Silver Oxide Chemistry for Stable Voltage

These Renata button cells use silver oxide chemistry to deliver a steady 1.55 volt output across their lifespan. The 5-pack suits owners of watches, calculators, medical devices or small electronics that require the 394 or SR936SW size. Each cell measures 3.6 mm by 9.5 mm. Buyers needing lithium coin cells or rechargeable alternatives will not be served by this chemistry.

Low Self-Discharge in Normal Storage

Silver oxide construction keeps self-discharge low during typical shelf life, so spares remain ready when a device runs flat. No active cooling or power management is involved; the cells simply sit in a drawer or device until needed. Users who expect high-drain pulse performance or rapid recharge cycles should look elsewhere.

Five-Cell Pack Reduces Reorder Frequency

The box contains five identical batteries, letting you replace a dead cell immediately and keep the rest for future swaps. No software, adapters or charging hardware are bundled. Shoppers who want a single cell, a mixed-size assortment or a charger included will not find those here.

Questions about this item

How do I install the 394 silver oxide cell in my device, and what step do people often miss?

Insert the 394 cell with the flat positive side facing the contact marked +; the common mistake is placing the raised negative side against the positive terminal, which prevents the 1.55 V supply from reaching the circuit.

When will the 5-pack of SR936SW batteries need replacement?

Replace each 394 cell when the device shows low-power symptoms such as a dimming display or erratic operation; shelf life is several years if stored at room temperature in the original packaging.

What limit appears first during continuous use of a 394 button cell?

Voltage drops below the usable threshold as the silver oxide chemistry depletes, ending the 1.55 V output before any physical change to the 3.6 mm x 9.5 mm cell occurs.
