    Well, unless a battery doesn't work, then I'm usually happy with it :-) And in this case, there was a rebate offer, so I was able to take advantage of that. The batteries work as expected.

    On my way out of the store I’m found a rack of batteries and remembered I needed a few 9V. Product placement was key and helped me a lot as the rest of the batteries are in the back of the store.

    I buy the 9v max battery energizer every year for my smoke detector. I prefer putting a new 9v battery when the time changes. It’s easier for me to remember when it’s been changed.
