Cylindrical 1/2 AA lithium battery with spot-welded tabs on both ends

Tadiran

Tadiran TLL-5902/T 3.6V 1/2 AA 1.1Ah iXtra Lithium Battery W/Tabs

SKU CH-Y0K3-YJFT6

A 3.6V 1/2 AA lithium thionyl chloride cell with spot-welded tabs delivers 1.1Ah capacity and operates from -60°C to +85°C

  • 6 V stable voltage for consistent device operation
  • 1 Ah capacity powers equipment longer between changes
  • 10+ year shelf life keeps spares ready when needed
  • 60 °C to +85 °C range works in extreme environments
  • Spot-welded tabs simplify secure PCB mounting

Power Source for Long-Life Devices

The Tadiran TLL-5902/T is a 3.6V 1/2 AA lithium thionyl chloride cell rated at 1.1 Ah. It suits equipment that needs a very low self-discharge rate and a stable voltage over years of unattended operation. Typical uses include utility meters, security sensors and industrial data loggers. The wide temperature range of -60°C to +85°C supports outdoor and harsh-environment installations.

Replaces Older Tadiran and Saft Cells

This iXtra series battery is compatible with Tadiran TL-4902, TL-2150, TL-5101, TL-5111 and TL-5902 models. It also cross-references to Saft LS-14250 and LS-14250c, Toshiba ER3v and Sonnenschein SL-350/S, SL-750/S and SL-150/S parts. The jump is worth it when an application demands the higher 1.1 Ah capacity or the 10+ year shelf life quoted for this chemistry. It does not suit designs that require rechargeable cells or continuous currents above 50 mA.

Simple Two-Tab Installation

Spot-welded tabs on both ends allow direct soldering to a PCB without a separate holder. Observe correct polarity and avoid excessive heat during soldering to prevent seal damage. The non-flammable, non-pressurised electrolyte improves safety, but the chemistry is corrosive if the case is breached. Do not attempt to recharge the cell under any circumstances. Buyers who need a rechargeable pack or a higher pulse current than 100 mA should select a different chemistry.

Questions about this item

What diameter and height clearance does the 14.5 mm by 25.2 mm cell need inside my device?

The cell measures 14.5 mm in diameter and 25.2 mm in height, so the compartment must accommodate those maximum dimensions.

How do I solder the spot-welded tabs without damaging the lithium thionyl chloride chemistry?

Use a temperature-controlled iron at the lowest effective heat, apply flux sparingly, and limit contact to under three seconds per tab to avoid overheating the electrolyte.

After 10 years of storage at 20 °C, how much capacity will the 1.1 Ah cell have lost?

Self-discharge is below 1 % per year, so after 10 years the cell retains virtually all of its 1.1 Ah rating.
