EEMBCR123A 3V Lithium Battery Non-Rechargeable CR17345 CR123 Battery High Performance with PTC Protection for Cameras Flashlight Toy Alarm Smart Sensors(4)

Super batteries that are what they say they are, not trying to be beyond the capabilities of current physics.Arriving in a brilliantly packaged cardboard box, that contained a plastic insert showing the batteries off perfectly in a way that was never going to allow them to discharge against something metal, nor come into contact with water.Reaching for my trusty plastic packaging opener (box/Stanley knife), I was pleasantly surprised to discover that the plastic tray (insert) was in two halves and by pulling on the two opposing tabs came open easily - why can't everyone use this method? It deserves an extra star just for that!Even better, every part of the packaging (both from Amazon and EEMB) can be recycled with easeThe batteries were exactly what they claimed to be - DO NOT BE FOOLED BY OTHERS!There are sellers out there that may wish you to believe that a battery of this size (or much larger) could be of a far greater capacity (say 15,000mah), and when you see it your immediate thought is "That's great, best I've seen - and cheap too!" then you add it to your cart. When you then get the battery and try it you're disappointed that they don't seem to last very long, and perhaps put it down to a bad batch (after all, these do exist) and you buy another to get one that works.I am a tech geek.I have been working in the electronics field for over 40 years.I am constantly on the lookout for new technologies - and things that will run accessories I have for longer.Believe me when I say this simple fact:- "Such large batteries simply DO NOT EXIST!"- If these batteries did exist, they'd be the standard for everyone, not the exception!!!The batteries that came to me today were perfect, and after a quick test on a bit of kit, I have confirmed that they were (I told you I was a Geek!).The list of batteries that's available from EEMB all seem (from reading their specifications) to be on par with the correct available batteries from outside the Amazon environment, and I will certainly be looking to them in the future for anything that I need to obtain quickly and from a reputable company.There are other things to consider...This company is called "EEMB", and has been on the Amazon Storefront front long enough to amass over 22,000 reviews - this isn't a company called something incomprehensible like "GingGangGoolieGoolie-123" that's only been on the site for a few days with barely any reviews, and then disappears after a few months!According to "Fake-Spot" (an add-on that is not associated with either EEMB or Amazon), which analyses all the product reviews, the company history, products on sale, etc) it scores a B+ using a random sample of 100 products from its store. That's one of the highest scores that I've had the pleasure of seeing for an entire store (don't forget that other companies can employ a "Bot" to write fake negative reviews to bring down the overall score so that it makes it look to be on a par with other stores).EEMB Store can be found at this URL (Not sure if it will be a clickable link in the review of not):https://www.amazon.co.uk/stores/EEMBBattery/page/ABA6D6FE-10F3-40E4-94B9-9099DEE09F49At this time I cannot give full 5 stars to these batteries for "Longevity" nor "Battery Life" as I have not had them long enough; I have based these scores on what my readings are from the equipment that I tested them in. If they exceed these projected figures I will happily come back and amend this review to reflect real-life answers.This product, according to the same analysis tool, scores an "A"This product, according to what I have seen so far, and what I hope continues, also scores an "A" - if it were possible I would give it a full "A+"(Beyond a simple "A" it can become silly, as people say "A+" only to be outdone by the next who says "A++" and then "A+++++++++" et al.I believe that "A" is the highest you can get, and EEMB deservedly get that from me - well-done everyone, I hope that my faith in this product is borne out when I purchase other items from you.Now I must go and check on what other batteries I need and start to get them ordered from both here and an external site so that I can run a comparison between the products that I receive and therefore will be able to see how things stack up in future.Cheers!(Just for clarity, I was never in the Scouts. I am also not associated in any way with any company mentioned in the above text, nor anyone that is selling via any online outlets that I am aware of)

Good quality. Lasted a good time.

Sorted out what I wanted them for

Amazon came through again for me in finding these batteries, which were for my home security system. Arrived next day, reasonably priced and batteries work well. Can't comment yet on length of performance, but very happy.

It's a battery! It works great in my tracker.

I purchased these less than 2 weeks ago and installed one in the ring door sensor. It’s now complaining the power is low and the battery needs replacing. This is not good enough !

Bought this set of batteries for my monimoto device (Tracker) they were a little bigger in size to the batteries I took out (about two to three mm wider) so bit of tight fit. Other than that seem ok can't comment on longevity of batteries hopefully will be ok time will tell I will update if need to.The batteries come well packaged in a cardboard box and then in clear plastic tray with lid so easy to store.You cannot charge these batteries so don't buy this type if that is what you need.I have had them fitted in my device for over a week now and still getting full strength reading.

Used in Ring door sensor. Original lasted years, this one needed replacing after 6 months...
