LR44 Cell Button Battery

An LR44 button battery is a small, coin-shaped lithium battery commonly used in small electronic devices. It's 11.6mm in diameter and 5.4mm thick, with a voltage of 1.5V. These batteries are popular in watches, calculators, medical devices, and small toys. They're known for their long shelf life and reliable performance in low-drain devices.

Not all LR44 batteries are identical. While they share the same size and voltage, there can be differences in quality, capacity, and performance between brands. Some manufacturers produce higher quality LR44s with longer lifespans or better performance in specific conditions. It's important to choose a reputable brand for optimal device performance and safety.

The lifespan of an LR44 battery depends on its usage and the device it powers. In low-drain devices like watches, they can last 1-2 years. In high-drain devices like laser pointers, they may only last a few hours of continuous use. Factors affecting battery life include temperature, device power consumption, and battery quality. Proper storage can extend shelf life up to 5-10 years.

In the UK, the LR44 battery is often referred to as an AG13 or 357. These designations are interchangeable and refer to the same type of battery. When shopping in the UK, you may see batteries labeled as AG13 or 357 instead of LR44. They have the same specifications and can be used as direct replacements for LR44 batteries in most devices.

While both are button cell batteries, LR44 and CR2032 are not interchangeable. LR44 batteries are 1.5V, while CR2032 are 3V. They also differ in size: LR44 is smaller and thinner. Using a CR2032 in place of an LR44 could damage your device or cause malfunction. Always use the battery type specified by the device manufacturer.

Proper disposal of LR44 batteries is crucial for environmental safety. Don't throw them in regular trash. Many electronics stores, supermarkets, and recycling centers offer battery recycling services. Before disposal, tape the battery terminals to prevent short circuits. Some areas have specific regulations for battery disposal, so check local guidelines for proper recycling methods.

LR44 batteries power a wide range of small electronic devices. Common items include digital watches, calculators, car key fobs, glucose meters, laser pointers, small LED lights, and children's toys. They're also used in some medical devices like thermometers and hearing aids. Always check your device's manual to confirm the correct battery type before replacement.

Signs that your LR44 battery needs replacement include: device performance slowing down, dimming display or lights, unexpected shutoffs, or complete device failure. In watches, you might notice the second hand jumping in 4-second intervals. For critical devices like medical equipment, consider preventive replacement based on the manufacturer's recommendations to ensure uninterrupted operation.

While rare, LR44 batteries can leak or rupture if damaged, exposed to extreme temperatures, or left in devices for extended periods. To prevent this, remove batteries from devices not in use, avoid mixing old and new batteries, and store them in a cool, dry place. If a battery does leak, carefully clean the device with a cloth and vinegar solution, avoiding skin contact with the leakage.

Rechargeable alternatives to LR44 batteries exist, typically labeled as LR44R or AG13R. However, these are less common and may not be suitable for all devices. Rechargeable versions usually have a slightly lower voltage (1.2V vs 1.5V) which can affect device performance. Before using rechargeable alternatives, check your device's compatibility to ensure proper function.
