10-Pack Silver Oxide Button Cells

This 10-pack supplies Renata 321/SR616SW silver oxide button batteries rated at 1.55 Volt. Each cell measures 1.65 mm by 6.8 mm and fits devices specifying the 321, D321, GP321, RW32, SP321, V321, SR616SW, SR616, SR65, SB-AF/DF, 1174SO or 280-73 designations. The pack contains ten pieces for multi-device use.

Chemistry and voltage match

Silver oxide chemistry delivers a stable 1.55 Volt output required by compatible watches, calculators and small electronics. Buyers needing alkaline 1.5 Volt equivalents or lithium 3 Volt coin cells cannot use this pack. Devices that call for a different diameter or height will not accept these 6.8 mm diameter cells.

Questions about this item

How long will the 1.55 V output stay steady in a watch movement?

Silver-oxide chemistry holds 1.55 V almost flat until the cell is exhausted, so a watch keeps accurate time for the full service life.

What does the 6.8 mm diameter mean for fitting the battery?

The cell is 6.8 mm wide and 1.65 mm thick, matching the SR616SW/321 compartment used in many quartz watches and small devices.
