Is CR2032H interchangeable with similar codes?

What do the letters in CR2032H mean?

Under the IEC naming system, C is the assigned code for lithium–manganese dioxide — not taken from the spelling of those chemicals — and R means round (coin or button). The numbers encode size. Same diameter with a different first letter is a different battery. Full guide: CR vs LR vs SR.

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.

Notes

High-drain CR2032-class primary (Li-MnO2). Prefer when the device names H; not LIR/ML.
