No, it would overcharge and ruin the battery.
#2 You can do it by using a series resistor to limit the current.
The resistance needed is equal to the voltage drop divided by the charging current.
The voltage drop is 4, and the charging current is one tenth the battery capacity, for example for a 2000 mAh battery the charging current is 200 mA.
So the resistance needed is 4/0.2 or 20 ohms. The power dissipated in the resistor is 4 x 0.2, or 0.8 watts, so you need a 20 ohm 1-watt resistor.
The battery should be charged for at least 10 hours if fully discharged, or until it becomes slightly warm to the touch. Do NOT let it overheat.
