TLI Series long-life rechargeable lithium-ion cells
are ideal for energy harvesting

KEY  features


Energy harvesting devices require the use of a rechargeable lithium-ion (Li-ion) battery to store the harvested energy.


Standard consumer grade rechargeable lithium-ion cells have inherent drawbacks, including short operating life (maximum 5 years), low maximum cycle life (500 cycles), high annual self-discharge (up to 60% per year), an inability to deliver high pulses, and a limited temperature range (0°C to 60°C) with no possibility of charging at low and high temperatures.


By contrast, industrial grade TLI Series deliver reliable, long-life performance in extreme environmental conditions. TLI Series batteries feature:

• Longer operating life (20 years)

• Up to 10 times more life cycles (5,000 full cycles)

• Wider operating temperature (-40°C to 85°C, with storage up to 90°C)

• Ability to deliver high current pulses (up to 5A for AA cell)

• Low annual self-discharge rate (less than 5%)

• Charging possible at extreme temperatures (-40°C to 85°C)

• Glass-to-metal seal (others use crimped seals that may leak)


Available in AA and AAA cylindrical cells and custom battery packs, TLI Series Li-ion batteries provide a rugged, long-term power supply that be recharged using DC power or with energy harvesting devices.

Wireless parking meters from IPS Group Inc. harvest energy through a miniaturized PV solar panel supported an industrial grade TLI Series rechargeable Li-ion battery. These autonomous meters connect to the IIoT to permit more reliable and efficient billing and reporting. They also reduce pollution by alerting nearby motorists when a parking space becomes available.

CattleWatch utilizes solar-powered ‘smart collars’ that allow a herd of cattle to form a wireless mesh network. Ranchers can remotely manage their herd through connectivity via Iridium satellites to the IIoT. Industrial grade TLI Series rechargeable Li-ion batteries enable the ‘smart collars’ to be lighter and more compact, and thus more comfortable for cows to wear.
