I purchased more of these to use in all my smoke detectors - and yes, they fit but I recommend checking for size as they are a bit larger. The last ones lasted 9 years. While these might seem pricey, compared with replacing regular life batteries on an annual basis, or even every 2 years, these are a great buy. Plus I don't have to climb up and down ladders to refill the smoke detectors!
I used in my bass Upright NS Design/ Thanks
The lithium battery last much longer than the regular alkaline battery. When you have it in a location such as a smoke detector, you want long life & reliability.
Do well with long life or high current use.
Good product and price.
these batteries are used in an automated production plant and have never failed.
These 9-volt batteries have a higher mah rating than Eveready, but they are cheape--even when my local drugstore has Eveready on sale. These batteries are slightly larger than the name brand, but they fit easily into the smoke detectors for which I use them. If Eveready batteries last 10 years, these must last 12 - 15 years.
