  It depends ;-)  I've purchased "bare" 18650 lithium cells without
protection circuits, and I know laptop batteries generally have
circuits,  no idea about the BP-5Ls the Nokia tablets use.  When I was
talking about lithium cells not being able to tolerate overcharge I
was talking about the bare cells themselves-- not as part of a
finished assembly like the BP-5L.
