From what I have read else where and which is backed up by the Prime cell
site is that the batteries circuitry controls whether the battery cells
will receive a charge or not depending on its current voltage,
temperature. If you put in a mix of cells that are not very close to the
same voltage to begin with the charger may not properly charge all of the
cells.

At least some packs use the same technology as is found in laptop battery
packs. Each cell is tested individually during the charging process and the
packs internal chip decides if it will be getting a voltage during the next
charging pulse. They equalize the weak cells and bring them up to full
strength while cutting power to cells that are full, or to cells that are
too hot during the charging process.

I have a hobby charger that charges RC packs much the same way. It has to
have the correct hookups to use the full equalizing process. Many say that
if the user does not push the cells to absolute deadness, and discharges the
whole pack right after a charge once in a while that balancing is not
needed. I'm not convinced on that one.
