• The LR44 is a zinc-manganese alkaline button cell battery. The LR44 battery is normally 1.5 volts and can operate at temperatures ranging from 0 to 60 degrees Celsius, with 20 degrees Celsius being the ideal range. 
• The LR44 battery can be found in a range of devices, including watches, motherboards, and medical devices such as thermometers. A76, AG13, L1154, LR1154, 157 are all examples of LR44 battery equivalents. These sizes can be used to replace LR44 batteries. Other batteries that are comparable to the LR44 battery but have a different chemistry composition are also available. 
• The LR44 battery has the same size as silver oxide button cells such the SR44, SR44SW, 303, and 357, but it has a different chemistry. 
• Despite the fact that batteries can easily fit into each other's gadgets, it is critical to select the suitable battery type for your device to avoid over/under discharge. To avoid any complications that could damage your device, double-check the size and voltage of the battery you require.

• Energizer A76 Batteries give your vital devices a steady supply of power. These little batteries work with a wide range of devices, including keyless entry systems, heart rate monitors, and diabetes monitors. 
• When you need replacement calculator batteries or fresh batteries for watches, toys, or games, look for these compact batteries. 
• These micro alkaline button batteries, which are similar in size to silver oxide batteries, contain no mercury and hence have a lower environmental impact. Energizer, the world's most popular specialized battery brand, will keep your devices powered up for a long time.

LR44 Features
• Excellent cost performance
High-cost performance has been achieved owing to the use of manganese dioxide as a cathode material.
• Excellent stable discharge and high-drain pulse discharge characteristics
Stable voltage output is available during the high-drain pulse discharge.
• Excellent leakage resistance
Murata-unique sealing structure, coupled with special sealing-material treatment, has helped accomplish excellent leakage resistance.

• A76 is a manganese dioxide chemistry coin-cell battery.
• This alkaline battery is perfect for memory backup and high-pulse-rate electronic applications.
• The Energizer A76 Manganese Dioxide Battery is a cost-effective power source for applications where a discharge curve isn't required.

Conclusion of LR44 VS A76

Duracell 76A, Energizer A76, and AG13 batteries are direct LR44 replacements. These batteries are perfect replicas of the LR44 battery, with the exception of the name. All of these batteries are interchangeable. LR44 is the Equivalent of A76. But except one thing, the shelf life of LR44 with 5 years is longer than the shelf life of A76 with 3 years.
