The most convenient/inexpensive is the small 3 v. lithium cell, though
two 1.5 v. button cells can also be used. Anything that physically fits
the battery holder will work, and what will fit is fairly obvious if
you take the camera with you to any small-battery sales rack at discount
stores (K-Mart, etc.).
Hope This Helps
