The "Rolls Royce" solution to problem of the discontinued Mercuric Oxide PX14 and 2MR9. Our PX14 Adapter has the outer dimensions of the PX14 mercury battery with a recess that takes a pair of inexpensive and easily obtained silver oxide 357 cells. Buried within the PX14 Adapter are micro electronics that drop the voltage from the 3.10 Volts put out by the pair of silver oxide cells to the 2.70 Volts that your  camera was designed for.

A perfect replacement for devices such as cameras and light meters that took two pieces of the PX13 or PX625 mercury battery. This PX14 Adapter works brilliantly in the Gossen Lunasix, Gossen Lunasix 3, Gossen Luna Pro and Gossen Luna Pro S light meters.

Sadly, our PX14 Adapter does not fit the Nikon Photomic TFn nor Lunasix meters that take just one PX13 cell.

No adjustment or modification to your camera is required. The PX14 Adapter does not require activation or a supply of air.

PX14 Adapters are a one time purchase, and will last a lifetime. Simply replace the expired silver oxide 357 cells with fresh ones.

The PX14 Adapter or 2MR9 Adapter is a mercury-free replacement for the once popular Mercuric Oxide PX14 or EPX14 cell that was commonly used in cameras and light meters. Mercury cells are now banned because of toxicity and environmental fears.


There is another possible mercury free replacement for a PX14 or 2MR9 battery:
An inexpensive PX14 replacement is the alkaline battery, the A14PX. They fit perfectly but, as with all alkaline cells the voltage is not stable, it drifts down from 3.0V towards 2.70V (the voltage of the original Mercury cell) and then lower still. If you use the cell in a camera that needs a steady reference voltage, as the voltage is not steady throughout the useful life of the battery,  you need to constantly adjust how you compensate.
