Twelve 3.6V 1/2 AA lithium button-top cells in a pack

Xeno Energy

Xeno Energy XL-050H 3.6V 1/2 AA 850mAh Lithium Battery 12-Pack

SKU CH-8ANF-K1ACH

Twelve 3.6V 1/2 AA lithium cells deliver 850mAh each with a 10+ year shelf life and sub-1% annual self-discharge

  • Battery type1/2 AA Lithium
  • Reliable power for a decade with 10+ year shelf life
  • Stable 3.6V output maintained across most of the battery lifetime
  • Ready for extreme conditions from -55°C to +130°C
  • Minimal self-discharge under 1% per year at 20°C
  • Twelve 1/2 AA cells deliver 850mAh each for long runtime

Industrial power source

This 12-pack of Xeno Energy XL-050H lithium cells delivers 3.6 volt output with .8 ampere-hour capacity in the 1/2 AA form factor. The button-top termination suits equipment requiring a positive contact protrusion. Designed for professional and industrial devices that demand long-term, low-current reliability rather than high-drain consumer use.

Current and temperature limits

Maximum recommended continuous current is 10 milliamperes, restricting use to low-power applications such as memory backup, utility metering or remote sensors. The chemistry operates from -55°C to +130°C and retains over 99 percent capacity after one year at +20°C. The non-flammable inorganic electrolyte is corrosive, so the cells must never be punctured, incinerated or exposed to fire.

Simple drop-in replacement

Installation consists of matching polarity and inserting the cells into the battery compartment or holder; no soldering or configuration is required. Common errors include attempting to recharge these primary cells, exceeding the 10 milliampere continuous limit or using them in high-drain devices that cause premature voltage drop. Always verify the equipment specifies 3.6 volt lithium 1/2 AA chemistry before fitting.

Questions about this item

Should I buy the 12-pack or look for a different quantity?

The product is supplied as a 12-pack of 1/2 AA lithium cells, each rated at 3.6 V and 850 mAh. If your device uses one or two cells, the pack provides spares; for larger installations it may cover the full requirement.

What does the 850 mAh rating mean for actual runtime in my device?

At the maximum recommended continuous current of 10 mA, a single cell can deliver its rated capacity for roughly 85 hours; lower drain extends runtime proportionally, while higher pulse loads reduce it.

Are these batteries compatible with the 14250 size standard used in my meter?

Yes — the XL-050H matches the 14250 form factor (14.5 mm diameter, 25.2 mm height) and is listed as compatible with Saft LS-14250, Tadiran TL-5101 and other 14250-type cells.
