First purchase of these items via Amazon. I have used these before and they perform very well. They have good longevity, and I've used them for more than twenty years.

Have had the four batteries installed in my smoke detectors two weeks ago. Two days ago, one started beeping. Today the electrician indicated that possibly dust caused the connectors on one of the batteries caused the problem. At this time I'm apprehensive that these lithium batteries are not of a quality to last and operate successfully for long periods of time.

Batteries are larger than standard 9-v batteries, don't fit well
The battery bodies are longer than standard batteries. They are 4.5 cm instead of 4.3 cm. I had to force the battery into the smoke detector to get it to go in.

I was hoping these batteries where not made in China. To early to tell how they will do over the next few years. So far no problems- I purchased them in Feb. 2017
