Charged up and inserted into my Ixus 105. I shot 167 photos (keeping my finger held on the shutter, without flash). Then recorded 38 minute video (seems to be the cut off point of the camera) and started recording another video reaching nearly 30 minutes before the battery icon began flashing. All with screen brightness at max. Not compared with the standard battery, but seems more than sufficient as a spare battery to have at hand.
On the battery I received there was no obvious branding indicating it was "Invero" branded. Came in a generic yellow box with the words "digital video battery" and a sticker stating "fits NB-6L".
