Pretty much like any seventies or eighties Nikon it is quite battery agnostic, and is perfectly satisfied with any of two SR44, two LR44 or one CR1/3N. The latter (lithium) are effectively the cheapest and last longest in cameras that are only occasionally used, the first (silver) last longest in a hard-worked camera - I only use alkalines (LR) temporarily when there is nothing better at hand, as they are least reliable and predictable and have a tendency to leak if left in the camera.
