  • Compact 6.8 mm x 2.1 mm size fits slim compartments
  • Direct replacement for SR621SW, 364 and LR60 equivalents
  • Swiss-made Renata quality for consistent performance

Everyday power for small devices

This pack contains five Renata 364 silver oxide button cells, each delivering 1.55 volts in a 6.8 mm by 2.1 mm form factor. They suit watches, calculators, medical instruments and similar low-drain electronics that require a 364 or SR621SW size. The chemistry provides a flat discharge curve for consistent performance. Buyers needing rechargeable cells or larger capacities should choose a different product.

Steady voltage through the full cycle

Silver oxide chemistry maintains a stable 1.55 volt output from start to finish, avoiding the voltage sag common with alkaline equivalents during sustained use. Each cell supports continuous low-current draw without rapid fade. The five-piece pack lets you replace multiple devices or keep spares on hand. Devices that demand high pulse currents or rechargeable operation are not served by these cells.

Cool, silent operation with minimal draw

These button cells generate no perceptible heat or noise during normal operation because their internal resistance is very low at microamp loads. Self-discharge is minimal, so stored spares retain charge for years. No external power supply, cooling or ventilation is ever required. Applications needing user-replaceable rechargeable packs or higher energy density will not match this format.

Questions about this item

How much heat or noise does the 364 silver-oxide cell produce during continuous use?

Silver-oxide chemistry generates no audible noise and negligible heat at the 1.55 V output; the cell simply delivers steady voltage until depleted.

What device or holder must I already have to use these 6.8 mm × 2.1 mm button cells?

You need equipment with a 364 / SR621SW compartment — watches, calculators, medical sensors or any device specifying this 6.8 mm diameter by 2.1 mm height size.

Will the 364 pack work in older gear that lists equivalents such as SR621W, 364A or V364?

Yes — the supplier lists SR621W, 364A, V364 and over twenty other codes as direct equivalents, so legacy devices calling for any of those will accept these cells.
