disposal of Universal Waste (category defined)

There may be a big-box electronics seller near you where they accept
small batteries from computers, cameras, and so on. You may have to
call and ask; or see if site links such as the above direct you to exact
locations where these products get returned for recycle & reuse.
Some sites and service providers charge a fee in association with the
handling of this class of product; since all batteries should be recycled
and various metals and chemicals should not go into a landfill. Also,
to inquire of the computer specialist in your area about this topic may
be helpful in the proper disposal of e-waste. Information is available.
{The actual chemical component of the iBook battery should not be too
different from any other li-on portable battery; that probably would be no
problem to include that cell with others of that kind/type in the same bin.}
Good luck & happy computing! 🙂
