For Panasonic, Maxell, Mallory, GP and Sony, the equivalent for an L1154F battery carries the designation of LR44. Eveready, Energizer, Philips, UCAR, Sony and EXELL sell an equivalent battery labelled A76. Duracell also makes an equivalent battery marked PX76A or 76A.
An L1154F battery is a small alkaline 1.5-volt button cell, commonly used in LED flashlights, laser pointers, multimeters, watches, calculators and other small electrical devices. Similar-looking batteries are the MR44 mercury cell, the zinc-air PR44 and the silver-oxide SR44. While these batteries are the same size as the LR44, they are not always interchangeable as the nominal voltage is different in each.
