These are Duracell's 1.5V alkaline AAAA (LR61) cells, sold in a two-pack. AAAA is a slim battery used in a narrow set of devices: styluses such as the Microsoft Surface Pen, some glucometers, small LED flashlights, and certain headsets and medical tools. Few brands still make AAAA cells, so Duracell's main draw is availability and shelf life rather than performance. Owners report they work as expected and last reasonably well in low-drain devices; the common complaint is that they are harder to find and pricier per cell than ordinary AA or AAA batteries.

Owners mostly say the cells fit and work in styluses, glucometers and small flashlights, with decent life in low-drain use. Complaints center on the niche size being hard to find and expensive for what it is.
