annoying the contrary as it facilitates aeration.
Good battery life (more than 2 hours in normal use) by lot against it heats (much more than my original battery) and is therefore turn the PC at full fan.
