checking life of battery?

[Kamaraju S Kusumanchi <kamaraju@bluebottle.com>]

1) Is there any way to check the life of a battery on a Dell Inspiron 6400
E1505? I am using Debian Etch.

2) How to find out the number of cells in the battery? The manual says it
can be "6-cell smart lithium ion" or "9-cell lithium ion". But I am not
sure which one I have.
