It is an enclosed pen style battery. I am not going to open it up. How else would you expect me to find out?
Pen style enclosed battery vented/blew up???

What if they are unused? I am sure they sell them off the shelf that old or maybe not? I am going to contact SI and find out what they recommend. I only use them at home and the rest are in the stash. Or maybe I can go on here and find out. I am pretty sure they are still a vendor here.
If anyone has any info from a reputable source the li-ion batteries become more prone to explosion with age and that devices containing them should be thrown away after a year from purchase, I would be very interested in seeing that
Cells are rated for a certain number of cycles. Far beyond that internal resistance climbs. It's not measured in years; since it depends on use. For some folks, six months, for others two years.
Not to knock products lots of folks use out there (well, knocking a little) this is just one of the reasons I like replaceable batteries. Pop them out and store unused mods without worry. Keep my batteries in plastic boxes/silicone sleeves, rewrap them whenever needed, and replace them as required. Just one less potential if negligible risk managed.
Oh, always charging during the day that I'm around. I don't even charge my phone or tablet overnight while I'm sleeping.

Years matter.
The electrolyte paste dries.
The wet electrolyte paste is the conduit through which electron flow is made possible and the reason they're lithium batteries.
The higher the voltage and hotter it's stored or kept, the faster it dries.
This is what's going on when people refer to capacity loss.
When capacity loss occurs so does performance and potential for failure increases.
Internal resistance is a simple way to measure that performance available.
Though because the paste is the reactive part of the battery and is becoming inert, the potential for danger decreases while the potential for failure increases.
This is why pamawoman doesn't think this failure would have caused a fire.
It probably wouldn't have in this case.
While a lower voltage over time leaves the paste less reactive and degrades it slower, there's the potential for destroying the paste altogether.
If the paste is rendered into a state where it's not excited by electrons, it becomes incapable of storing them and allowing them to pass.
It dries up nearly instantly at a low enough voltage.
If you're walking that line, a simple drop in temperature can allow it to drop below the threshold.
A parasitic drain from the device can also draw you below the threshold.
As well, all power storage devices deplete their stored power over time naturally.
Batteries, even lithium chemistry, are no exception.
The sum of the information above is the reason any lithium batteries that are currently 3 yrs old or more should be disposed of.
These days there are some lithium batteries produced that are said to have a life expectancy of 5 yrs under normal use.
But that's only a very recent thing and depends on the variables outlined above, cell health and receiving a good cell from the manufacturer.
Those cells are only a few months old to my knowledge and have yet to prove their longevity.
Also, as far as I know, they're spec'd out by the manufacturer and installed in specific non-removable battery consumer devices and not available to the general public.
Electric cars, internet tablets, etc..

I was actually scared to use those types of mods and batteries at first. Now that I have my ProVaris I can see how they are safer. I can SEE if the outside is damaged and trash the battery. With these pen styles you really do not know until something happens. I will be working my way out of the pen style now.
I've read tons of info from legit evidence-based sources and not a single one has ever advised tossing li-ion batteries after 1 year or 3 years, for safety reasons. Yeah, they cease to be able to hold a charge. More prone to catastrophic failure, nope.
Won't be throwing away any cell pones/laptops/power tools today

I've debated and learned with dozens of people who have tested and logged thousands of lithium batteries since their inception.
Your sources are lacking very important information.
But do as you wish.
I'm not taking the same risks.
I strongly urge others to do the same.

Hopefully they even have pertinent and correct information.
It's doubtful.
Better off just asking Topwater Elvis or Mooch.
People who actually work with batteries.
Not just buy and install them.
But you probably won't get someone that buys or installs batteries from SI, either.
You'll get a PR or CS representative who's job is to communicate with customers.
Im confident I'm right.
But I hope I'm wrong.
Good luck.

It doesn't take an advanced degree in physics (which I happen to have) to determine the difference between speculative claims based on incomplete, over-simplistic understanding of a topic and evidence-based expert level understanding.
What can be asserted without evidence can be dismissed without evidence.
Pamawoman likely provided her own evidence.
I won't debate you on physics of your training.
Should be simple enough to respond in kind.

Its best to err on the side of safety and sanity when the battery in question will be shoved in your mouth.
A little research online can avoid some serious problems.
There was no evidence provided that ruled out the internal electronics or the charger as the source of failure in this case.
Also, no one has presented a shred of evidence to support this assertion that li-I batteries should be throw away after any length of time for safety concerns.
if any documented evidence or data comes along supporting such advice, by all means share it.
