Yes Armando, batteries are a problem with the D1 series. I just bought a new Nikon EN4 from B&H. It was close to the total cost of the D1. I didn't know Nikon still made them but the new one had a date code of 1202 which I think is Feb of 2012. My next newest has a code of 0612 which I think is Dec of 2006. I've had it for a few years for my D1X IR.
