An LED should never be connected directly to a battery or it will be damaged. A current-limiting resistor must be attached to either leg to prevent this damage. The value of the resistor will depend on the battery that you use and the LED that you use. Be sure that when you purchase your LEDs, they are rated for a certain current and voltage (preferably in the range of 1.5 V so that a single battery may be used).
