Up for sale is a LOT of 2 Tadiran TLL-5903 iXtra Li-SOCl2 Lithium 3.6v AA 2.4 Ah Batteries with wire axial leads. 

These are the same size as an AA battery (ER14505), but they are not your typical household AA battery. 
These are 3.6v batteries and 2.4 Ah.  These are NOT rechargeable. 
These have the wire axial leads on each end as pictured.  (about 4.5 centimeters long each end). 
The size measures approximately 14mm diameter x 50mm length.
These are manufactured in 2019 but are brand new, never used. 
They have a shelf life of about 30 years.   I tested a batch of them and they all tested about 3.68v.  They are rated 3.6v.
I have a lot of these available in case you need a different or bigger batch of them.  Just ask.
For more technical data on Tadiran batteries, go to their website.  I can't post the link here. 
See photos of exactly what they look like.    These are exactly the batteries you will receive, so look at the photos. 
TL-5903 replaced the TL-2100 model. 
One purchase gets you 2 batteries.  Ask me if you want more. 


Lithium thionyl chloride (LiSOCL2) chemistry stands apart due to unique performance attributes that make it ideal for applications such as electronic toll tags, RFID, environmental monitoring, mil/aero, smart grids, automatic meter reading (AMR), wireless mesh networks, system control and data acquisition (SCADA), data loggers, measurement while drilling, oceanographic measurement, and emergency/safety equipment.
Utility meters (elect., water & gas) „ Automatic meter reading „ RF systems „ Sensors & monitoring systems „ Tracking systems „ Wireless security systems „ Automotive electronics „ Industrial electronics „ Ultra Low Power (ULP)  ...etc...

Tadiran batteries feature an annual self-discharge rate of less than 1% per year, able to power certain low current draw applications for up to 40 years under the most challenging environmental conditions. As a result, Tadiran LiSOCl2 cells are the PROVEN choice for use in remote locations and challenging environments.

Tadiran long life lithium batteries enable remote wireless devices to operate maintenance-free for decades.

Extended life with moderate pulses

Tadiran iXtra Series lithium thionyl chloride (LiSOCl2) batteries are ideal for low-power applications that must operate for up to 10 years while requiring moderate pulses.

iXtra Series batteries deliver extremely high voltage (3.6 V) and high energy density (730 Wh/Kg) to support product miniaturization. These extended life cells feature low annual self-discharge along with the ability to generate moderate pulses by harnessing the passivation effect. These ruggedized cells feature the widest temperature range (-80°C to 125°C) to perform reliably under extreme environmental conditions, along with a hermetically sealed can to deliver superior leak prevention vs. crimped seals.


These are not your average batteries. These are the world’s most energetic, longest lasting, high performance batteries.

Perfected through decades of R&D and refinement of proprietary manufacturing techniques, long-life Tadiran lithium thionyl chloride batteries can deliver an annual self-discharge of just 0.7% per year, while competing batteries have a self-discharge rate of up to 3%. 

The battery technology pioneered by Tadiran is unique, enabling design engineers to pack more power into less space… combining unparalleled reliability, long operating life, and powerful performance.

Tadiran lithium thionyl chloride (Li/SOCl2) cells feature:

• Longer life…Tadiran batteries feature an outstanding shelf life and long-term reliability. As a result, Tadiran batteries can operate up to 4x longer by harnessing the passivation effect.

• Greater energy density…Tadiran lithium thionyl chloride batteries offer the highest energy density of any primary cell: up to 710 Wh/Kg and 1420 Wh/I.

• Higher capacity… Tadiran cells feature the highest capacity by weight and volume compared to any known battery technology.

• Extended temperature range… Tadiran batteries can operate in temperatures ranging from -80°C to +125°C. However, to maximize the capacity, standard cylindrical wafer type cells are rated to a maximum temperature of +85°C. Specially modified high and low temperature cells are also available.

• Higher operating voltage…Tadiran lithium thionyl chloride cells have an open circuit voltage of 3.67V and an operating voltage of up to 3.6V, a considerably higher voltage than almost any other primary cell.

• Patented safety features…Tadiran lithium thionyl chloride cells offer unmatched safety due to their unique “failsafe” construction.

• Environmentally friendly…these batteries are free of heavy metals, making them among the most environmentally friendly of all batteries.
