## Long description

Camelion SR66W-377 is a 1.5V alkaline button cell designed for small electronic devices such as wristwatches, calculators and select medical instruments. The mercury-free chemistry offers stable voltage output and predictable shelf life. Its compact, standardized diameter and thickness make it suitable as a direct replacement for devices that specify the SR66W or 377 format, providing reliable power in a low-drain form factor.
Advantages
The alkaline composition ensures consistent nominal voltage and a low self-discharge rate, which helps preserve capacity during storage. Being mercury-free reduces environmental impact and complies with modern safety requirements for consumer batteries. The cell's standardized dimensions enable broad compatibility with many watch and small-electronics models, and its sealed design minimizes leakage risk under normal operating conditions.
Suitable for
 Wristwatches and small timepieces
 Calculators and handheld electronic calculators
 Small medical devices with compatible battery form factor
 Remote controls and key fobs designed for button cells
 Low-drain sensors, clocks and measurement instruments

How to use
Replace the depleted button cell with the Camelion SR66W-377 by opening the battery compartment of the device according to the manufacturer's instructions. Observe polarity when inserting the cell: the positive side is the flat top and the negative side contacts the casing or spring terminal. Ensure the battery sits flush in the compartment and close the cover securely. Dispose of the used battery according to local regulations for battery recycling.
Usage recommendations
Store unused batteries in a cool, dry place away from direct sunlight and metallic objects. Do not attempt to recharge, short-circuit, disassemble or expose the battery to heat or fire. For devices sensitive to voltage stability, check device manufacturer guidance to confirm compatibility with alkaline button cells designated SR66W or 377.
