3V Battery Holder 1

Summary	Main Characteristics	Notes - Related Units
This external battery holder can be used to keep the electrical shutter and metering system of the OM-2 or OM-2n running under extreme low temperatures.	It consists of a Battery Holder that accepts the two battery cells from the OM-2(n) and can be closed with the Battery Chamber Cap of the OM-2(n), connected with a 147cm cable to a plug that can be screwed into the Battery Chamber of the OM-2(n). This allows the photographer to keep the external battery holder in his pocket, protecting the batteries from voltage drop due to low temperatures. The OM-2(n) mechanics will function in temperatures as low as -50 degrees Celcius.	This unit can only be used with the OM-2 or OM-2n. A Winder or Motor Drive cannot be used when 3V Battery Holder 1 is attached.
