Yes, according to the rough comparative measurements I was able to make (the photo of the 505 battery is angled, so it wasn't perfect), that battery is the same size as the 600 one in the photo. It's a little weaker, though, only 750mAh instead of the 840mAh the 600 battery in the photo seems to have. Though, if you're battery is dead, I guess it's better than nothing
