Five 1.55 V silver-oxide cells

This pack supplies five Renata 337 / SR416SW button batteries, each delivering 1.55 volts from a silver-oxide chemistry. The cells measure 1.6 mm by 4.8 mm and suit watches, calculators and small medical devices that require this exact footprint.

Direct replacement for 337, SR416SW and 623 codes

These batteries replace equivalents labelled 337, D337, GP337, V337, SR416, SR416SW, 623, 280-75 or SB-A5, so the upgrade is worthwhile when a device specifies any of those designations. They are not for applications needing higher capacity, rechargeable chemistry or a different voltage.

Questions about this item

What are the exact dimensions of the 337/SR416SW cells so I can verify they fit my watch case?

Each cell measures 1.6 mm thick by 4.8 mm in diameter, matching the standard 337/SR416SW footprint.

Insert each cell with the flat positive side facing the contact marked +; reversing them will prevent the device from powering on.
