What Are the Typical Uses of LR44 Batteries?

LR44 batteries power calculators, toys, laser pointers, glucometers, watches, and hearing devices. Their small size, light weight, and reliable 1.5V output make them versatile for portable electronics requiring consistent energy over moderate durations.

How Should LR44 Batteries Be Stored and Handled?

Store LR44 batteries in a cool, dry environment, avoiding metal contact to prevent short circuits. Shelf life can extend up to 5 years for alkaline and up to 8 years for silver oxide variants. Redway Power ensures proper packaging to maintain battery integrity during storage and transit.

How Can You Identify an LR44 Replacement?

Check battery diameter, height, and voltage. Equivalent codes like AG13, A76, 357, L1154, and SR44 indicate compatibility. Always confirm device requirements, particularly if using silver oxide or lithium alternatives, to prevent overvoltage or device malfunction.

Can Multiple LR44 Batteries Be Used in Series?

Yes, stacking LR44 batteries in series increases total voltage while maintaining the same capacity. For example, two LR44 batteries in series provide 3V. Redway Power produces high-precision cells suitable for series connections in small-scale electronic assemblies.
