I have a polaroid camera from around the year 2000...where do the batteries go? I've looked and looked! I tried looking behind the film too. Is there anybody who knows?
If you're talking about a Polaroid camera that takes packs of self-developing film, the battery is part of the pack itself.
If yours isn't working, the solution is to move the film itself into a working pack. For details, see: https://danfinnen.com/article/what-to-do-if-you-have-a-dead-battery-in-a-polaroid-film-cartridge/
