LR54 / LR1130 battery equivalent

What it fits
Toys and small electronics. Prefer 389/390 silver oxide in watches.. Confirm the printed number or measure the old cell before you buy — a 0.5 mm height difference will not seat correctly.
IEC names encode chemistry and size. SR is silver oxide, LR is alkaline, and CR is 3 V lithium. The digits are diameter and height in tenths of a millimeter, so LR1130 is about 11.6 mm across and 3 mm thick.
Same size, different chemistry
These fit the same cavity but are not true equivalents. Voltage and discharge curve differ — do not use them as a silent swap in a quartz watch.
