Varta Watch Battery - Silver - SR44 - 1.55V

This battery is primarily designed for miniature electronics, including analog and digital watches, fitness trackers, small calculators, digital thermometers, and other small electronic devices that require a 1.55V SR44 silver-oxide button cell.

While often interchangeable in size, SR44 batteries use silver-oxide chemistry providing a stable 1.55V, whereas LR44 batteries use alkaline chemistry with a nominal voltage of 1.5V that drops more significantly over its discharge cycle. The Varta -V303 is an SR44 type.

Battery life varies greatly depending on the device's power consumption. However, due to its silver-oxide chemistry and 160mAh capacity, it is designed for long-lasting performance in low-drain applications like watches.

No, the Varta -V303 is a single-use (primary) battery and is not designed to be recharged.

SR44 is an industry standard designation for a button cell battery that uses silver-oxide chemistry and has specific dimensions. It is also known by other designations like 357 or RW 32.

Store unused batteries in their original packaging in a cool, dry place, away from direct sunlight and metal objects to prevent short circuits.

Used batteries should be disposed of responsibly according to your local electronic waste or battery recycling regulations. Avoid disposing of them in regular household trash.

Ensure the battery is inserted with the correct polarity (+/-). Check that the battery contacts inside the device are clean and making proper contact. Verify that the device's battery compartment is securely closed.

Confirm that the inserted battery is the correct type (Varta -V303, 1.55V SR44). If the battery is new, it may be faulty; try a new one. Ensure there is no debris obstructing the battery or its contacts.

Check if the device is compatible with a 1.55V silver-oxide battery, as higher voltage or different chemistry batteries might cause issues. Some devices have features that consume more power; consult the device manual. Ensure the battery compartment is sealed properly to prevent unintended power drain.
