Voniko Alkaline Battery 23A - Ultra 23A Batteries (6-Pack) - Long Lasting 12 Volt A23 Battery for Doorbells and Power Remote

I have garage door openers, camera's burglar alarms plenty of 12v batteries. I have used hundred of these small 12 volt batteries. All burglar sensors use them. I am required to replace them every 6 months NO MATTER the brand. I purchased 30 20 10 different brands 1 and 2 packs of Name brands and they ALL last about 6 months. The barn alarm often has difficulty operating properly, especially in winter. Kind a ok i forget to turn off that alarm prior to entering and half the time it does not set off the alarm. I purchased about 10 of these. Put 1 in the barn sensor over 2 months ago and it is winter/cold/cold winter. THAT SENSOR WORKS EVERY TIME NOW. I still forgot 2 times came back in the house and alarm is sounding. I tested it 2 times IT WORKS EVERY TIME. The barn sensor is about 120 feet from the alarm station. I WILL BE USING THESE FOR AS LONG AS THEY CONTINUE TO WORK SO WELL. I have no idea why but they are significantly better. And it matters. I do not know how long they will last in a garage door opener, most last longer in those. But many are a pain to get to work every time I use the opener control? Most of what I have been using are foreign made. I believe these may also be but who cares they work better. And that is how product purchases should be made: quality which I try to do most of the time. I would have been buying name brands if they lasted longer or worked better but never found any better than all others Until Now!
