It has a distinctive appearance with its 'stepped' concentric disks.
Confusingly, not only are the same dimensions of battery are used for Silver Oxide and Mercury cells, but often the same names are used as well! Even though the chemistries and the voltages produced are different. It is wise to take care examining the expired battery or, better still, checking with the manufacturers documentation to check that an Alkaline battery of 1.5V is required.
If you find you require a 1.35V mercury cell, you are in difficulty. Mercury cells are no longer manufactured because of their toxicity and environmental unfriendliness. Look at the PX625 page for advice.
The LR9 is the least expensive PX625 replacement. They fit perfectly but, as with all alkaline cells the voltage is not stable, it drifts down from 1.5V towards 1.35V (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 cells, you might need to constantly adjust how you compensate.
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.
Another mercury PX625 replacement is a zinc air battery. The WeinCELL MRB625 is a custom zinc/air battery designed to replace banned mercury batteries. WeinCELLs deliver the same 1.35 V voltage and stability of output as did the mercury PX625batteries so there is no need to adjust your exposure. The WeinCELL MRB625 batteries last much longer than hearing aid batteries, some times up to a year. To achieve this longer life, the MRB625 used a proprietary electrolyte and has only two small air holes, instead of the 7 larger holes found in standard hearing aid batteries.
Exell Batteries not only provide consumers with high efficiency, long-lasting performance, they also function as replacement batteries for an array of common and unique applications. Ranging from vintage camera equipment to sophisticated medical testing equipment, Exell Batteries can meet the needs of all consumers.
Exell Battery is one of the few product lines Proudly Assembled in the USA.Made with Alkaline cells, Exell Batteries will last longer and offer consumers excellent reliability.
The LR50 or 1APX is a mercury-free replacement for the once popular Mercuric Oxide MR50 (or PX1) cell that was commonly used in cameras and carriage clocks. Mercury cells are now banned because of toxicity and environmental fears..
The LR50 or PC1A cells produce 1.5 Volts, which is higher than the 1.35V produced by the original mercury cell. Most devices accommodate the small increase in voltage and function perfectly..
