  • Replaces 386, 301, SR43SW and many equivalent codes

Three-pack silver oxide cells

This pack contains three Renata silver oxide button batteries. Each cell delivers 1.55 Volt and measures 11.6 mm by 4.2 mm. The chemistry lasts five times longer than alkaline equivalents. Suitable for watches, calculators and small medical devices.

Direct drop-in replacement

The batteries match common designations such as 386, 301, SR43SW and LR43. Installation is a simple swap in the device’s battery compartment. Ensure the positive side faces the correct terminal. A loose fit or reversed polarity will prevent the device from powering on.

Steady 1.55 Volt output

Silver oxide chemistry holds voltage flat for most of the discharge curve. The three cells comfortably run quartz watches, digital thermometers and glucose meters for extended periods. High-drain devices such as LED lights or motorised toys will exhaust the capacity quickly.

Questions about this item

How can I verify the 1.55 Volt silver oxide cells are working after installation?

Use a multimeter to confirm each cell reads near 1.55 Volt under no load; the device should then power on and maintain steady operation.

What comes in the pack and do I need any extra items?

The pack contains three 386 / 301 / SR43SW silver oxide button cells measuring 11.6 mm x 4.2 mm; no additional accessories are required.

Which of the listed equivalent codes matches my device that takes a 301 or 386 cell?

All codes in the list — 301, 301A, 386, 386A, D386, V386, GP386, SR43, SR43W, SR43SW, LR43, G12, G12A, V12GA, 186, 186-1, L1142, LR1142, SR1142, S1142E, 260, RW84, GP86A, 1176A, 280-41, SB-B8, H Battery — refer to the same 11.6 mm x 4.2 mm 1.55 Volt silver oxide size, so any will fit.
