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.

Device-specific caveats

From manufacturer-backed notes on devices that use CR2016 — not generic advice.

Connected wearable with conventional CR2016 — do not confuse with Tough Solar CTL/ML rechargeable Edifice models.
Eco-Drive and other rechargeable cells (MT*, CTL*, SLB*, …) are excluded from this disposable CR/SR publish set.
