    Energizer batteries seems to last longer than Duracell batteries. Glad Best Buy carries them.

    I feel like these didn’t last as long as Duracell. It felt like every other day I was replacing them.

    I am constantly buying these batteries every year. I swap them out on the fall back for daylight savings time in all my smoke detectors. Safety first in the house.

    What is there to say besides they are batteries and they work well? I wish they lasted longer but that is more an issue of my kids leaving their toys on when they are done playing with them than the battery’s performance. Overall, I like them.

    9 volts batteries are used less and less now. And I suggest getting the Energizer for the overall quality of the battery

    I normally purchase and use "The Dollar Store" heavy duty 9v batteries (2 for one dollar) for my grandson's toys. But when I need a high drain battery for my guitar pedals, or for our smoke alarms, these are my "go to" choices.

    This is a quality brand that you can not go wrong with when you choose to purchase it. You will not be disappointed with it! We wouldn't choose differently if we had to choose again.
