Lucent Technologies Enhanced VR Series Batteries
2 - 2 Product Description Issue 5 December 1998
for Emergency Lighting and Power Equipment, and UL1989,
Standard for Standby Batteries.
Features
• Bell Laboratories’ patented lead/tin alloy post, leakproof
post seal, and valve-regulated design require minimal
maintenance.
• An Enhanced VR battery consists of compact, modular cells
that permit up to 750Ah of 48V battery reserve (at a 10-hour
rate) to be installed in a single VR battery stand.
• The totally front-access, modular design allows easy
installation and growth. In addition, the removable handle
facilitates battery replacement, if required.
• Flame-retardant (UL 94 V-O flammability rating) PPO/PS
jar and cover material together with metal cell sleeves
support longer life by providing jar rigidity for
higher-temperature applications.
• Each 2-volt, 125Ah cell contains a pressure-regulating vent
located in the jar cover. The vent is covered with a porous
plastic disk that acts as a flame arrestor. In multi-cell
configurations, the vents and flame arrestors are hidden
from view by the bus bar cover.
