The Duracell 303/357 is a single-use silver-oxide (SR44) button cell engineered to provide stable 1.5 V output for small electronic devices. Supplied as a pack of 2, this compact coin battery is intended for precision-powered instruments where consistent voltage and long shelf life matter. Its chemistry and construction reduce voltage drop under light to moderate loads, making it suitable for devices that require steady performance over extended periods.
This single-use battery delivers predictable voltage and reliable operation in compact form factor devices. The silver-oxide chemistry offers higher capacity and better voltage stability compared with alkaline button cells of similar size, which helps maintain device accuracy. A long storage life enables the battery to remain ready for use when needed, and the small dimensions make it easy to install in recessed battery compartments.
Ensure the device is switched off or in a safe state before replacing the battery. Observe polarity markings in the battery compartment and insert the coin cell with the correct orientation. Press the cover or holder back into place until it is secure. For devices with sealed compartments, follow manufacturer instructions to avoid damage. Dispose of spent batteries according to local regulations for battery recycling.
Store unused batteries in a cool, dry place away from metal objects that could short the terminals. Do not attempt to recharge single-use silver-oxide cells. Replace all batteries in a device at the same time and avoid mixing old and new cells to maintain performance and prevent leakage.
