Default I bought this laser

I bought this laser module from ebay
3VDC 532nm Green Beam Laser Lazer 50mW 60mW 70mW Diode Module Stage Ligting | eBay

I'm wondering if I can hook up the red and black wires right to 2 AAA batteries or if I need to buy something else first, and what would the connection look like?

Connect the black wire to the negative end and the red wire to the positive end of the battery.
