Designed to adapt two 6x3mm magnets and an LR44 battery into the [XX]640 form factor.
Make sure there is good contact between the magnet and battery, the adapter will not work if there is no continuity between the magnets and battery. Clean any high spots or burs that could separate the battery from the magnets. I just used a small flathead screwdriver as a scraper.
Fitment was validated using an Olympus 35 EC.
Thanks!
