Renata 389 / SR54 Silver Oxide Button Battery 5-Pack

5-Pack Silver Oxide Button Cells

This Renata 5-pack supplies five 389 / SR54 silver-oxide button batteries rated at 1.55 volts each. They are suited for watches, calculators, medical devices and other compact electronics that require a stable voltage output. The silver-oxide chemistry delivers a flatter discharge curve than alkaline alternatives. Each cell measures 11.6 mm in diameter and 3.1 mm in height.

Capacity and Headroom

Silver-oxide chemistry typically lasts up to five times longer than alkaline LR54 or LR1130 equivalents in the same low-drain applications. The 1.55 V nominal voltage remains steady through most of the service life, reducing the risk of early cut-off in voltage-sensitive circuits. In high-drain or continuous-load scenarios the capacity advantage narrows and the cells will deplete faster than their rated shelf life suggests.

Interface and Compatibility Limits

The 11.6 mm x 3.1 mm form factor fits any holder designed for the 389 / SR54 / 189 / SR1130 / LR1130 series, including cross-references such as GP389, V389, D389, SR1130W, GP189, S1131E, L1131, G10, V10GA, RW89, 626, M Battery, SB-BU and 280-15. Devices requiring a different diameter, height or voltage — such as 1.5 V alkaline-only compartments or larger coin cells — cannot use these batteries.
