    It’s batteries. A respectable brand will always provide much better battery life. I do love the price match that BB offers.

    Energizer is a name brand that you can't go wrong with it. The 9V batteries are great for smoke detectors, I have used them once every year. Great product!

    I have had a hard time finding batteries that would last for over 12months in my smoke detector. Mine have just passed 14 months and I haven’t heard a chirp yet.

    Best Buy seems to be getting out of the battery business. There is very limited choice of products. If you think you will have a continuing need for them, consider stocking up now. Buying a multi-battery package also brings down the cost per battery considerably.

    It was that time of year again when one's battery operated fire alarms need changing and this package was the perfect fit. The price was the best around as well.
