Just Imagine What These SilverCell® Advantages
Can Do For Your Application
LIGHTWEIGHT — Silvercels weigh anywhere from one-third to one-fifth that of nickel-cadmium and lead-acid cells of a comparable energy output.
COMPACT — Depending on size and conditions of use, to do the same job, our silver-zinc cells will only require one-half to one-fourth the space of the other widely used rechargeable cells.
POWERFUL — Silvercels (silver-zinc batteries) can be discharged at tremendously high rates. This combined with their high energy output, makes them ideal for such high-rate applications as missiles, space launch vehicles, torpedoes and torpedo targets.
STABLE VOLTAGE — Because the impedance characteristics of the silver electrode vary little with the state of charge, silver-zinc batteries provide a stable operating voltage until nearly all the capacity is withdrawn.
SAFE — We are very proud of the fact that our silver-zinc cells have not ever caused or contributed to any serious accident
RELIABLE — Silvercels have been used on dozens of critical man-rated applications, such as the Extravehicular Mobility Unit (EMU), Manned Maneuvering Unit (MMU), NR1 and DSRV submersibles.
RUGGED — Silver-zinc batteries can be used on applications with very demanding dynamic exposures as evidenced by their widespread end use on so many missile and space launch vehicle applications.
RECHARGEABLE — Silver-zinc cells and batteries can provide hundreds of charge/discharge cycles under ideal operating conditions.
WIDE SELECTION OF SIZES — Silver-zinc batteries are available in an almost endless variety of ampere-hour sizes and prismatic shapes. Many other cells (0.1 to 20,000 ampere hours) are available in addition to the “standard models” listed in this brochure.
VARIETY OF CELL TYPES — Silver-zinc cells come in three distinct classes of cells: “LR” for maximum cycle and wet life, “HR” for greater high rate capability, and “PM” to optimize rate capability for applications not requiring many cycles or an extensive activated life.
PACKAGING ADAPTABILITY — With the variety of sizes, shapes and types, the individual cell concept allows you to arrange series strings of cells in a silver-zinv battery to provide any voltage desired.
CUSTOMIZED CELL DESIGNS — In addition to the cells listed in this brochure, for optimized performance, Yardney routinely provides customized silver-zinc cell pack designs for any cell size.
