Customer Ratings & Reviews

This does exactly what i needed it to. My smoke alarm will not make another sound for upwards of 12 months.

Energizer is long-lasting so I always buy this brand. I use it for smoke detectors/clocks and it lasts for years.

Who needs a 9 volt? Smoke detector and carbon monoxide,that's what for Energizer blows Duracell away

Works like a charm. Able to power up a metal detector finder whenever necessary.

Reasonably priced battery pack and able to stock up for future needs.

I always buy these batteries. They end up being the most cost efficient because they really do last.

Excellent. It last longer to use . That' s why I alway only buy this products.

Not much to say about 9v batteries, but these always get the job done. I primarily use them in effects pedals for electric guitar.

I bought 3 of these for my son who needed them. No complaints yet so they are working just fine.

I use these batteries in different paranormal equipment that I own. They work very well and last a long time.
