Seems like we have dozens of remotes for all manner of things: radios, TVs, cable box, space heaters, ceiling fans, updated LED lights, car remotes, car stereos, meat thermometers, you name it. And they use over half dozen different batteries. A few are AA and AAA, but more of them are "coin" cells with different numbers. And 1632 is just one of those. Although it seems like I'm seeing this one used less often than smaller and/or thinner coin cells, I still have car remotes, a meat thermometer, and a stereo radio remote that uses them. I found some time back it pays to buy this in some kind of bulk package - at least ten. They have proven to have a good shelf life for years. Hopefully these will likewise. And at less that 50 each, they are way cheaper than the popularly advertised brands. Are they just as good? Time will tell, but out of the package, the two I have already used both measured 3.31vDC, which is what the more expensive brands measure. So my take so far is these are going to be just as good. But even if the somehow last as little as as long, they would still be a big money saver. And I have not reason to think they wont last equally as long. Either way, it is will save me money, and these batteries are easy to change on the remotes I have, so I can't think of any reason not to use these instead.

These CR1632 batteries are the correct size for the original Tile Mate Bluetooth tracker. I can't tell if they last yet, but I wrote the date on the battery when I installed them so I'll know how long they last. I'll update this review when the battery dies and I'll know if the battery life is good or not. Be sure to wipe the battery and the Tile's contacts to be sure they are clean and don't have any kind of film or other buildup that might prevent the battery from making good contact.

So far working just as well as other brands I've had before but the price is literally 4-5X lower than other options. I think I am set for life for CR1632 batteries now.
