LR44 battery

LR44 is the IEC designation for an alkaline 1.5 volt button cell, commonly used in small LED flashlights, digital thermometers, calculators, calipers, watches, clocks, toys, vibrators, multimeters and laser pointers.
The battery nomenclature is defined by the International Electrotechnical Commission (IEC) in its 60086-3 standard (Primary batteries, part 3 Watch batteries). The letter ''L'' indicates the electrochemical system used: a zinc negative electrode, manganese dioxide depolarizer and positive electrode, and an alkaline electrolyte. R44 indicates a round cell 11.4±0.2 mm diameter and 5.2±0.2 mm height as defined by the IEC standard 60086.
Manufacturers have their own part numbers for IEC type LR44 batteries including:
* LR44, LR44G, LR44GD, LR44H
* LR1154, L1154, L1154C, L1154F, L1154G, L1154H
* 6135011748057 (NSN)
* 1166A (Part Number)
* AG13, A613, AG14, AG-14, G13A, G13-A
* 157, 303, 357
* A76, AG76, GDA76, GP76A, GPA7, GPA75, GPA76, GPS76A,
* 1128MP, 208-904, A-76, CA18, CA19, CR44, D76A, KA, KA76, MS76H, PX76A, PX675A, RPX675, RW82, SB-F9, V13GA
Other types of batteries are or were made in the R44 size. Formerly, mercury batteries were made as button cells (types MR44 and NR44). Zinc-air batteries type PR44 require air to work. Silver-oxide batteries type SR44 may provide extra capacity compared to LR44 types but have slightly different voltage characteristics. Performance of a device meant to use a silver-oxide battery may be degraded with substitution of alkaline types. Light meters designed to use mercury batteries will give false readings with substitution of LR44 alkaline types. Fortunately some manufacturers provide proper adapters to solve this problem.
Manufacturer's numbers for silver oxide R44 size cells include:
* SR44, SR44W, SR44SW
* 6135-99-651-3240 (NSN)
* SR1154
* 1107SO
* 1131SOP
* SG13
* S76
* EPX76 (Energizer)
* 303, 357 (D357H, V357)
