Battery cross-reference
Different brands print different codes on the same size. Find the code on your old battery in the middle column; the left column is the size to buy. This table restates Energizer's battery cross-reference guide.[1 · Oct 29, 2026]

Selected rows; Energizer's guide lists dozens of watch and hearing aid sizes too.[1 · Oct 29, 2026] Names in the first column are Energizer's cell sizes.
Three things the code doesn't tell you
- Chemistry can differ inside one size. An LR44 is alkaline at 1.5 V; an SR44 (357/303) is silver oxide at 1.55 V.[2 · Oct 29, 2026][3 · Oct 29, 2026] See LR44 equivalents.
- Coin cells with the same diameter aren't the same battery. CR2032, CR2025 and CR2016 are all 20 mm across but 3.2, 2.5 and 1.6 mm thick.[4 · Oct 29, 2026][5 · Oct 29, 2026][6 · Oct 29, 2026] See CR2032 vs CR2025 vs CR2016.
- Rechargeables run at a lower voltage. Ni-MH AA and AAA start at about 1.2 V; Panasonic says most devices built for 1.5 V dry cells work on them, but not all.[7 · Oct 29, 2026]
Before you swap
Energizer's guide says to replace batteries with the size and type the device maker specifies, to replace all of them at once, and not to mix old and new batteries or different types or makes.[1 · Oct 29, 2026]
