I bought these in August 2009. They had an expiration date of Dec 2009. I ended up discarding half of them because by the time I got around to using them they were essentially dead. They would power a smoke detector for less than a week.

Pro: The price is right; I haven't found a better deal on 9V batteries

Con: The performance is light. I had these in smoke detectors for about 6-8 months and all went dead within a few weeks of each other.

Bottom Line: If you want a cheap, marginal performance 9V battery, this is the battery for you. I used these in smoke detectors which are wired for power, but require a 9V battery backup -- when the battery is low, the alarm "chirps", and then I replace it. Works fine for this purpose.

If you want long life and performance, you're gonna need to pay more for a better battery.

I have been so disappointed with these batteries. I change my smoke detector batteries every December 31st and never have an issue with them lasting a year but here we are April 12th and I have now replaced 3 with low power, mid you these are devices that have little current draw and should easily last a year. The last battery I took out even allowed some acid to flow out it did not hurt anything but it was trash. So I give these a VERY LOW RATING>

The pack I received as made in the US and they seem to last much longer than the Duracell equivalents. We use these with audio band equipment.

I've used Rayovac batteries many times, and have always found them to be about the same as other brands in terms of longevity (comparing them against other regular alkaline batteries). This pack of 8 was less expensive than purchasing them at a warehouse club, and much less expensive than a regular store.

The batteries come in a thin plastic case for ease of storage. I purchased them in Nov 2011 and the "best by" date on the batteries was Dec 2016.

Also like the fact that they are made in the USA. Highly recommend.

I have been pleased with these so far - they have been used to replace the batteries that came with our smoke detectors when setting up a new system. A little on the expensive side compared to generics, but that is what going brand tends to be.

I got these for smoke detectors also and they do the job for a lot less money than the two big brands.

This is a package of 9 Volt batteries that we use in Smoke Alarms. This package worked well in this year's replacement routine so I reocommend it whenerver the price is $10 or less.

They're batteries all right. They come in a nice little box and work just as well as any other brands. But for only about $13 for 8? That's an incredible steal. The store down the street sells 9v's for about $5 EACH. Next time I need 9v batteries I will just buy another pack of these. Or perhaps several packs.

I bought these to replace my smoke detector batteries. It's been a month, so far so good. Good price when compared to Walmart, Sam's, etc.
