Coin-sized nuclear 3V battery with 50-year lifespan enters mass production

Add the fact that Nickel-63 decay creates beta particles that cause skin burns and can damage organs. Definitely not a good choice for your watch or pacemaker.
The isotope used,Ni-63, has a half life of 100 years. It is a low-energy beta emitter with a maximum beta energy of about 66.9 keV. This places it firmly in the low-energy category which can be shielded simply by an outer layer of clothing, plastic, aluminium, water, basically anything. Probably the membrane used to convert it to electricity absorbs most of the beta particles.

I just don't understand negative comments like this one and you didn't even present something better to use a 50-year battery to power either. Just because you don't like something or have no use for it doesn't mean it's "useless". Please just keep your negativity to yourself.

The beta particles would only be an issue if the battery casing was broken, and the contents of the battery was exposed to flesh which isn't good for any pacemaker battery.
It'd be the perfect replacement for anything that uses a larger coin cell.
100 microwatts... That's 0.0001w. No wonder it lasts 50 years. For comparison, if you took your average smartphone battery of 5000mah, it would take 71 days to charge it at 100 microwatts.
The energy density is higher for sure, but until they produce a 1w cell that's small enough, the applications of thus battery are incredibly limited. I bet it's expensive too.

What level of shielding is needed?
Would actually be over 16 years to charge a 5000mah 3v battery. It produces 8w a day. This is enough to charge a typical 3v button cell in half a year. Considering most of those last over a year in remotes and such that is pretty useful. Which is probably why it has the size of a 3v button cell

I also only take my watch off in the shower, it's the perfect time to charge it, it's at 100% by the time I'm ready to put it back on, been wearing it for years.
Almost like your problem is imaginary. Or maybe the apple **** just charges slower or depletes faster.
Can it really charge that fast? I've never actually had a SmartWatch (Apple or otherwise) and always assumed it had to charge overnight... still, I'd much prefer not having to charge at all - I wear a Tissot self-winding watch that has been great for almost 20 years...
Edit: it seems like the Apple Watch takes 2-3 hours to fully charge.. not fast enough...

Most online articles disagree with the 2 to 3 hours to charge fully, I saw plenty that were saying 0 to 80% in 30-45 minutes. At least for the generations that have come out of the last few years, not including the ultra which has a much longer battery life in general.
As for my Galaxy watch in 24 hours it only depletes about 50% and that's with GPS tracking me for about 5 mi everyday. But yeah 30 minutes off as I shower and get dressed and it's at 100. Can't say it's taken over an hour even when I've let it fully delete.
You can always just go to Best buy buy a watch and if it's upsetting to use, return it within 30 days lol
I highly doubt you're self-winding watch is able to do 1% of the things that a smartwatch can do, but continue to make ASSumptions, ignore the wheel of progress, and let reviews online by random Jokers be the full methodology that you use for determining your opinion on products instead of trying them yourself.
Well, I'm one of those people who always like to have my device fully charged - just in case... so having it at 50% and thinking "good enough" won't be good enough for me...
And while my "dumb watch" can't do most of the stuff a smart watch can do, my iphone probably can... and I have it with me at all times (again, except for the shower).
I only spend 10 minutes or so in the shower by the way... I don't think that's enough charging time...

It's 50% after 24 hours of constant use, that's with the always-on display active, touch to wake and lift awake, NFC, Bluetooth, Wi-Fi and GPS tracking. After the 10 minutes in the shower, plus the time to brush my hair, teeth, and get dressed, which all in all takes about 30 minutes, it's at 100%. Not 50. 100. Or do you really take your watch off The moment before you step in the shower and then put it back on the moment you step out? Like before you've even dried off? Is your watch really the last thing you take off? Do you need to have it on while you're brushing your teeth? Doing your hair? Putting the rest of your clothes on? Choosing your outfit out? Putting your shoes on?
To expect a device to always be at 100% is just unrealistic. I highly doubt at the end of the day your iPhone is at 100%? That's what I'm talking about here at the end of a day of usage the device is at 50%, not that 50% is good enough in the morning, although it would be to get through a full usage day.
So your iPhone in your pocket allows you to quickly and hands-free see if a notification is important or not? Allows you to respond to a text without reaching into your pocket? Play or pause your music? You can see what your average speed is while running with it? Your iPhone is able to track your heart rate? Blood oxygen level? It's ready to go for you to tap and pay at a terminal when you've got your hands full? Hands-free access to a voice assistant? You can see who's calling you without reaching your hand into your pocket? Does your 20-year-old watch allow you to change your style for different events easily? Does it ever allow you to express any personality beyond this is the watch that you see me wearing every time you see me?
You just keep making assumptions. You've pretty clearly never even used the device, you have no idea how you would interact with it. Then again you seem to be terrified of not having a piece of metal stuck on your arm for more than 10 minutes lmfao
And what do you mean by just in case? Like what's the just in case scenario where you need a watch? Like what's the absolute worst case scenario that would happen if your watch battery died? You have to ask somebody else for the time? You have to use your phone? I don't know to me a just in case scenario would be **** if I get lost in the woods, I hope I have a way of contacting somebody. You're dumb watch isn't going to do anything to help you with that, a Apple watch ultra certainly would. Not to mention that having a smartwatch to use, is going to help extend the life of your phone, as you'll be using it less lol So if you're really concerned about always having battery life just in case, using a smartwatch would be more useful.
Edit: and again that battery usage that I'm talking about from personal experiences for the galaxy watch, but I know with both the Galaxy watch and Apple watch, that the battery history that you're looking at online is without power saving features enables, which if you're really worried about just in case, switching your watch to a dumb watch mode, or even limiting the function, vastly increases the battery life. Just in case.
Actually, yes, it’s the last thing I take off before showering… and no, I’m not changing my routine to suit a device - I buy things to make my life better, not to have to make compromises for them…
My iPhone is at 100% in the morning, and it charges in my car while I drive to work… and it sits on a charger by my desk… it rarely goes under 90%…
I understand I’m not “normal” - I’m not talking about everyone’s use case… just mine.
I don’t care about those features of a watch… I like the ability to TELL THE TIME as well as make/recieve calls and pay for stuff - which would be what I’d use a smartwatch for…
Again, I’m not making any assumptions- I only care about MY lifestyle… if yours works for you, great!
Just in case a power failure… or I take a trip and forget / break the charger… etc…
I never use power saving features - I want my device performing at “max” all the time.
Not sure why you are taking such offense to this…
You're living in the 90's champ. Look at Google scholar and tell me how many papers in tech/engineering originate in China.

Merry Christmas! OK maybe I don't want one in my laptop.. if the BV100 is expected to be $500, I don't even want to guess what the larger one would cost!
This is good info, I mean I would have never been aware a beta decay battery was on the market before otherwise. Nevertheless, that one has been off the market... well 3 mile island was in 1979 so I assume like 44-45 years.
As for lead shielding.. nah they are beta particles. A sheet of paper will block those, even if there are a lot of them (like you would have for a scaled up 1W version.) That said, if the BV100 really is planned to be $500, you might be right about a 1W one being for military applications given just how much it'd likely cost.

I'm a guest from this comment that you're around 60, because you certainly behave like a boomer.
You are making assumptions over and over again, you don't know what your use case would be, you haven't used it.
You assume that a minor adjustment to when you strap a piece of jewelry on is going to ruin your life. You're ignoring all of the benefits of having a smartwatch in that assumption. Like you said you used devices to make your life better, but you don't actually know if a minor adjustment to your routine would make your life better or not and you're too hard-headed to even try it out.
Also I hope you know that the way you charge your device is absolutely ruining the battery on it. So that if you ever actually do reach adjust in case scenario, your phone is likely to die extremely quickly because you always keep it at over 90%. That's a absolutely ****ing terrible way to care for lithium ion batteries lmfao
Clearly you didn't even read what I captioned, because I mentioned all three of those features in what you captioned. You would actually be surprised how frequently you end up using the other features that you didn't buy the smartwatch for. At least that's what everyone who I've ever known who's brought a smartwatch has said.
But sure you're right, you're not making assumptions
I literally said you don't have to use the power saving features and you still get over a days the earth of use, which is more than your iPhone gets. And using those features on your smartwatch, just turn it into the basic dumb forking watch that you wear right now.
Your whole just in case you forget or break your charger is literally fixed with the power saving feature, because if that ever happens you can just switch it into the same exact dumb watch mode that you have currently and it will more than likely last you until you get back. Literally being undone by your own stubbornness over and over again lmfao
At least with Samsung too the whole fear of losing your charger is completely irrelevant since any single Samsung phone works as a charger with reverse wireless charging for Galaxy watches
If you care so much about your devices running at max then why are you using a watch that isn't capable of running at max?
You're ignoring all of the benefits of smart watches over the most ridiculous of insecurities lol it's just hysterical to keep laughing at you and your whole head in the dirt ignorant *** this is the way I've always done it so nothing else could possibly be better huh derrrrrrrrrrr attitude
I’m in my 40s… talk about making assumptions… that would be YOU… again, I’m talking about my own use case - why are you so hot and bothered over this? Do you get a commission if I buy one?I'm a guest from this comment that you're around 60, because you certainly behave like a boomer.

That wasn't an assumption or a genuine estimate of your age, it was a diss that clearly went miles over your head lol
You can't talk about your own use case, you've never used it lol
You're like a grandpa who refuses to get a cell phone because they've already got a landline so they assume they know everything about cell phones
You should learn to read since I already answered your last question lol
Again… hot and bothered… dunno why…
I’m gonna guess you’re in your early twenties and think the world revolves around you…
