I have a Energizer e2 Photo battery type: 1CR2 3v... I bought it for our alarm system only to find out it does not take that kind of battery (shucks!) and can't return it anymore since I killed the packaging. Does anyone have a need for it? If you want it reply to this email with your email address and I will email you back to get your mailing address.. (This is better than just keeping it or throwing it away.) -- Thanks, Bradley
