This is the battery for Leaf AFi / Hy6 and Hy6 Mod 2 cameras with the Leaf battery contacts in the grip arm battery compartment.
These batteries are supplied directly from DHW and are not aftermarket. It will also fit the Leaf AFi digital backs.
Note: Some Rolleiflex Hy6 and Hy6 Mod2 cameras were fitted with the Leaf Aptus style battery contacts such that users of Leaf AFi digital backs could keep a single battery type and charger instead of two sets. All the AFi camera bodies will have the Leaf battery contacts.
