Listings indicate photo-focused 3V lithium batteries can hold usable power for up to 10 years in storage.
Listings typically use a 'Rechargeable' field: disposable lithium cells are labeled 'Single-Use' and rechargeable packs are labeled 'Rechargeable.'
These 3V cells are also listed for use in flashlights, smart‑home devices, calculators and tablet PCs, and small household or medical electronics such as key fobs, remote controls, glucose monitors, and thermometers.
Some coin-cell listings describe a non‑toxic bitter coating to discourage swallowing and child‑secure packaging that is difficult to open by hand.
