what is the difference between lr43 and lr44 batteries

LR43 and LR44 batteries are both small button cell batteries commonly used in small electronic devices such as calculators, watches, and medical devices. The key difference between the two is their size and voltage. LR43 batteries are also known as AG12 or 386A batteries and have a diameter of 11.6 mm and a height of 4.2 mm. They typically have a voltage of 1.5V, making them suitable for low-drain devices. On the other hand, LR44 batteries, also known as AG13 or 357A batteries, have a slightly larger diameter of 11.6 mm and a height of 5.4 mm. They also have a higher voltage of 1.5V, making them suitable for devices that require more power. When choosing between LR43 and LR44 batteries, it's important to consider the specific requirements of your device in terms of size and power. Both types of batteries offer reliable performance and long-lasting power for your small electronic devices.
