Re: cache batteries

I had only heard of Li-Ion battery fires. Apparently, YouTube has just
about anything. Even though I was expecting an explosion, it was still a
surprise. I had read where people could rebuild battery packs, and
warnings were included.

Here is one video:

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.

Also, about a year or two ago, cache batteries were as rare as hen's
teeth. IBM couldn't get them. Another reason not to wait until they go
failed. I am paying maintenance - therefore it's not my responsibility

to

go to Batteries Plus (my wife's boss' parent's chain) and have them
construct one.
