Tadiran

Tadiran TL-2200/S 3.6V C 7.2 Ah Lithium Battery

SKU CH-Q6J0-ETAY4

A 3.6 V C-size lithium thionyl chloride cell delivering 7.2 Ah with a ten-year shelf life and operation from -60 °C to +85 °C

  • Battery type26500
  • High 3.6 V voltage stays stable through most of the service life
  • 2 Ah capacity ranks among the highest available for this size
  • Shelf life exceeds 10 years with under 1 % yearly self-discharge
  • Operates reliably from -60 °C to +85 °C in humid conditions
  • Button-top 26500 format fits ER26500, LS26500 and compatible models

Primary Power for Long-Life Devices

The Tadiran TL-2200/S is a 3.6V C-size lithium thionyl chloride battery rated at 7.2 Ah. It suits meters, trackers, alarms and other industrial electronics that need a single primary cell with a 10+ year shelf life and a low self-discharge rate below one percent per year at 20°C.

Steady Output Across Extreme Temperatures

The cell delivers a maximum recommended continuous current of 230 mA and can supply pulse currents up to 400 mA. High operating voltage remains stable for most of the application lifetime across an operating range of -60°C to +85°C, and the non-flammable inorganic electrolyte resists humid environments.

Simple Button-Top Fit With Safety Limits

A 26 mm diameter by 50 mm height button-top termination fits standard C-size holders for compatible models such as ER26500 and LS26500. The battery is not rechargeable; do not attempt recharging. Store in a clean, cool, dry area not exceeding 30°C and avoid mixing different models in series.

Questions about this item

How much heat does the 3.6 V 7.2 Ah lithium cell generate during continuous 230 mA discharge?

The chemistry runs at high operating voltage with stable output across its lifetime; self-discharge is below 1 % per year at 20 °C, so internal heating under the rated 230 mA continuous load is minimal.

What holder or contacts are required for the button-top termination on this C-size cell?

The 26 mm diameter by 50 mm height button-top cell fits standard C-size battery holders or spring contacts that accept the ER26500/LS26500 form factor.

Can the TL-2200/S be combined in series with older ER26500 or LS26500 cells already in my device?

Do not mix different models in series; the supplier explicitly warns against using different battery models together in a series string.
