Five-Pack Silver Oxide Button Cells

This pack contains five Renata 357 / SR44W silver oxide button batteries rated at 1.55 Volt each. They are suited for watches, calculators, medical devices and other compact electronics that require a stable voltage curve. The 11.6 mm by 5.4 mm form factor fits standard SR44 compartments. Buyers who need rechargeable cells or higher capacity formats should look elsewhere.

Consistent Output and Long Shelf Life

Silver oxide chemistry delivers a flat discharge profile so devices keep accurate time or measurement until the cell is depleted. Each unit lasts up to five times longer than an alkaline LR44 equivalent under the same load. Self-discharge is low, so spares stay ready in a drawer for years. No special storage or charging equipment is required.

Broad Cross-Reference Compatibility

The cells match a long list of industry codes including 357, SR44W, SR44H, GPA76, AG13, LR44, 675A and many others printed on device manuals or old packaging. This reduces the risk of buying the wrong size when the original marking has faded. The blister pack keeps the five batteries organised and prevents accidental shorting during storage.

Questions about this item

How do I install the SR44W batteries in my device, and what step do people often get wrong?

Insert each 11.6 mm x 5.4 mm cell with the flat positive side facing the contact marked plus; the common mistake is reversing polarity because both sides look similar.

What maintenance or replacement will the 357 silver oxide pack need later?

Each 1.55 Volt cell is single-use; when voltage drops the device stops working, so keep a fresh 5-pack on hand for immediate replacement.

What limit appears first under sustained use of these button batteries?

The 1.55 Volt output holds steady until the silver oxide chemistry is depleted, then voltage falls sharply and the device shuts down.
