Energizer LR44/A76 Alkaline Button Cell Batteries (12 Pack)

The Energizer LR44/A76 is a 1.5V alkaline button cell battery sold in a 12-pack, designed for compact electronics that use AG13/LR1154/357 equivalents. Each cell measures 11.6mm diameter by 5.4mm height and delivers consistent voltage across its discharge cycle, making it suitable for watches, calculators, laser pointers, digital thermometers, remote controls, keyless entry fobs and medical glucose monitors.

Alkaline chemistry provides higher capacity than older zinc-carbon button cells, extending replacement intervals in low-to-moderate drain devices. The LR44 designation follows IEC standards, while A76 is the ANSI equivalent — both refer to the same battery. These cells work across a typical operating temperature range of -10°C to 50°C, covering most indoor and outdoor use cases except extreme cold environments.

Energizer constructs these button cells with leak-resistant seals to protect device circuits from corrosion damage during storage and normal use. The cells are manufactured without added mercury or cadmium, meeting current environmental standards for consumer alkaline batteries. Each cell provides approximately 110-150 mAh capacity depending on discharge rate, with higher capacity in low-drain applications like watches and lower capacity in high-drain uses like continuous LED illumination.

The 12-pack format suits households and workplaces that maintain stock for multiple devices, or commercial users who replace batteries in batches. Cells have a shelf life of approximately 3-5 years when stored at room temperature, retaining around 80% of initial capacity at end of shelf life. Use-by dates are printed on the packaging.

What devices use LR44/A76 batteries?

Common applications include wristwatches, pocket calculators, laser pointers, digital thermometers, car key fobs, small LED torches, glucose meters, and some children's toys. Check your device manual or the battery compartment for markings — LR44, A76, AG13, LR1154, 357, and 303 all refer to compatible button cells with the same 11.6mm x 5.4mm dimensions and 1.5V output.

Are these rechargeable?

No. LR44/A76 alkaline button cells are single-use and should be recycled after discharge. Attempting to recharge alkaline cells can cause leakage or rupture. For rechargeable button cell applications, look for nickel-metal hydride (NiMH) or lithium rechargeable alternatives where compatible.

How long do they last?

Runtime depends on device drain. In a quartz watch drawing 1-3 microamps, a single LR44 typically lasts 1-3 years. In a laser pointer or LED torch drawing 10-50 milliamps continuously, expect 2-15 hours. Devices with intermittent use fall between these extremes.

Can I mix old and new batteries?

Avoid mixing batteries of different ages or charge states in multi-cell devices. The weaker cell will limit total output and may reverse-charge as the stronger cells discharge, reducing lifespan and increasing leakage risk. Replace all cells in a device together.
