Could it be done with Li-ion`s ?

Nnoooooo Please, don't do it!

This is a trick I use with lead acid batteries which modern chargers often won't re-charge.

Never, ever try to recharge an Li-Ion battery by forcing it to increase Voltage.

They are incredibly sensitive to Voltage. Without going into the chemistry that would be a sure fire way of burning your house down.

And another thing, if by some misfortune you do experience a fire with an Li-Ion battery douse it with water, or submerge it to cool the cells.

Fortunately, with batteries like the Nikon camera batteries, they are protected internally by clever circuitry which should refuse any attempt to force charge the battery if a direct connection is made.
