Genesis TD — 12 V front-terminal AGM batteries for telecom

Technical specifications

Specifications are taken from the manufacturer’s technical documentation. Updated 10/31/2026. Customs codes are for reference only; the final code is determined at customs declaration for the specific model.

Description

The narrow, tall case with terminals on the front panel slides into a rack like a rectifier module and is serviced without pulling the shelf out. All connections and voltage readings are made from the front, saving cabinet depth and technician time at the tower. VRLA-AGM keeps the electrolyte in the separator, so the battery is sealed and faces its terminals toward the technician. Capacity is given at C10 to 1.80 V/cell, the usual sizing rate for telecom, where backup is counted in hours rather than minutes. Four 12 V blocks make the familiar 48 V bus. Outdoor cabinets heat up in summer, so at open sites keep charge current in check and use rectifier temperature compensation.

How to choose

Capacity follows the base station load and the required backup time, and the 50–202 Ah range covers both small nodes and large sites. When backup is short and 15-minute power matters, Genesis EP with its 348–4,189 W/cell is the better pick. For remote sites floating for years in heat, compare TD with PowerSafe SBS XL at 80–180 Ah, and a 48 V lithium alternative exists in the iON SC1048 / SC1548 series.
