TLI Series

Delivering robust performance and 20-year operating life that is unmatched by consumer grade li-ion batteries.

TLI Series industrial grade rechargeable Lithium-ion batteries are designed to
outperform and outlast consumer-grade alternatives — delivering robust
performance, extreme temperature tolerance, and able to reach 25-year operating
life.

Consumer grade Li-ion cells have drawbacks that include short life, high self-discharge rates (up to 60% per year), and narrow temperature limits. In contrast, Tadiran’s TLI Series rechargeable Li-ion batteries address these limitations with a low self-discharge rate (<5% per year), fast response to high current pulses (up to 15A for AA-size cells), and safe, reliable charging and discharging from -40°C to +85°C, with max temperature up to +135°C for the HT cell range.

Tadiran’s TLI portfolio has a wide range of solutions to meet growing demands in
IIoT, smart industry, and mission-critical remote applications:

• TLI-A Series: designed for maximum cycle life in harsh environments, delivering up to 5,000 full charge/discharge cycles, ideal for solar-powered devices and long-term remote deployments.
• TLI-HC Series: offers higher capacity while maintaining robust reliability, supporting up to 2,000 full cycles.
• TLI-SC Series: delivers double the capacity of the TLI-HC range and long cycle life with partial discharge usage.
• TLI-ES Series: optimized for delivering maximum energy in a compact AA- size form factor. Ideal for backup and energy storage applications with a limited number of cycles.
• TLI-HT Series: designed for extremely hot environments with operating temperatures up to +135°C. Ideal for oil & gas, geothermal, and automotive applications.
