I have a total of 4 Drift Cameras 2-Stealth HD170's and 2 Ghost have never had an issue with any of the cameras. But the last 2 weeks my oldest Ghost on a couple of occasions wouldn't turn off so i had to take the battery out to get it to work. Noticed the battery was super tight in the camera and had to shake it like a ketchup bottle to get the battery to come out. Was putting in a new micro sd card in my new Ghost and the battery just pops out when you open the cover.So i took the old cameras battery out and noticed it was slightly swollen. Ordered a new battery for it and put it in the camera yesterday slipped in and out easily. Sent Drift Innovation an e-mail letting them know of the problem. Got an e-mail this morning letting me know to attach proof of purchase and they would send me out a new battery. So it looks like i'll have a spare battery. But :thumb::thumb: to Drift.
