Button cell battery Duracell LR44 20-pack (alkaline) BUN0143A

Duracell LR44 button cell batteries in a 20-pack provide a reliable alkaline power source for small electronic devices that require LR44 (also known as A76 or AG13) cells. This multi-pack is designed to supply consistent voltage and long shelf life for everyday items such as calculators, toys, watches and some medical or measuring instruments. The compact coin shape and standard LR44 dimensions make these cells easy to install and replace in compatible devices.

Advantages

Duracell LR44 batteries offer steady voltage output during their useful life and are formulated for low-to-moderate drain devices. The alkaline chemistry ensures a longer shelf life compared with standard zinc-carbon cells, and the 20-pack quantity reduces the need for frequent purchases. Cells are individually sealed for safe storage and straightforward handling when replacing batteries in small devices.

Suitable for

• Calculators and small electronic desk devices
• Watches and small clocks
• Children’s toys and electronic games
• Portable medical devices and thermometers (where LR44 size is specified)
• Laser pointers, key fobs and small LED lights

How to use

Insert the LR44 cells into the battery compartment of the device following the polarity markings (+ and −) printed on the device or battery holder. Use a clean, dry environment when handling the batteries and avoid short-circuiting terminals. If replacing multiple cells in a device, replace all batteries at the same time to maintain consistent performance. Dispose of used alkaline batteries according to local regulations or recycling programs.

Usage recommendations

Store unopened cells in a cool, dry place away from direct heat or sunlight. Remove batteries from equipment if the device will be unused for an extended period to prevent leakage. Keep out of reach of children and seek immediate medical attention if a battery is swallowed.
