HM-N Adapter (Non Voltage Transformation Type), a set of two

Please click here to see about "Japan's Consumption Tax" and "Taxes for International Deliveries"

The solution for discontinued HM-N (NR52) mercury batteries. Reusable adapter, simply change the batteries.

The adapter is the same size as the original HM-N battery.
For use with products not requiring any reduction in voltage.

Compatible batteries: Silver Oxide SR44 (Equivalent: SR44W, SR44SW, 357) and Alkaline LR44 (Equivalent: A76, AG13) 

Suitable Models: Early models of electronic shutter cameras such as Canon Date E, Canon Datematic, Olympus EC/ECR/ED, Minolta Hi-Matic E/F, Yashika Electro 35GX.
In our lab, we have not encountered any problems with exposure when using a non-transforming adapter with electric cameras.

Note :
●Battery is not included.
●Suitable for Large Currant
●This adapter doesn't reduce the battery voltage. It is not suitable for cameras with match-needle light meters. The needle tends to swing too far.

Please read and understand the following before ordering

●Some models may have unexpected limitations. Take test shots with the adapter before actual shooting. Please note that we are not responsible for any issues that arise from using the adapter while shooting.

●Old products may have poor contact due to weak spring or erosion on battery contact. Please also note that there is a possibility of short circuit depending on the shape of the battery contacts.

●Some models require a contact in the battery chamber to be modified in order to use a battery adapter. Please check the list of the suitable adapters.

●Even if you use a suitable adapter and battery, the adapter may not work if the camera or light meter is defective. Please note that we do not accept returns.

●The voltage of silver batteries (SR) hardly changes with the remaining battery charge, while the voltage of alkaline batteries (LR) decreases as the remaining battery charge becomes low. Alkaline batteries are not suitable for use in models with a match-needle light meter. Alkaline batteries are prone to leakage, so be sure to remove them when the camera or light meter is not in use.

●In order to reduce the voltage with the adapter, it needs to be installed with a battery in a camera or a light meter, and a current has to flow. Just measuring with a digital tester cannot get the reduction. 

●The voltage conversion value is based on measurements at ordinary temperature and under normal shooting conditions.
