Alkaline batteries have a longer shelf life and a higher charge density than zinc-carbon batteries and are less harmful than traditional mercury cells. These cells are commonly used small electronic devices such as clocks and alarms. Energizer LR1 N cells are a straight swap for LR01, 2011, MN9100, N size, E90, 4001, KN/KN-2, AM5, UM5, 810 and 910A models. These single use micro alkaline batteries provide an inexpensive alternative to lithium cells and are a safer substitute for mercury batteries. Energizer LR1 N batteries are versatile cells, suitable for powering a wide range of consumer electronics.
