Energizer AAAA/E96 1.5V Alkaline Battery – 1-Pair (2 Cells)

This is a pair of Energizer AAAA alkaline cells, the slim quadruple-A size that powers small precision devices rather than everyday household electronics. If a stylus pen, laser pointer, LED penlight, glucose monitor or compact remote has stopped responding, this is the cell it takes. Each cell is a button-top alkaline battery delivering 1.5V, with a capacity of around 595mAh — enough to keep a low-drain device running for a long stretch of normal use. They are single-use rather than rechargeable, and the pack holds 2 cells at a total weight of about 13g, so it takes up almost no room in a drawer, a pencil case or a laptop bag pocket. AAAA is an awkward size to find on short notice, which is why keeping a spare pair on hand is worth doing — an active stylus that dies mid-lecture or mid-meeting stops your work outright. Energizer's alkaline chemistry holds up well in storage, so a pair bought now stays ready for whichever device needs it next. Fit them the way the device diagram shows, and in equipment that takes two cells, replace both together so they discharge evenly.
