TLI Series

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

TLI Series industrial grade Lithium-ion (Li-ion) batteries address the inherent drawbacks of standard consumer grade rechargeable Lithium-ion cells, which include 5-year maximum operating life and/or 500 full charging cycles, high annual self-discharge (up to 60% per year), a limited temperature range (0°C to 60°C), an inability to deliver high pulses, and no possibility of recharging at extreme temperatures.

TLI Series Li-ion batteries can deliver up to 20-year operating life with 5,000 full recharge cycles. These batteries can also store the high current pulses required for advanced two-way wireless communications, and have an extended temperature range of -40°C to 85°C, with storage up to 90°C, under extreme environmental conditions.

TLI Series cells can be recharged using DC power or teamed with photovoltaic solar systems or other energy harvesting devices to deliver reliable long-term power. TLI Series batteries are available in standard AA and AAA configurations, and custom battery packs. Remember, TLI is not your standard rechargeable battery and is recommended only for the toughest assignments.
