Jargon buster
Plain-language definitions for the technical terms used above.
- CR1225
- CR1225 is a specific size of 3 V lithium coin cell, about 12 mm in diameter and 2.5 mm thick. The code matters because a coin-cell holder only fits one size, and a cell's capacity affects how long any device it powers can run before the battery needs replacing.
