Frequently Asked Questions
Is my part number TEL12-105FNS or TEL12-105FNSG?
Both forms circulate in purchasing records, and our catalog lists the FNSG build, which is what C&D's published TEL data covers. Suffix letters matter on this line because they encode the build, so send a photo of the label on the unit coming out with your quote request and the specialist confirms the exact match in writing before anything is ordered.
How does the FNSG compare with the TEL12-115FN?
They are neighbors in the same line: 104 Ah against 108 Ah at the 8-hour rate, the same M6 front-terminal hardware, the same 4,000 A short-circuit class. In practice the choice is made by what the string already contains and what the tray was drawn for, so match the existing model on a refresh and let the specialist confirm footprint on a new build.
What do the TEL series certifications cover?
SR-4228 is Telcordia's battery requirements document for network use, UL 1989 covers standby batteries, UL 1778 and UL 924 tie to UPS and emergency power equipment, and UL 94 V-0 rates the case material's flammability. Together they are the paperwork a carrier or facility audit expects a plant battery to carry, and C&D publishes the set for the whole TEL line.
