Duracell LR44 Alkaline Button Cell Batteries (2 Pack)

The Duracell LR44 is a 1.5V alkaline button cell battery supplied in a 2-pack blister. Each cell measures 11.6mm diameter by 5.4mm height, fitting devices that specify LR44, A76, V13GA or 76A batteries. The alkaline chemistry provides stable voltage across the discharge cycle, making these cells suitable for low to moderate drain devices including calculators, digital thermometers, small toys, watches and key fobs.

Designed for consumer electronics that use button cells rather than AA or AAA formats, the LR44 delivers consistent current to precision measurement devices, remote controls, digital calipers and LED torches. Duracell's Duralock Power Preserve technology gives these cells a 5-year in-storage guarantee when unopened, so they remain charged and ready for use in emergency backup applications or infrequently-used devices. The 2-pack format suits households and workshops that need spares without bulk-buying larger multipacks.

The LR44 is one of the most common button cell sizes in consumer electronics, sharing the same footprint as AG13, LR1154, 357 and SR44 silver oxide cells. The alkaline chemistry trades the higher capacity of silver oxide for a lower cost per cell, making it a practical choice for devices that cycle through batteries regularly. Each cell weighs approximately 2g and the blister pack dimensions of 84mm x 120mm x 6mm allow the batteries to be stored in drawers, toolkits or vehicle glove boxes.

What devices use LR44 batteries?

LR44 cells power calculators, digital thermometers, small LED torches, watches, key fobs, digital calipers, glucose meters, remote controls and children's toys. Any device specifying LR44, A76, V13GA, 76A, AG13, LR1154 or 357 will accept this battery.

Can LR44 replace SR44 silver oxide batteries?

LR44 alkaline and SR44 silver oxide share the same physical dimensions and both deliver 1.5V nominal voltage, so they are physically interchangeable. SR44 cells hold higher capacity and maintain voltage more consistently under load, making them better for precision devices like cameras and watches, while LR44 cells offer lower cost for less demanding applications.

How long do LR44 batteries last in storage?

Duracell's Duralock technology gives these cells a 5-year storage guarantee when kept in their original unopened blister pack at room temperature. Once installed in a device, runtime depends on the current draw — a calculator may run for years, while a continuously-lit LED torch may drain the cell in hours.

Are these batteries rechargeable?

No. LR44 alkaline cells are single-use and cannot be recharged. Attempting to recharge alkaline batteries can cause leakage, heat buildup and rupture.
