The quality of this item is excellent considering the price.

is going well up to this point.

These alarm batteries appear to be of high quality and worked well for our alarms.

This item works exceptionally well!

I initially loved these batteries because they were affordable and appeared to be well-constructed. However, they have not held up well in use or while sitting on the shelf. I recently opened a new package to replace the battery in my smoke detector and found that all of them were below 7 volts, with the lowest being 4.3 volts. I bought them in March, so they should still be good. It's possible I got a bad batch, or maybe not. It seems that you truly do get what you pay for, so I will not purchase these again.

These batteries have been powering my smoke detectors for years, and they continue to perform excellently, with a long lifespan of a year.

I purchased these for my fire alarm and they are working well so far. I plan to replace the batteries in a year if needed, as they are supposed to last for a couple of years according to the details.

I have used two of these batteries so far. When I received them, I measured the voltage and found both to be fully charged. They were well packaged and seem to be well-made. I can't speak to their longevity yet, but they seem to be a great deal for good batteries.
