Although the following cameras were designed to use a 1.35 volt mercury cell, they include voltage regulation circuitry and thus work correctly with an alkaline battery and do not require a mercury cell, an alternative 1.35 V cell or an adapter. Peach camera takes a single cell unless otherwise indicated.

(Many cameras and lightmeters were designed for and require a 625 mercury cell: list of cameras and list of exposure meters.)
