Not a substitute

Same diameter family; different thickness — not interchangeable

Rechargeables are not equivalents

Rechargeable coin cells (LIR, ML, VL, CTL and similar) are not drop-in replacements for disposable CR cells — voltage and charging requirements differ. Same size does not mean the same battery.

Size family

Edge thickness in the 16 mm family — thicker bar means thicker cell. Not to scale. Highlighted cell is this page.
