MiA,
That's capacity loss NOT charge loss in Diagram A. That's permanent capacity loss.
"The speed by which lithium-ion ages is governed by temperature and state-of-charge. Figure 1 illustrates the capacity loss as a function of these two parameters."
Also on the same page:
Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
But immediately after that it also says:
[FONT=Verdana, Arial, Helvetica, sans-serif]"If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge."[/FONT]
So those are key factors, as indicated by the preceding statement
"The speed by which lithium-ion ages is governed by temperature and state-of-charge. Figure 1 illustrates the capacity loss as a function of these two parameters."
So yeah, it's far from exact enough to set one's clock or
really high hopes by, but the chances of the batts still being plenty or at least reasonably useful after a relatively long period (especially welcome if they couldn't be obtained legally at all anymore), just aren't bad per se, so hey why not.
While it's definitely good for people to know what the ideal conditions and treatment are for these batts, I think it's also very good for them to be made aware that a
little batt stockpiling is not in fact illogical or destined to be useless. And as far as stockpiling for ban purposes, many aspects of it just
are a gamble, i.e. guessing how many atties will last you or how long unflavored high nic juice really will hold up. But those kinds of things aren't stopping the countless folks who do at least want to give it a shot and see how far they can make it.
Big batt mods will suit that mission much better of course, but having some extra ecig batts on hand as well makes sense
enough, except for those who would actually be financially impacted by purchasing and setting aside a few extras that may possibly never get used. (And with long-term prognosis not being
all that bad, having a couple properly stored extras on hand to add to rotation within just weeks or months as currently-in-use/abuse ones give out probably isn't an
entirely bad idea either. Again, unless one would be impacted financially by any batt that didn't end up serving a useful/fully useful life.)
In the end it's all another matter of opinion I guess, as to whether it's worth the relatively small expenditure and risk that it will have been a total or almost total waste. But I do think ppl should be permitted more often than they seem to be to know all sides of it, and that they do have more than one (reasonable) choice.
