Renata 317 silver oxide

To choose correctly, start by checking the nominal voltage of 1.55 V and the coin-cell format that matches your watch. Typically, it’s around 9.5 mm in diameter and about 2.6 to 2.7 mm thick depending on the model. Then pick the packaging that suits your needs—for example, packs of 1, 5, or 10 pieces depending on whether you’re replacing one watch or several connected devices. This category covers batteries used in wristwatches and other small electronic devices, all new and silver oxide.

The most complex part is the combination of size (diameter and thickness) with voltage and the technology type. A 9.5 mm diameter and thickness around 2.6–2.7 mm determine the exact fit inside the watch case, while the silver oxide technology provides a long service life and higher resistance to leaks than other types. Understanding these parameters helps you avoid incompatible replacements and preserves your watch’s performance.

If you’re a casual user replacing one or two watches, choose a simple format and smaller packs (for example, 1 piece). If you’re a repair professional or collector managing multiple watches or small electronic devices, go for larger bundles (5 or 10 pieces) so you always have a compatible battery on hand and reduce downtime caused by replacements.

Keep them in their original packaging in a cool, dry place, away from heat and humidity. Avoid contact with metal objects and store them out of reach of children. Before use, check the expiration date shown on the packaging to ensure optimal performance and avoid premature degradation while in storage.

These silver oxide batteries offer stable performance and increased leak resistance, making them suitable for watches and certain sensitive small electronic devices. Look for products described as having a long service life and reliable performance under normal use conditions, while staying within the specified voltage and battery size for the device compartment.
