Xeno Energy XL-205F 3.6V D 19Ah lithium standard battery with tabs

Primary power for long-life devices

The Xeno Energy XL-205F is a 3.6V D-size lithium primary cell rated at 19Ah. It suits utility meters, security systems, tracking beacons and other remote electronics that must run for years without battery changes. The chemistry delivers a high, stable voltage across most of the discharge curve. It is not rechargeable and must never be placed in a charger.

Tab termination for direct PCB mounting

Tabs on both ends allow the cell to be soldered straight to a circuit board, removing the need for a separate holder. The soldering operation must be completed in a few seconds to avoid heat damage. The inorganic electrolyte is non-flammable and non-pressurised at room temperature, though it is corrosive if the casing is breached. Operating range spans -55°C to +85°C.

Shelf-stable chemistry with wide cross-reference

Self-discharge stays below 1% per year at +20°C, supporting a shelf life of 10+ years when stored in a clean, cool, dry, ventilated area not exceeding +30°C. The cell replaces common references such as ER34615, ER34615H, ER34615C, ER34615M, ER32L615, Saft LSH20 and Saft LS33600. Do not mix different models in series and discard any unit with a mangled casing.
