Sony Alkaline AM4 AAA/LR03 1.5V Battery — Blister Pack of 2 Cells (1 Pair)

This is a pair of Sony-branded AAA alkaline pencil batteries in a sealed blister pack, the slim size that powers the small everyday things: television and air-conditioner remotes, calculators, wall clocks, cameras, keyless entry fobs and children's toys. Each is a 1.5V alkaline primary cell using zinc and manganese dioxide chemistry, carrying the LR03 and AM4 designations as well as the common AAA name. A cell measures 44.2mm long and 10.28mm in diameter and weighs around 8g, matching the standard AAA footprint exactly, so it seats properly in any compartment marked for that size. Unused cells keep their charge for roughly 8 years, which is why a spare pack is worth putting in a drawer rather than buying one at a time. They are disposable primary cells, not rechargeable. AAA is the size that runs out at the worst possible moment: the remote during a match, the calculator before an exam, the clock that quietly stops overnight. Buying a pair keeps a fresh set within reach without leaving cells sitting unused for years. They are best suited to the steady, low-drain work these devices ask for, and the leak-resistant alkaline build means a set left in a rarely used remote or a desk drawer through a humid summer is not going to ruin the contacts.
