Description

The Energizer 317 is a 1.55V silver oxide button cell battery measuring 5mm thick and 11.6mm diameter (size SR516SW), supplied in a 10-pack. Silver oxide chemistry provides stable voltage throughout the discharge cycle, making these cells suitable for precision devices including analogue watches, calculators, medical instruments and fitness trackers where consistent power delivery matters more than peak output.

Each cell weighs 1.3g and fits devices requiring 317, SR516SW or equivalent button cell formats. The silver oxide construction delivers higher energy density than alkaline equivalents of the same size, extending runtime between replacements in continuous-draw applications such as watch movements. The 10-pack format suits users maintaining multiple devices or keeping spares for watches and medical equipment where battery failure disrupts daily function.

Energizer rates these cells for a multi-year shelf life when stored at room temperature, allowing the 10-pack to be kept as drawer stock without degradation. The zinc anode and silver oxide cathode are sealed in a stainless steel casing with a leak-resistant crimp seal, reducing the risk of electrolyte escape in sensitive devices. The flat discharge curve maintains 1.5V+ for most of the cell's life before dropping sharply near depletion, giving clearer end-of-life indication than alkaline chemistry.

Frequently Asked

What devices use 317 batteries?

The 317 format (also SR516SW) is common in analogue wristwatches, small calculators, glucose meters, pedometers and some hearing aid models. Check your device manual or the existing battery for size confirmation before ordering.

How does silver oxide compare to alkaline button cells?

Silver oxide provides stable 1.55V output throughout discharge and higher energy density, giving longer runtime in precision devices. Alkaline button cells start at 1.5V but voltage drops gradually during use, which can affect timekeeping accuracy in watches.

How long do these batteries last in storage?

Energizer silver oxide cells have a typical shelf life of 3-5 years when stored at room temperature in original packaging. Avoid storing in high heat or humidity to preserve full capacity.

Are these rechargeable?

No. Silver oxide button cells are single-use primary cells and cannot be recharged. Attempting to recharge them may cause leakage or rupture.
