SR1130

1.55V silver oxide button cell

SR1130 is a 1.55V silver-oxide button cell (about 11.6 × 3.1 mm). Packs often say 389 or 390. Sharp EL-8130 and Casio ML-860 each take two SR1130 (G-10) silver-oxide cells. LR1130 / AG10 fit the same size but are alkaline — see SR1130 vs LR1130.

Rechargeables are not equivalents

Do not substitute a rechargeable cell unless the device documentation explicitly allows it. Silver-oxide and lookalike chemistries are not interchangeable with rechargeables by size alone.

Size family

Edge thickness in the 11.6 mm family — thicker bar means thicker cell. Not to scale. Highlighted cell is this page.

Device-specific caveats

From manufacturer-backed notes on devices that use SR1130 — not generic advice.

  • Button cells are a choking hazard — keep new and used cells away from children.
