My laptop was N5030, not N5010 The 9-cells replacement battery(claimed to be compatible with N5030 as well) turned out to be too big for my N5010. After I had inserted the battery into the laptop, my laptop could not be flipped open. I had to ship the batter back to the seller at my own expense and order a 6-cell replacement from another vendor.
I have a Dell Inspiron N5030. The battery fits my computer, the only issue I have is when I go to charge the battery my computer will tell me not a dell battery and not want to charge the battery. I usually have to take the battery out and put back in a couple times and restart it a couple times and then it will charge the battery. I have also found that if I do not let the battery go all the way down it will usually charge without problems when I plug it in.
