Present credible evidence on why i should purchase 3 year old batteries.
You've only demonstrated that it is easier to destroy a creditable assertion than to present one..
Original poster: Man I just got in a minor car wreck. Glad it wasn't worse, I could have been seriously hurt!
Internet: Well, yeah dummy, that's why you should throw your car away when it's more than three years old, and buy a new one.
OP: What? I've never heard of that before.
I: *presents as evidence, footage of fiery car crashes, without context*
OP: But what does any of that have to do with how old the cars were?
I: Trust me, I know more about this than you do.
OP: All I'm asking for is some evidence.
I: Look it up, stupid.

I go by what mooch said when he was asked when to stop using a battery. His answer was when the length of charge was so short it ...... you of. He is who everyone says is the expert.
Yes.
The expert here.
Not the only one here, mind you.
Just the only one slaving for the good of the forum.
Yet, in other endeavors there are dozens doing similar, if not more extensive work.
And they have answers to that same question that go into details of logs and graphs so extensive you'd have to read through 5 years of their posting history.
Guys with $20,000 to $100,000 toys suspended in mid air depending on knowing exactly when that battery is too risky.
And knowing exactly what their flight time will be on that battery.
Me?
My face
My house
My children
Maybe my wife on certain days (I kid)
All worth more than their toys.

Actually,
the OP asked questions specifically about automatic ego style batteries and received good answers.
I musta missed the throw them away if they're 3 years old comment, obviously if someone said that they were confused or uninformed.
Long term storage of the specific batteries the OP was asking about does increase the likelihood of reduced life, inoperable units and malfunction & failures.
As the OP found out they most certainly can go thermal when they malfunction.
Then somebody entered the thread with all sorts of tangential examples & misunderstanding looking for an e fight.
All the batteries we use lose capacity as they age (even unused), at a faster rate when used, even faster when pushed.
What started life as a 20a cell could be an actual 19.5a or 7a by the 50th cycle depending on how it was used.
Why would I present evidence on an assertion I never made? I never advised anyone to buy anything nor throw anything away. If I were to offer such advice, I would provide some sort of supporting documentation upon request or state frankly that I have none. I would not take it as some sort of personal insult that someone would want to better understand the basis of why I think what I think and then hurl ad hominem sat them.
I have purchased used cell phones and laptops. Sometimes the battery has failed (as in fails to hold enough charge to power the device, not explode) in less than 300 cycles and sometimes the battery continues to charge, discharge and power the device sufficiently after 3000 cycles. Sometimes there are visual indications that the battery should not be used like swelling. I have read a lot of literature both scientific and lay about li-I batteries and have not seen any info that supports the idea that batteries are more prone to catastrophic failure (aka exploding) after a certain age. I realize I don't know everything there is to know about.. well..anything, which leads me to want to learn more.
I would not advise anyone to purchase used electronics unless they were comfortable with the knowledge that the might have to replace parts - parts like batteries - or that the device might simply be beyond repair.
It does not appear that I will be learning more or gaining valuable knowledge from this thread.
I wasn't aware any cell phone or laptop could draw 15a - 30a from their batteries.
Guess you didn't hear about samsung cell phones going thermal in such an amount they were recalled & pulled from market.
Never even heard of a laptop that didn't have a quality battery management/monitoring system.
Like power tool battery packs do.

Just like with cell phones and e-cigarettes there are plenty of videos of exploding laptops. There have been recalls by pretty much every major laptop brand over the years - the latest being hp, I believe.
Pardon the interruption I just got an answer from the great people at Smokeless image. i had a feeling they would let me know because their Customer service is always outstanding. Anyway, this was their answer about storing them long term and how long they will last if used daily.
good morning in answer to your question before you store them you will want to fully charge them use them for about 15-20 minutes because at a full charge with storage your battery cells will drop faster over a longer period for storage also you never want to put a battery in high or lower temps here is a link on how to store battery's if you would like to further research it BU-702: How to Store Batteries – Battery University as for the ones you use daily we normally say they last 3-6 months we also have a 90 day warranty but often they exceed that time frame but is not a guarantee if you have any other questions or concerns please let us know have a great day

So no direct answer as to how long they can be stored, then.
Sorry to hear.
Battery U used to have a page on temperature, time and voltage vs capacity loss in a lithium cell.
A user named Bill Delong did extensive testing on these theories and posted most, if not all, of it over on ultimaterc.com if you're interested.
Could give you much better answers than you received.

Expecting them to last 3 to 6 months doesn't seem to show much confidence in their battery and charging setup. 90 to 180 charges, if charged daily, should not be an excessive burden on a properly designed battery and circuit. Given the age of your units, I guess you're well past the warranty period.
Look, the issue to me is this. If I see a new/newish non-abused Li battery fail I'm quite surprised (failures almost always from "abuse" in the sense of used outside their safe envelope). If I see an older battery fail, especially during charging, I am less surprised, although in a perfect world it would never happen.
I would assume 45 to 720 charges.
Maybe the person rotates devices, maybe it gets charges 4 times daily.
But that leaves nothing of how long they can sit waiting to be used after the last one fails or is retired.

I have the good new stuff. I just prefer the good old stuff. LOL. Got some more new stuff on the way.
Fixed that for you.
I'm not trying to put you down, you have gleamed incorrect information. Most of the battery fires we've heard about come from batteries that were charging. What many people don't realize, and the notion of "get a regulated device, it's safer" has only led to further misunderstandings, is that most(if not all) of those fiery failures were from devices with built in batteries/chargers or from the 510 chargers. As to the age of your batteries, as long as you understand that the older your devices are the higher probability of the battery or the charger failing, I think you'll be okay.
Think about it this way, which would you expect to perform better, for longer, a $30 device whose sole function is to charge batteries or an onboard charging component that is a part of a $30 device?
Thank you for your timely responce.
You challenged the statement of another very informed Poster.
Are you not obligated to defend Your statement?
With a degree in Physics, I'm sure you have vast knowledge on the subject. Why not share it with us?
Just disappointed.
I cast no aspersions on the participating players..
