long duration batteries

Product Information

TEL Series Long Duration batteries are designed to provide standby power to critical applications in the Telecom industry.

The TEL series long duration batteries have undergone extensive life cycle testing, including SR4228 compliance, to ensure the longest and most reliable service life possible.

With a range of capacities from 30 to 125 ampere hours and many installation options including relay racks, cabinets and more, the TEL Long Duration series is suited to a variety of applications within the Telecommunications industry.

Features and Options
  • Long service life as proven by Telcordia SR4228 testing and compliance
  • Low Profile terminals with threaded copper alloy inserts reduce height and maintenance while increasing safety and performance
  • Non-Spillable Design provides non-restricted transportation options
  • AGM Technology provides over 99% gas recombination efficiency
  • Flame Retardant case and cover complies with UL94 V-0
  • UL Recognized component
  • SLC wiring harnesses available for many TEL models

GENERAL
Operating Temperature Range with Temperature compensationDischarge: -40˚F (-4 0˚C) to +160˚F (71˚C)
Charge: -10˚F (-2 3˚C) to +140˚F (60˚C)
Nominal Operation Temperature Range+74˚F (23˚C) to +80˚F (27˚C)
Self DischargeBattery can be stored up to 6 months at 77°F (25°C) before a freshening charge is required. Batteries
stored at temperatures greater than 77°F (25°C) will require recharge sooner than batteries stored at
lower temperatures. See C&D bulletin 41-7272, Self-Discharge and Inventory Control for details.
