TLI batteries

The TLI battery series from Tadiran consists of industrial, rechargeable lithium-ion batteries designed to outperform and last significantly longer than consumer products. The series delivers robust performance, extreme temperature tolerance, and can achieve an operational life of up to 25 years.

Forbruker-Li-ion-celler har ofte kort levetid, høy selvutladning (opptil 60 % per år) og smale temperaturområder. Tadiran sin TLI-serie eliminerer disse begrensningene med lav selvutladning (<5 % per år), rask respons på høye strømimpulser (opptil 15 A for AA-størrelse), samt sikker og pålitelig lading og utlading fra –40 °C til +85 °C, med maksimal temperatur på opptil +135 °C for HT-celleutvalget.

Offers higher capacity combined with robust reliability, supporting up to 2,000 full cycles.
TLI-SC series
Delivers double the capacity compared to the TLI-HC series and a long cycle life when used with partial discharge.
TLI-ES Series
Optimized for maximum energy in a compact AA format. Ideal for backup and energy storage applications with a limited number of cycles.
TLI-HT series
Designed for extreme high-temperature environments with operating temperatures up to +135 °C. Perfect for oil and gas, geothermal installations, and automotive applications.

What distinguishes TLI from standard consumer Li-ion batteries?

The TLI series has been developed for industrial applications requiring long service life and robust operation.

Compared to consumer Li-ion, TLI offers:

Lav selvutlading (<5 % per år vs. opptil 60 % for consumer-celler)
Significantly longer operating life (up to 25 years, depending on use)
Wide temperature range (–40 °C to +85 °C, HT up to +135 °C)
High pulse capacity (up to 15 A in AA format)

This makes TLI suitable for long-term installations where battery replacement is costly or impractical.

Frequently Asked Questions

How many cycles can TLI batteries withstand?

Depending on the series:

TLI-A: Up to 5,000 full charge/discharge cycles
TLI-HC: Up to 2,000 full cycles
TLI-SC: High capacity and long service life with partial discharge
TLI-ES: Optimized for high energy and fewer cycles
TLI-HT: Designed for high temperatures and robust operation

Actual service life depends on DoD (Depth of Discharge), temperature, and charging profile.

How does TLI handle high current pulses?

TLI cells are designed for fast response and can deliver high pulses (up to 15 A for AA format), making them suitable for:

Wireless communication
IoT devices
Tracking equipment
Backup functions

Internal construction and chemistry provide stable voltage under load.

What role does temperature play in choosing a TLI series?

Temperature is a critical factor in industrial applications.

Standard TLI series operate from –40°C to +85°C
TLI-HT can withstand operation up to +135 °C

High temperatures affect service life, self-discharge, and cycle capacity. The correct series must be selected based on the actual environmental profile.

For which applications is TLI particularly suitable?

TLI is often used in:

Energy harvesting systems
Remote monitoring and sensors
Industrial Internet of Things (IIoT)
Smart agriculture and infrastructure
Medical equipment
Automotive and high-temperature environments
Defense and aerospace

In such applications, the battery is an integral part of the system design, not a replaceable consumable component.
