The Uniross UER34615 is a 3.6V 19Ah lithium thionyl chloride primary cell in the D-cell format (Φ34.2 × 61.5 mm) — the highest capacity single cell in the Uniross industrial Li/SOCl₂ range. With a continuous current rating of 150 mA, a pulse capability of 300 mA, and an operating temperature range of -55°C to +85°C, this bobbin-type cell is specified for power-intensive remote infrastructure, smart metering, and long-interval industrial telemetry where large capacity reserves eliminate the need for multi-cell assemblies. Energy density exceeds 620 Wh/kg. 10-year shelf life at room temperature. Supplied in bulk from European stock for OEM and volume procurement.
