LR1130

1.5V alkaline button cell

LR1130 is an 11.6 × 3.1 mm alkaline button cell. AG10, LR54 and 189 are common pack labels. Casio MS-20YC and SL-310YC use one LR54/LR1130 as the Two-Way Power backup cell (solar + button battery). SR1130 is the silver-oxide size twin — see SR1130 vs LR1130. LR44 shares the diameter but is much thicker — see LR1130 vs LR44. Solar-only models such as fx-260 SOLAR II have no replaceable LR1130.
