Xeno Energy XL-145F 3.6V 8.5Ah C Lithium Battery

SKU CH-33NS-3Y4YY

A 3.6 V C-size lithium primary cell delivering 8.5 Ah with a 150 mA continuous rating and a 10-plus-year shelf life

  • High 3.6 V operating voltage stays stable through most of the application lifetime
  • 5 Ah capacity is among the highest nominal capacities on the market today
  • 10+ year shelf life with less than 1 % capacity loss per year at +20 °C
  • Operates reliably from -55 °C to +85 °C in humid environments
  • Non-flammable, non-pressurised inorganic electrolyte with low magnetic signature

Primary cell for long-life devices

The Xeno XL-145F is a primary lithium battery rated at 3.6V and 8.5Ah in C size. It suits metering, security and industrial electronics that require a single high-capacity cell. The button-top termination allows direct fit into compatible holders. This item is not rechargeable and must not be recharged.

Thermal stability and power profile

The cell operates from -55°C to +85°C with a stable voltage through most of its life. Self-discharge stays below 1% per year at +20°C, supporting a shelf life beyond 10 years. Maximum continuous current is 150mA with pulse capability up to 230mA. The inorganic electrolyte is non-flammable at ambient temperature.

Cross-reference list for drop-in use

The datasheet lists compatibility with TL-4920, TL-5920, Saft LS26500C, ER26500 and several XL and SB models. This lets engineers replace those part numbers without redesign. The battery weighs 51g and uses a corrosive electrolyte; solder tabs quickly and avoid mangled casings. Do not mix different models in series.

Questions about this item

How do I install the XL-145F correctly and what step causes the most damage?

Insert the button-top cell with the positive end facing the contact; finish any tab soldering in a few seconds to avoid overheating the non-flammable electrolyte.

What maintenance or replacement will the XL-145F need over its service life?

The cell is non-rechargeable; expect a single replacement after the 10+ year shelf life or when voltage drops below the device cut-off.

At what sustained current does the XL-145F hit its limit first?

Continuous draw above 150 mA exceeds the maximum recommended rating; pulse loads above 230 mA also stress the chemistry.
