بطارية Wein Cell MRB625 1.35 فولت (PX625 و PX13)

My old Canon F-1 finally works again with these zinc-air cells—the 1.35V output is spot on, and they fit the PX625 slot perfectly. Just remember to peel the tab and let them sit a minute before use.

My old Canon F-1 had been sitting idle for years because I couldn't find these anywhere, but the zinc-air chemistry in this MRB625 fired it right back up. It's a relief to have the correct 1.35V again instead of risking the meter with alkaline substitutes.

Finally found these 1.35V zinc-air batteries that fit my Canon F-1 perfectly, and they powered right up without any voltage issues. The mercury-free design is a nice bonus for safety, and the battery life seems solid so far after a few days of shooting.
