Re: cache batteries

[DrFranken <midrange@xxxxxxxxxxxx>]

The shortage was an FAA problem. They suddenly declared that shipping 
LI-ION batteries by air was illegal due to several fires on aircraft 
shipping batteries. Oddly all were NiCad batteries but... The FAA didn't 
notify anyone that this rule was coming either so, shortage.

So when that happened all the suppliers (mostly in China) were forced to 
ship by boat. This of course fu-bared the supply lines and caused many 
shortages as the batteries were now weeks away instead of a day or two. 
That entire pipeline then had to be filled up. The pipeline is full now 
so the problem is solved pretty much.

I say 'pretty much' because vendors are also not allowed to ship LI-ION 
batteries in a charged state. This means that often when you get them 
installed they need to charge before the cache is available. THIS means 
you'll want to do this during VERY Low I/O load time periods or there 
will be performance pain.

On a side note you do know that it's Illegal to place a spare laptop or 
phone battery in your checked baggage? And if you bring a spare with you 
it must be in the factory packaging. (Now who really has that any more???)

If you've ever seen video of a Li-Ion battery exploding you'll 
understand why Batteries Plus et-al doesn't work with them. Most of the 
folks there would end up on a bad You-Tube channel.
