The name "button cell" comes from how a button cell looks. It is a single-cell battery that is frequently used to power tiny gadgets like watches and hearing aids. Its height measures between 1 and 6 mm (0.039 to 0.236 inches), while its diameter spans from 5 to 25 mm (0.197 to 0.984 inches). Two terminals are on the battery:
The durability of button cells is well known. Because of their low self-discharge, they can maintain their charge for a very long time (particularly when inactive).

The LR44 battery is an Alkaline Zinc Manganese button cell battery. The LR44 battery is typically a 1.5 Volt with an operating temperature ranging from 0°C- 60°C, while the optimal temperature is 20°C.
The SR44 battery is a silver oxide button cell featured in several well-known brand-name timepieces. The SR44 battery can also be used to power handheld calculators and other small devices. LR44, AG13, SG13, 357, and a few other cells are direct SR44 battery counterparts
The LR44 and SR44 are both button-cell batteries, which are small, cylindrical batteries typically used in small electronic devices such as calculators, remote controls, and digital cameras. The main difference between the two is their voltage. LR44 batteries have a voltage of 1.5V, while SR44 batteries have a voltage of 1.55V. Additionally, LR44 batteries are typically alkaline, while SR44 batteries can be either silver oxide or lithium. It's important to note that while LR44 and SR44 batteries may fit into the same device, they are not interchangeable and should not be used interchangeably as it could cause damage to the device or the battery.

A CR2032 battery is a non-rechargeable (primary) lithium coin or “button” cell battery that is 20mm in diameter x 3.2mm in thickness. The CR2032 battery has a voltage of 3 volts and a capacity of up to 240mAh, depending on manufacturer specifications. The CR2032 is the most common lithium coin cell battery currently used. Commercial uses of the CR2032 battery range from car key fobs and motherboards to security system panels and weapons sighting systems.
CR2032 is a lithium battery “coin cell”. LR44 is an alkaline battery “button cell”. The CR2032 is used as the battery in clocks, timers, and the clock circuit of a computer and if unused lasts 5 to 10 years. An LR44 is used in multimeters, led blinky lights, toys. LR44s may corrode after some time of non-use (if they still have capacity left) so you have to keep a close watch on them. They are not sealed as well as the CR2032 and do not last as long in storage. CR2032 is a very popular lithium 3.0V non-rechargeable 20x3. 2 mm battery, while the LR44 battery is a 1.5V alkaline non-rechargeable 11.6x5.

LR44 and A76 are all alkaline button batteries. 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 for one thing, the shelf life of LR44 with 5 years is longer than the shelf life of A76 with 3 years.
LR44 Features
High-cost performance has been achieved owing to the use of manganese dioxide as a cathode material.
Stable voltage output is available during the high-drain pulse discharge.
Murata-unique sealing structure, coupled with special sealing-material treatment, has helped accomplish excellent leakage resistance.
A76 Features
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.
