I ordered the regular size one, not the shorty, not the XL. It arrived today (yay for fast shipping!) but it's so long.
The battery itself is just under 5 inches. With a cart, it's 6". That's way too long for me (longer than my hand). If that's what I ordered, my mistake. I'll just deal with it. But if it's a picking problem, and I was sent an XL, I'll want to send it back for the right one. Kinda bummed as I was so looking forward to this battery.
