I just read this tome....huge amount of info.
I did notice the math assumption was wrong at one point in particular:
There was an assumption that (Back then at ~ 16 k members) as CPF had 10 battery failures for ~ 16k members, that that represented a ~ 1 in 1,600 failure rate. (For PRIMARY Lithium cells)
That would only be true if each member had only one battery in their life time. I think its fair to say that most of the members here have had far more than one battery. The stories represented EVER having a problem with a battery in this context.
It seems we have had fewer incidents since 2006, etc....and that either the lights and/or the batteries are built so as to minimize this occurrence, and/or the info on safe handling has reduced the number of incidences due to poor handling procedures, etc.
In any event, it at least seems like Lithium Ion Batteries have become reasonably safe to use when handled properly. NON-Lithium Ion Batteries have had equivalent examples of failure it seems as well, and it seems that batteries in general need to be treated with the proper respect for the package of power they represent.
