Note: For F4-series cameras, Nikon offers three versions - 1) Nikon F4E with Multi-Power High Speed Battery Pack MB-23 containing six AA-type alkaline or NiCd batteries, or NiCd Battery Unit MN-20; 2) Nikon F4s with High Speed Battery Pack MB-21 containing six AA-type alkaline or NiCd batteries, and 3) Nikon F4 with Battery Pack MB-20 containing four AA-type alkaline batteries. Note: Nikon advises only using AA-type batteries with the Nikon F4, do not use lithium batteries, but daring many users have reported no significant differences using such batteries. However, as this is a technical specification of the camera issued by Nikon and should always be the reference guide. The site maintainer does not suggest/encourage/reporting (nor be held responsible) such possible combination is viable, if you insist give it a try - use it at own risk.
