High Energy Density Silver-Zinc Cells Yardney,
Pawcatuck, Connecticut

• Innovation
• The firm has developed a lightweight high
  energy density battery
• optimized for the high cycle life and high
  energy density requirements.

• Accomplishments
• Energy Output 40-90 watt-hours per pound and
  2.5-8.0 watt-hours per cubic
• inch, depending on cell type, model and
  conditions of use as much as 120
• watt-hours per pound and 11.0 watt-hours per
  cubic inch for certain special
• models and applications.
• Power Output From 50-150 watts per pound and
  4-10 watts per cubic inch
• (continuously) for "LR" Type Cells, to
  150-500 watts per pound and 10-35
• watts per cubic inch (continuously) for "PM"
  Type Cells. On an intermittent
• basis, values two times the indicated power
  output are possible (i.e., 1000
• watts per pound and 70 watts per cubic
  inch).
• Open-Circuit Cell Voltage1.82-1.86 volts when
  fully charged, 1.61-1.63
• volts when partially charged.
• Nominal Voltage Under Load m 1.5
  volts.
• Plateau Voltage Regulation 2 at a fixed
  load and temperature limits
• within 10F
