Excell Battery Co. exports high-reliability battery systems, primary lithium packs, and specialized energy storage modules for Colombian procurement managers and system integrators.
Colombia’s industrial landscape presents one of the most geographically diverse and demanding operational environments in South America. From the high-altitude, low-oxygen conditions of the Andean Cordillera (exceeding 2,600 meters in Bogotá and 1,500 meters in Medellín) to the tropical, highly humid marine environments of Cartagena and Barranquilla, and the extreme thermal profiles of the Llanos Orientales basin oilfields—energy storage systems must endure unmatched physical stress.
For critical infrastructure monitoring, smart gas and water metering networks (operated by municipal entities such as Empresas Públicas de Medellín - EPM, Grupo Vanti, and EAAB), remote seismic telemetry, and midstream oil & gas pipeline monitoring along the Ocensa and Cenit corridors, non-rechargeable (primary) lithium battery systems represent the only technically viable power solution.
Unlike rechargeable Li-ion or LiFePO4 batteries—which suffer from self-discharge rates of 2% to 5% per month, poor performance below freezing, degradation under persistent ambient temperatures above 40°C, and reliance on solar harvesting hardware vulnerable to Andean cloud cover or forest canopy shading—primary lithium chemistries deliver continuous, maintenance-free operation for 10 to 20 years.
Lithium Thionyl Chloride (Li-SOCl₂) primary cells offer a gravimetric energy density of up to 700 Wh/kg—more than double the highest performing rechargeable Li-ion cells. This allows Colombian system integrators to deploy lightweight, highly compact telemetry pods across remote jungle regions of the Orinoco and Amazon basins without payload penalties.
Through the natural formation of a protective lithium chloride (LiCl) passivation layer on the lithium anode, primary Li-SOCl₂ cells exhibit an ultra-low self-discharge rate of < 1% per year at 20°C. This guarantees a shelf and operational life exceeding 15 to 20 years for smart utility meters deployed across Colombian cities.
Engineered for extreme downhole drilling environments (MWD/LWD oilfield tools in the Middle Magdalena Valley basin), high-temperature Li-SOCl₂ cells operate reliably at up to +150°C and +180°C, resisting thermal runoff and internal pressure spikes under severe subterranean stresses.
Choosing the correct non-rechargeable electrochemical couple is vital to balancing continuous background current, wireless RF transmission pulse burdens (LoRaWAN, NB-IoT, Sigfox, Satellite), operating temperature, and total cost of ownership (TCO).

Colombia remains a critical oil producer in Latin America, driven by intensive extraction in the Llanos Basin (Meta Department) and traditional fields in Barrancabermeja. Excell Battery manufactures ultra-rugged high-temperature Li-SOCl₂ battery packs designed to withstand extreme vibration (up to 30G RMS) and temperatures up to 180°C. These packs supply stable power to directional sensors, gamma-ray tools, and mud-pulse telemetry units operating thousands of meters underground.
Colombia’s national modernization program for public utilities mandates automated meter reading (AMR) across major urban zones including Bogotá D.C., Medellín, Cali, and Barranquilla. Our bobbin-type Li-SOCl₂ batteries integrated with Hybrid Layer Capacitors (HLC) deliver low background current for flow sensors combined with high-pulse currents (up to 3A) required for LoRaWAN and NB-IoT cellular bursts, ensuring guaranteed 15-year maintenance-free utility lifespans.
The Ocensa, Caño Limón-Coveñas, and Cenit pipeline networks span thousands of kilometers of rugged mountain terrain and dense jungle. Internal Pipeline Inspection Gauges (PIGs) require continuous, uncompromised power for ultrasonic wall-thickness mapping and magnetic flux leakage (MFL) sensors. Excell Battery provides high-drain primary lithium packs engineered to perform reliably despite high pressure differential shocks and corrosive fluid exposure.
Operated by national agencies like IDEAM and SGC (Servicio Geológico Colombiano), remote rain gauges, mudslide early-warning sensors, and mountain seismic monitoring stations across the Andes operate without grid access. Primary Li-SOCl₂ batteries ensure continuous data logging and satellite uplink transmissions even during long rainy seasons (La Niña phenomena) when solar panels fail due to persistent cloud cover.
With dual coastline access to both the Pacific Ocean and Caribbean Sea, Colombia maintains extensive marine navigation beacons, tsunami early-warning systems, and naval coastal defense buoys. Our hermetically sealed glass-to-metal primary lithium battery modules eliminate gas venting risks, providing reliable multi-year power in high-salinity corrosive oceanic environments.
With over four decades of custom battery design and manufacturing expertise, Excell Battery Co. (a subsidiary of Ultralife Corporation) stands as a worldwide authority in primary and secondary lithium battery solutions. We operate audited, ISO 9001:2015 certified manufacturing facilities equipped with automated cell matching, micro-spot resistance welding, laser welding, and automated X-ray inspection systems.
We maintain direct distribution and technical co-development partnerships with the world's premier lithium cell manufacturers—including Tadiran, Saft, Panasonic, Murata, Molicel, Samsung SDI, and LG Energy Solution. Every raw cell undergoes strict incoming batch quality testing before pack integration.
Our custom battery designs are engineered to pass stringent international safety and transit standards—including UN 38.3 (Lithium Transport Safety), UL 1642, IEC 60079-11 (ATEX / IECEx Hazardous Locations - HAZLOC), and CE compliance, facilitating frictionless customs clearance in Colombia.
Our hardware engineers design custom protection circuits (PCM) equipped with active depassivation routines, current-limiting fuses, thermal cutoff switches, and diode isolation to prevent reverse charging or deep discharge under accidental short-circuit conditions.
Addressing technical, regulatory, import, and shipping queries for primary lithium battery exports to Colombia.
Primary lithium batteries exported to Colombia must comply with international transport standard UN 38.3. Import clearing at ports like Cartagena or Buenaventura requires accurate commercial invoices with tariff codes (HS Code 8506.50 for primary lithium cells/packs), Certificate of Origin, Safety Data Sheets (SDS), and UN testing summary documents. For equipment connected to public utility networks, compliance with RETIE (Reglamento Técnico de Instalaciones Eléctricas) may apply to the overall host device.
Passivation is a natural thin film of LiCl that forms on the lithium anode in Li-SOCl₂ cells, protecting them against self-discharge. However, when a smart meter attempts to transmit data after months of dormancy, passivation can cause a temporary voltage dip. To solve this, we engineer hybrid battery systems by pairing bobbin-type Li-SOCl₂ cells with a Hybrid Layer Capacitor (HLC) or Pulse Plus Capacitor. The capacitor supplies the instantaneous high-pulse current without voltage drop while preserving cell longevity.
Under IATA Dangerous Goods Regulations (DGR), standalone primary lithium metal batteries (UN 3090) are prohibited from passenger aircraft and must be shipped via Cargo Aircraft Only (CAO) with proper Class 9 Hazmat packaging and labeling. Alternatively, when packed inside or with equipment (UN 3091), air freight logistics are streamlined. We provide full UN 38.3 certification and dangerous goods documentation for seamless air or sea shipments.
Li-SOCl₂ offers a higher nominal voltage (3.6V vs 3.0V) and significantly higher energy density (up to 700 Wh/kg vs ~300 Wh/kg), combined with lower annual self-discharge (<1% vs 1-2%). For maintenance-free applications exceeding 10 years (such as gas meters or deep jungle weather sensors), Li-SOCl₂ is superior. However, for applications requiring zero voltage delay or operation down to -40°C without capacitors, Li-MnO₂ is an excellent choice.
We manufacture specialized high-temperature Li-SOCl₂ battery packs constructed with stainless steel hermetic casings, glass-to-metal seals, and high-temp separators. These packs are rated for continuous operational temperatures ranging from +120°C, +150°C, up to +180°C, resisting heavy shock and vibration encountered during drilling operations in Colombian oil fields.
For standard primary lithium cells and standard prismatic modules, our MOQ is flexible depending on cell chemistry. For fully customized industrial battery packs requiring specialized BMS design, custom plastic tooling, or stainless steel enclosures, MOQs typically start at 500 to 1,000 units. Prototype samples can be delivered in 3-4 weeks, with mass production lead times ranging from 6-8 weeks.
High ambient relative humidity (>85%) can cause moisture ingress and corrosion in poorly sealed battery packs. Excell Battery utilizes hermetically laser-welded stainless steel containers, IP67/IP68 rated outer housings, and military-grade conformal coatings on internal PCMs to eliminate moisture degradation and corrosion risks in coastal Colombian installations.
Colombian engineering teams can submit their load profile specifications (continuous current, pulse profile, duration, cut-off voltage, environmental dimensions) directly to our application engineering team. Our senior battery engineers perform cell-matching simulations, lifetime estimations, and thermal modeling to propose the optimal battery architecture for your project.
Whether you are designing next-generation smart meters for EPM, downhole telemetry tools for Llanos oilfields, or remote Andean hazard monitors, Excell Battery Co. delivers engineered precision power solutions tailored for Colombia.
