true front access batteries

Product Information

The TFA series True Front Access batteries incorporate all of the same technology found in the proven TEL series Long Duration batteries, but are packaged in a unique, patented True Front Access container.

The True Front Access® design provides a direct welded connection to the terminals for improved performance, reliability, and less maintenance.

This terminal also features the C&D Ohmic ring® which provides the most reliable testing location for technicians. TFA batteries range from 100Ah to 202Ah, fit most 19” and 23” Telecom racks, and also fit into virtually any Telecom cabinet or enclosure.

Features and Options
  • Patented Extrusion Fusion weld technology
  • C&D Ohmic Ring®
  • Long service life
  • Optional Gas Collection System
  • Versatile terminal cover
  • UL94 V-0 Flame Retardant polypropylene case and cover
  • Certified non-spillable

GENERAL
Operating Temperature Range with Temperature compensation Discharge: -40°F (-40°C) to +160°F (71°C)
Charge: -10°F (-23°C) to +140°F (60°C)
Nominal Operation Temperature Range +68°F (20°C) to +80°F (27°C)
Self Discharge Battery 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.
