I bought 1 pack of 3V batteries for my alarm sensor, it requires 3V, and thought I bought the correct one as advertised for this product. After I changed the battery the alarm panel keeps beeping as if the battery wasn't changed at all. Then I thought it could be the sensor rather than the battery so I called my alarm guy out, he checked the problem and found that the Duracell battery I bought isn't quite 3V as advertised so it keeps losing the signal. I had to pay for the alarm company labour + new battery which I had to fork out £118, when it could have been avoided had the battery been 3V. Hope this is just a one off case. But it is really bad when it says 3V but it's actually 2.78V. Total frustration!I bought these for our Danalock smart door lock which takes 4. Product orignally came with Panasonic Industrial CR123 batteries which lasted a good year of heavy use. After 5 months of light to no use, these things are dead. Just replaced with more Industrial batteries and rolling again... lock opens and closes with power and doesnt sound like its struggling. Expiry date on this battery claims to be 2030, so should be well within their usage date. Avoid these and buy something decent if you have a 123 cell product which needs decent output. Not what I'd expect from DuracellI ordered these batteries thinking that High Power was something special. Indeed some Duracell batteries come marked "Ultra" or "High Power" or "Made in Japan". These took over a week to arrive from Barcelona and were made in China. I would complain that there is nothing to suggest they are High Power but the photo on Amazon says Long Life and not High Power, so wysiwyg. These might last for years in my Carbon Monoxide Alarm but they are nothing special. Next time I will order some cheaper Energizer ones that will arrive within 24 hours.CR123 or 123 sized batteries from Duracell are brilliant batteries. They are advertised as "Up to 40 % more power" & they certainly don't dissapoint. I use these in my pocket torch for use during winter months. The torch assists me with vehicle checks (I am a bus driver who needs to check the vehicle every morning), and use the torch while on excersise with the Army Cadet Force. I require batteries which are reliable & long lasting. There are obviously cheaper CR123 batteries out there, but if you need quality & reliable batteries for your items, these are certainly the ones to go for. When these run out in about 1.5 - 2 years time, I will reorder the same ones. Highly recommended.These state Arlo compatible, but we're down to 90% right after installing, and within a day I was getting warnings that the batteries need replacing. Don't trust. Something not right. Perhaps they're not rated for lower winter temperatures, I'm not sure, but I certainly won't be buying again.
