The one in the computer is ok
the spare is a different story

Wikipedia lists over 20 different Lithium chemistries.

I think there was concern over laptop batteries, but commercial
realities overrode them. Briefly at one stage laptops were not allowed
as cabin luggage and have to be in the hold with the batteries removed
and securely separately packed.
That didn't last long.
Just what are the airlines most profitable passenger type ?. And what
is that passenger likely to be carrying so they can work 'on the go'. ?
As it is, when going though airport 'security' (at least in Australia)
you have to unpack your laptop and they xray it separately - presumably
checking to see that you haven't turned it into some sort of incendiary
bomb or something.
But try an ship a lithium battery by courier - then you will find out
that they are not allowed on aircraft and have to be shipped by road,
and they have to be consigned and signed for as dangerous goods. This
has affected the shipping of certain types of equipment at work - the
gadgets containing lithium batteries can no longer be shipped by 'next
day air'. The transport companies won't accept them.
