CR2032H aliases and equivalent names
Common search labels and closely related markings include 2032H. Packaging conventions vary, so confirm the compatibility grade, voltage, chemistry, and dimensions shown below before replacing the battery.
Voltage
3 V
Chemistry
LiMnO2
Capacity
220–240 mAh
Size
20×3.2 mm
CR2032H20 × 3.2 mm
Exact equivalents
Exact- CR2032 — Standard / lower-pulse sibling — same size and 3V class

Frequently Asked Questions
Can I use a regular CR2032 instead of CR2032H?
Usually yes for size and voltage. If the device draws sharp pulses (some remotes and sensors), the H cell may last longer or stay more reliable near end of life.
Is CR2032H rechargeable?
No. It is still a primary lithium coin cell. Rechargeable 2032-size cells are labeled LIR2032 or ML2032.
Should I always trust cross-reference charts?
Use this guide as a starting point, then confirm with your device manual or manufacturer. Voltage, chemistry, and physical fit must all match for safe operation.

Selection notes
If the old cell says CR2032H, a Maxell H pack is the closest match. A fresh name-brand CR2032 usually works in the same holder. Do not confuse H with LIR (rechargeable) or BR (high-temperature chemistry).
