Wein Cell Mercury-free Replacement Batteries - new life for your old camera!

WeinCell is a revolutionary new zinc/air battery designed to replace environmentally-unfriendly (banned) mercury batteries.

Because of their extremely stable output curve, mercury cells were used in many cameras and exposure meters to ensure the most accurate exposure reading possible. But the disposal of mercury batteries has become an environmental problem, and an increasing number of states and other governments are responding by prohibiting the cells altogether.
 
Alkaline replacements don’t do the trick
Several battery manufacturers now offer alkaline batteries as replacements for their discontinued mercury cells. In most cases, the replacement does not have the same voltage as the mercury battery it is replacing (usually 1.5V instead of 1.35). And, the unstable output inherent with alkaline batteries can result in exposure errors up to 2 stops! Only Wein Cell delivers the exact voltage and stable output consistent with mercury batteries.

There is a WeinCell to replace each of the following mercury batteries: PX625, PX13, EPX625, PX400 and  PX675. Each has performance identical to the battery it replaces- exactly what you need to get those classic cameras shooting again.


Features:
 • Compatible with any camera or meter specifying the respective mercury battery
    (see battery guide).
 • Two models available; compatible with hundreds of cameras and meters.
 • Voltage output more stable than alkaline replacements.
 • No camera/meter adjustment or adapters required.
 • Up to 10-year shelf life; the Wein Cell is not activated until the pull-tab is removed
    (removing batteries from equipment and replacing tabs prolongs battery life).
 • Environmentally safe.

Type: Zinc Air. Voltage: 1.35 V.

Overview:
The Wein Cell MRB625 is a 1.35 volt non-mercury battery. It is designed to replace Mercuric Oxide PX625 and PX13 batteries and is commonly used in cameras and exposure meters. The Wein Cell MRB625 can be used in the Nikkormat F, Canon F-1, Leica M5, Olympus OM-1, Minolta SRT, Pentax Spotmatic F, Gossen Luna-Pro, and many more. 

The Wein Cell MRB625 has a distinctive appearance with its 'stepped' concentric disks. 

The WeinCELL MRB625 is a custom zinc/air battery designed to replace banned mercury batteries. Unlike 1.5v alkaline replacements such as the LR9 whose unstable output can produce exposure errors, WeinCells deliver the same 1.35 V voltage and stability of output as did the mercury batteries. In contrast to hearing aid batteries which only last 1 month, the WeinCell MRB625 batteries last much longer, some times up to a year. To achieve this longer life, the MRB625 used a proprietary electrolyte and has only two small air holes, rather then the 7 larger holes found in standard hearing aid batteries.

To use the WeinCell MRB625, the adhesive tab must be removed. This allows air to enter the cell. After about 30 minutes, the MRB625 is fully activated and ready for use.

An alternative mercury free replacement for the PX625 is the silver oxide S625PX. These S625PX cells produce 1.55V which is higher than the 1.35V produced by the original PX625 mercury cell. Because the S625PX silver oxide cell produces a steady 1.55V, you are able to compensate for the higher voltage by a  fixed number of stops or by adjusting the ASA setting. There may be as many as two f-stops underexposure by a camera that uses 1.55v instead of the original 1.35v, but the compensation you require is constant. I will be offering these Silver Oxide units later this month.
