The TLI series of batteries has been introduced by Tadiran Batteries as a new family of long-life rechargeable lithium-ion cells for two-way wireless communications in harsh environments.

The TLI series batteries utilize technology found in Tadiran’s patented hybrid layer capacitor
(HLC), which stores the high current pulses required for two-way wireless communications. This technology is modified in the TLI series batteries to deliver reliable, long term performance under extreme environmental conditions.

This is in contrast to standard rechargeable lithium-ion cells, which have inherent drawbacks including short operating life (maximum 5 years), low maximum cycle life (1,000 cycles), high annual self-discharge (up to 60% per year), and limited temperature range (0°C to 60°C) with no possibility of charging at low and high temperatures.

Features of the TLI series batteries include:

  • Operating temperature from –40°C to 85°C, with short term storage up to 90°C
  • Ability to deliver high current pulses, up to 5 A
  • Low self-discharge rate (less than 5% per year)
  • Up to 5,000 life cycles
  • Operating life of 10 years
  • Charging possible at extreme temperatures (10 hour rate)
  • Glass-to-metal seal.

The TLI series cells can be recharged using DC power or can be used in conjunction with photovoltaic solar systems or other energy harvesting devices. They are available in several standard configurations: 1550 (AA-size), 1530, and 1520, as well as custom battery packs.
