    Got these to put in my smoke alarms around the house. I feel better using these Energizers than some off brand product that may need replacement sooner. Reliable and economical. Great!

    I had to get these to put into my fire alarm at my apartment. It was beeping every 30 seconds, and the property manager deemed it not important enough to get it taken care of by maintenance SMH

    I ran out of 9V batteries and needed to buy some more. The Energizer brand is the best and I was happy that Best Buy carried them. After using some rewards I had earned, I wound up paying a great price.

    Our Smoke/CO2 detectors use a 9-volt. If you have not replaced yours recently, these may be a good time to replace yours at a reasonable cost.
