Lucent Technologies Round Cell Batteries
2 - 2 Product Description Issue 3 December 1999
Overview, continued
Features • Slow-growth, pure lead grid
• Patented, life-increasing grid geometry
• Water-impermeable, PVC jar
• Unique, high-strength jar-to-cover seal
(bond strength >1000 lbs per linear inch of seal)
• Patented, leak-preventing post seal incorporates epoxy sleeve, rubber
boot, and patented tin-alloy
• Unique, transparent circular jar
• Nonconductive, acid-resistant, polyester-glass stand
Benefits • Extended life:
– Unique grid design results in a cell capacity that actually
increases with age during float service. After 15 years of
service, Round Cells have a capacity greater than when
originally installed.
– Cell lifetime exceeds any other battery available today.
– No derating is required (20% derating typically required for
most other batteries).
• Minimal maintenance:
– 10- or 15-year intervals between water supplements
– Leak-free history of nearly a million installations over 25 years
– Cursory inspections recommended for cleanliness and corrosion
– Transparency enables visual inspection for crystal growth
– Time-consuming specific-gravity checks are eliminated
• Safety/standards compliance:
– Designed to minimize the hazards of fire and electrolyte
leakage
– Flammability rating: UL94V-0, ASTM D 2863, 33% LOI
– Seismic rating with specific Round Cell battery stand
• Easy installation:
– Space-saving, lightweight polyester-glass stand snaps together
• High reliability:
– Plate capacity increases over time. Jar size allows for 3% grid
growth before contact, resulting in a battery life that extends
well beyond 40 years when maintained properly.
