Description
Many vintage cameras were designed to use 1.3v mercury batteries, which are no longer made. Blix’s favorite alternative is zinc air, which offers a pretty similar 1.4v that stays stable over the life of the battery.
The main downsides of that Zinc air are:
The batteries will run down in a couple months whether or not they are in use, and
Specialty drop-in replacements are usually pricey.
This 3D printed adapter solves that second problem. By taking a standard size 675 zinc air hearing aid battery and adding a 3D printed adapter, an off-the-shelf Size 675 hearing aid battery becomes a perfect fit for vintage CdS meter cameras. We offer both drop-in replacements, or the adapter by itself if you would like to supply your own batteries. These batteries usually last for a month or two of use, and are cheap to replace.
The EPX625G mercury battery in the pictures is for reference only and not included in the listing.
If you order an adapter with battery included, make sure to remove the blue tab before use!
Happy metering!
