After reading many negative reviews about these 9V batts, I check them for voltage and size upon receipt. The voltage on all eight batts was 9.68v, with only one reading 9.67 volts (negligible difference). The size measurements surprised me, though. I expected them to be over-sized, as describe by other reviewers. In fact, when compared to an old Duracell 9V, the Amazon batts were actually a little shorter, over-all. The width and thickness were equal to the Duracell measurements. So, it looks like Amazon has listened to the reviewers, and is putting their name on a better built battery. Longevity is another matter for the ol' wait 'n see! For now, they look good to me.

I bought these batteries for my carbon monoxide detector. One battery can only last for 10 days. So far I have used 4 batteries. Defective items. Avoid them!

These 9V batteries were relatively inexpensive but the one I've used works just fine. I don't know how long they'll last since I've just started to use the one, but if they last as long as others do they will have been a really good buy.

these batteries are for low current usage. i put one in my multimeter. It measures 9.7 Volts. they can probably be used in the fire alarms or anything that needs 9V and low current.

Good price. I checked voltage of half of the batteries and they were full charge. Don't know how long they will last but have bought other amazon basic batteries before and had no problem with them/
