Product Overview

The Tadiran TLI‑1550US is a 4.0V rechargeable lithium‑ion (TLI) cell engineered for ultra‑stable, long‑life industrial IoT applications that require exceptional cycle life, high pulse capability, and reliable operation across wide environmental conditions. As part of Tadiran’s TLI‑1550 family, the US variant is optimized for ultra‑stable performance, enhanced safety, and long‑duration autonomous operation, making it ideal for embedded systems powered by energy harvesting or intermittent charging sources.

High‑Stability Industrial Li‑ion Chemistry

The TLI‑1550US uses Tadiran’s proprietary industrial‑grade Li‑ion chemistry, designed for harsh environments and long‑term cycling rather than consumer electronics. Key characteristics include:

• 4.0V nominal voltage with a stable, predictable discharge curve

• High cycle life, often 5,000+ cycles depending on depth of discharge

• Ultra‑low self‑discharge, enabling long standby periods

• Fast recharge acceptance, ideal for solar, vibration, RF, or thermal harvesting

• Wide operating temperature range, typically −40°C to +85°C

• Long calendar life, often 10+ years in field deployments

The “US” designation reflects ultra‑stable performance, particularly valuable in systems requiring consistent recharge behavior and long‑term reliability.

Electrical Performance for Rechargeable IoT Systems

The TLI‑1550US is optimized for low‑average‑current devices that require periodic high‑current pulses for wireless communication. Electrical advantages include:

• Stable 4.0V output for modern low‑power electronics

• High pulse capability for radio bursts (LoRa, NB‑IoT, BLE, Zigbee, etc.)

• Excellent recharge acceptance from intermittent or low‑power energy harvesters

• Predictable cycling behavior with minimal capacity fade

• Reliable operation in extreme environmental conditions

This makes the TLI‑1550US ideal for autonomous IoT nodes that must operate for years without manual servicing.

Mechanical and Environmental Durability

The TLI‑1550US is built for rugged industrial environments:

• Hermetically sealed stainless‑steel construction

• High resistance to shock, vibration, and mechanical stress

• Excellent performance in both extreme cold and heat

• Long shelf life and stable long‑term cycling

• Compact cylindrical form factor for embedded designs

Its durability ensures reliable operation in mission‑critical, remote, and maintenance‑restricted deployments.

Typical Applications

The TLI‑1550US is widely used in rechargeable, energy‑harvesting, and continuous‑duty IoT systems, including:

• Wireless sensor networks (WSN)

• Industrial IoT telemetry and monitoring nodes

• Smart city infrastructure (lighting, parking, environmental sensing)

• Asset tracking and geolocation devices

• Energy‑harvesting systems (solar, vibration, RF, thermal)

• Security and intrusion detection systems

• Medical and wearable devices requiring long cycle life

• Remote monitoring and SCADA subsystems

These applications benefit from the TLI‑1550US’s ability to deliver years of rechargeable, maintenance‑free performance.

Why Engineers Choose the TLI‑1550US

• Rechargeable 4.0V industrial Li‑ion chemistry

• Ultra‑stable performance for long‑term IoT deployments

• High cycle life with minimal capacity fade

• Fast recharge acceptance for energy harvesting

• High pulse capability for wireless communication bursts

• Extreme temperature resilience (−40°C to +85°C)

• Proven reliability in industrial and mission‑critical systems

The TLI‑1550US is selected when designers need a rechargeable, ultra‑stable lithium cell capable of powering autonomous IoT devices for a decade or more.
