Oniza CR1632 3V Lithium Coin Battery (8 Pack) - Long Lasting Button Cell for Watches, Key Fobs, Remote Controls & Medical Devices - Perfect Replacement for Car Keys, Calculators & Small Electronics

I got these for a step tracker. they have held up under constant use for months. With the value pack, I figure I won't need to buy any batteries for that device ever again. It will wear our or fail first.Greetings. We use these ONIZA CR1632 batteries only in our Polar FT4 and FT7 heart rate monitor watches whenever we go walking, swimming and/or biking. Sometimes we may get in two of these activities in in the same day. Hence they’re used quite a bit more in our watches than say other watches that just tell time. They would probably last longer in those watches. I wouldn’t know how they fare in other applications such as car alarm o key fobs, etc., but from reading some of the reviews, they seem fine for that too.They typically last us anywhere between 9-12 months used in our application and that is consistent with any of the more popular and more expensive name-branded CR1632 batteries such as the “copper topper” or the “bunny” ones.They are a decent deal for the price and this is the second time we’re ordered them so I would recommend them.Cheers!These are like any CR1632 batteries you can buy, just cheaper and you get more of them. I've bought similar ones before and there has been no problem with longevity, usually about 3 years or so, for Lexus cars and SUVs. I expect they'll last for years as the batteries Amazon sells are good long term.Bought these for my finger flashlights. They work perfectly and I've had them in for a couple months still running full blast! Will definitely use product again.These button cell batteries are a good value. I have had them for a month in a car remote and they are still working. Obviously I use them everyday so they are holding up pretty well I would say. You get 8 so these will last me a long while. I don't have anything negative to say at all. It's a battery and it does it's job.Seems to work in my car key fob! Excited to see how long they last!I used them for my key fob. Still working months later. Other brands i felt like i had to change every monthBought these to replace the dead batteries in my Tile Mate tags. They seem to work great so far. Time will tell if they last for a long time or not.
