Energizer 357/303 Silver Oxide Battery - 1.55V

Energizer 357/303 Silver Oxide Multi-Drain Battery is a compact 1.55-volt button cell intended for compatible precision electronics. The 357/303 designation covers applications that may require either high-drain or low-drain performance, making this silver-oxide cell suitable for many devices that specifically list 357, 303, SR44, SR44W, SR44SW, or an approved equivalent in their instructions.

Silver-oxide chemistry is valued for a stable operating voltage and reliable performance in small electronic equipment. In a bicycle shop, this format may appear in certain computers, sensors, measuring tools, shop instruments, remotes, or older accessories. Compatibility must be confirmed by battery number rather than appearance alone. Similar-size alkaline cells such as LR44 or A76 can differ in discharge characteristics, so follow the equipment manufacturer’s recommendation when accuracy or runtime matters.

Before installation, note the polarity of the old cell and clean the compartment if needed. Handle the new battery by its edge, place the positive and negative faces in the orientation shown by the device, and make sure the cover closes without force. If equipment uses multiple cells, replace the complete set together and do not mix old batteries with new ones.

This listing is for one Energizer 357/303 battery in retail packaging. Keep button batteries away from children and pets because swallowing can cause severe injury. Secure every battery compartment, isolate used cells from metal objects, and take depleted silver-oxide batteries to a suitable recycling or household hazardous-waste collection location.

Its compact retail package also makes it convenient to organize within a shop battery display.
