If yours wasn't a special length then it would be 4 3/4 inches, (121mm). I fear you may have discouraged people from buying it by complaining of the length and that you wouldn't use the 1000mah because of the length and then misstating the length so that they would have a false impression when they do comparisons.
With all respect, that was my concern.
It measured pretty close to 5. It really is quite large, and I stand by my statement of getting the 900mah over the 1000mah. It topples over easily, and is just too large, as you can see in the video.
If you remember from the video, it stuck out from the bottom of my hand quite a bit, and it doesn't sit comfortable. You really can't stand it up on a table, since the littlest jarring will topple it over. Basically, it is too thin to be so long. It just doesn't work well in this style battery.
