Good battery life, unfortunately, a little thicker than the original

Basically, I recommend this battery pack. The capacity is for my Dell D430 about 4 hours while surfing the Internet.
Indeed, the battery does slightly heavier insert than the original, so that he must drüchen relatively fixed or on the battery also wobble slightly, but this is not an issue snaps into the end position. Is a bit strange that the battery is approximately 8 mm thicker than the original, so the laptop on a table not stands horizontally, but drops back. Therefore 1 point deduction.
