MacBook - Lithium Polymer or Lithium Ion?

Does anyone know if the MacBooks use Lithium Ion or Lithium Polymer batteries? I was looking at buying an extra battey and I have seen it described as lithium polymer...

When I pop out the battery for my MacBook, it says Lithium Ion on the back. I would imagine the battery is labeled correctly... but ya never know.

    A lithium-polymer is actually a lithium-ion-polymer battery, so the description "lithium-ion" is correct, if a little inaccurate.

    Ah... excellent... I was trying to find batteries on Apple's site to check the specs... didn't think they would be under the MacBook itself. From what I understand, lithium polys are less likely to have the problems found with the lithium ion batteries do to the non-fluid nature of the polymer. It's just comforting to know is all.

    Li-Pos are less prone to losing maximum capacity over time. Both Intel Mac laptops (MacBook and MacBook Pro) use Li-Pos; all recently PowerPC Mac laptops still use Li-Io.



    Presumably, Apple will switch iPods to Li-Po as well, as the loss of capacity has been a frequent concern there.

    ... and less prone to the manufacturing defects that lead to burn ups.
