What it fits

Long-life sensors, beacons, and industrial electronics. 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 CR2477 is about 24.5 mm across and 7.7 mm thick.
