You need both. The extended case on the larger AH rated versions very often gets in the way under the hood. Also be acutely aware that the battery is NOT an extended handle. If you pull on it enough times, then one or both of two things can and will happen. You'll either ruin the detents in the ratchet case that hold the battery in or you'll ruin the locking tabs on the battery that snaps into the detents. Almost nothing is more annoying that getting something all lined up in a difficult spot and then having to stop and pop the battery back in.
If your defense of that silliness is that we all know cheaters are longer handles and designed to be pulled on, then go away now and stop talking to me since that is the answer I got from more than one idiot I cautioned.
