Hello.
Some places you can check are ham radio supply houses. I was told that
because of liability, laptop packs are expensive to make, There is a full
shut down circuit in Li-Ion packs, and there is the matter of smart
batteries, but it can be done.
I have rebuilt packs for several dozen things in the last few months alone.
Radio Shack carries a line of replace-a-cell products, and you can replace
an older,larger, set of cells, for example ni-cad, with same capacity
smaller cells, like Li-Ion. I do not recommend replacing cells with
something of smaller capacity without a firm understanding of the recharging
circuit. It would be easy to melt things with excessive charge current. One
thing I must point out, without the protective current limiting circuit in
place, an explosive situation can occur, the israli military killed one of
there foes by shorting out the battery pack of his cell-phone, this was done
by a simple tone selective reed relay.
