    Received my shipment quickly... except when I opened the package I received EXACTLY what the picture shows. Yes, that 9V package is open and empty. Please explain how I received this rather than 12 9V packaged batteries? I especially like how there is a Duracell in there! LOL!!

    Not much to say other than these batteries works great. It's a lot better than "duracell". I would rather buy these from now on.

    I got 9V Insignia battery (12 pack) from Best Buy when they had special sale for that. The Insignia batteries have very much the same quality with other brand name such as Duracell. Highly recommend !

    did not last at all. One of the worst batteries I even purchased. I put in my items and less than 6 weeks was dead. Was all 4 Smoke Detectors , That were also hard wired so battery should not have died so fast..

    Like everyone else, I like to change the batteries in my smoke detectors at least once per year, sometimes twice. I have a 4 bedroom home so there are a lot of detectors. The reviews said that these batteries were as good as "name" brands for a fraction of the cost. They were correct....very pleased.

    Best buy at Best Buy! I had hunted and hunted for the "best buy" on these batteries. I go through quite a lot of them for my smoke alarms and they are so costly everywhere else.
