The 400/500 'Books use a flat pack (part # 616-0114 on the pack) of four 
rechargable cells (VL2330 cells.) If building a replacement pack, keep in 
mind you must use VL type replacement cells. Regular Lithium cells (such 
as those used in cameras, etc.) are _NOT_ suitable.

The later TiBooks use a single LiIon cell (marked MH2210, from a 550 I 
have in front of me) attached to its own little charging controller PCB. 
The entire package (cell and PCB) is normally replaced as a unit, though 
I reckon one could replace just the cell if one could find a source.

Either pack type is readily replaceable, they're located just above the 
optical drive. Remove the bottom plate and lift out the optical, 
easy-peazy. The PRAM batts are stuck in place with double-sided tape, 
just a bit of pulling and prying will unstick 'em.
