1/2 AA Lithium 850mAh 8-Pack
This 8-pack of Xeno Energy XL-050H cells delivers 3.6 volts and 850mAh capacity in the 1/2 AA form factor. The lithium chemistry provides a shelf life exceeding 10 years with less than 1% annual self-discharge at 20°C. They suit meters, sensors, memory backup and other low-drain devices that require long-term, maintenance-free power. The button-top termination ensures a secure contact in standard holders.
Replaces Tadiran Saft Sonnenschein
These batteries are direct replacements for Tadiran TL-4902, TL-2150, TL-5101, TL-5111, TL-5151, TL-5902, Saft LS-14250 and LS-14250c, Sonnenschein SL-350/S, SL-750/S, SL-150/S and Toshiba ER3v cells. The jump is worth it when existing primaries have dropped below usable voltage or when a project demands the wide -55°C to +130°C operating range. They are not for designs needing rechargeable chemistry or continuous currents above 10 mA.
Simple Drop-In Install
Installation is a straightforward swap: remove the depleted cell and insert the new button-top battery observing the marked polarity. The 14.5 mm diameter and 25.2 mm height match the 1/2 AA standard, so no adapter or soldering is required. What usually goes wrong is reversing the polarity, attempting to recharge the non-rechargeable lithium chemistry, or specifying the cell for loads that exceed the 10 mA continuous rating.

Questions about this item
Will the 14.5 mm diameter and 25.2 mm height fit my 1/2 AA device?
Yes, the cells measure 14.5 mm across and 25.2 mm tall, matching the standard 1/2 AA form factor.
How do I install the button-top terminals correctly?
Align the raised positive button with the device's positive contact; the flat negative end goes against the spring or negative plate.
When should I replace the pack given the 10-year shelf life?
Replace after about ten years in storage at 20 °C, or sooner if the device shows voltage drop under load.
