Philips Ultra Alkaline AA LR6 Battery, 2-Pack

Philips Ultra Alkaline AA is a 1.5V alkaline battery in the standard LR6 size, supplied as a pair. It is a single-use cell for the everyday electronics around a home or office that expect an ordinary pencil battery. Philips rates the Ultra Alkaline line at 132% more power than the industry standard, and the cells use a leak-resistant construction, which matters in a device that sits untouched for months at a time. Shelf life is up to 10 years, so a spare pair bought now is still usable long after the pack goes into a drawer. AA cells of this type run remotes, wireless mice and keyboards, small lights, wall clocks and desk instruments. Because they are not rechargeable, the practical approach is to keep a pack in the drawer and change both cells together rather than mixing a fresh cell with a tired one, which is what usually shortens the life of a set. For a device in constant daily use a rechargeable cell suits better; for the remote and the clock, an alkaline pair fitted and forgotten is the simpler answer.
