Single AA lithium cell for low-drain devices

The Ultralast LAA is a single AA-size primary lithium cell rated at 2450mAh and 3.6V. It suits equipment that requires the higher voltage of lithium chemistry rather than standard alkaline or NiMH alternatives. The LS14500 form factor fits devices designed for this specific size.

Stable voltage with minimal self-discharge

Lithium primary chemistry delivers a flat discharge curve and very low self-discharge during storage. The cell produces no audible noise and generates negligible heat in normal low-current applications. No charging circuit or external power supply is involved because the battery is non-rechargeable.

No bundled accessories or software included

The package contains only the single 14500 cell; no holder, adapter or management software is supplied. Users needing multi-cell packs or integrated protection circuits must source those separately. The cell is not intended for rechargeable applications or high-drain loads.

Questions about this item

How do I install the Ultralast LAA AA lithium battery and what polarity mistake should I avoid?

Insert the single AA cell with the positive tip toward the device's + contact and the flat end to −; reversing the 3.6V lithium cell can damage sensitive electronics.

What replacement will the Ultralast LAA primary lithium battery need after it is depleted?

The 2450mAh LS14500 cell is non-rechargeable; once exhausted you must swap in a fresh 3.6V AA lithium primary battery.

At what voltage does the Ultralast LAA 3.6V lithium cell hit its usable limit under continuous load?

The 3.6V primary lithium chemistry maintains output until capacity is spent, then voltage drops sharply below the device's cut-off threshold.
