Has anyone used these? If so, what were your observations? How long did they last in motion and Tilt sensors?
I have not used these batteries, but I have used lesser named brands for some battery sizes.
I did see a post on another forum saying they do not work as well as top brand name batteries in high current draw applications, but they should work fine in sensors. Whether you will get as long a life as you might with Duracell or Panasonic batteries would require extensive testing. Even if they have shorter life, they might still be an economical option.
Because batteries have a shelf life, I would not purchase more batteries than you expect to use in a year or two. You would have to have a lot of devices to consume a 50 pack.
Titanium Innovations seems to imply in their brand name that their batteries have some unique chemistry, yet they use standard lithium battery technology.
My experience: I have bought many of these from Battery Junction, and they've worked well for me, lasting up to several years, depending on the sensor, in my Iris v2 (CentraLite) motion and contact sensors -- my main use for them. If Panasonic or Duracell would get me a few more days, I'm not sure I'd care by that point.
I have not used this brand of battery, but I wanted to praise Battery Junction. I don't know if it is a result of high-volume sales or a conscious effort to keep stock fresh, but of all the places I have purchased batteries, theirs are the freshest. I do not buy batteries anywhere else. I once bought some Panasonic CR2032's from Amazon and they were past the "Best by" date. That's like seven or eight years old.
I am not questioning your claim of receiving old batteries from Amazon, but to me that is surprising. Amazon sells hundreds to thousands of Panasonic CR2032 batteries per month, depending upon the number per pack. This should insure fresh batteries. However, there is always the possibility of a pack slipping through the crack (literally) and being found months or even years later, and being returned to inventory. As fast paced as Amazon warehouses operate, employees are not going to check use by dates.
Not this poster, but I've had similar bad luck. "Amazon" doesn't sell everything directly; there are many third-party sellers, and it's more likely these that are the source of problems (though in some cases it's hard to tell because they can also commingle inventory from different sellers if it's supposedly the exact same product, e.g., same UPC; in others; you can tell who sells the item and who fulfills/ships the order).
I've also received the entirely wrong product, e.g., a CR123A instead of a CR2. This is is part of the reason I've stuck to stores that are known for selling this kind of thing (like the one I mentioned). In many cases, it's even cheaper in the end, but at the very least, I can be more confident in what I'm getting and who I'm getting it from.
Just to throw Amazon a bone...I've been buying CR-2032 and CR-2 batteries from them for years and have never had an issue. I make sure I'm buying from "Ships and Sold by" Amazon. Like any other shopping platform, you need to be aware of who you are buying from.
For this round ended up going with tenergy from Amazon. For my coin cells/ watch batteries (I also have an interest in time pieces)., I usually turn to digikey, but they seemed a bit on the pricey side in this instance.
