is sr44 the same as lr44

Yes, the SR44 and LR44 are essentially the same type of battery. They both belong to the same series of alkaline button cell batteries and share the same 11.6mm diameter and 5.4mm height. The main difference between the two lies in the chemical composition of the battery. The SR44, also known as the silver oxide battery, uses silver oxide as the cathode material, providing a more stable voltage output over time. On the other hand, the LR44, also known as the alkaline battery, uses alkaline manganese dioxide as the cathode material. Both the SR44 and LR44 are widely used in small electronic devices such as calculators, watches, cameras, and medical devices. They provide reliable power for these devices and have a long shelf life. These batteries are also widely available and affordable, making them a popular choice for consumers. Whether you need an SR44 or an LR44, you can trust in their quality and performance for your electronic devices.
