Small round batteries power many everyday devices. CR2025 and CR2032 batteries serve similar purposes but work differently. Selecting the correct type ensures devices function properly and last longer.
This guide examines five distinctions between CR2025 and CR2032 batteries. Dimensions, energy storage, voltage, cost, and typical applications receive detailed attention. Common questions about these batteries find clear answers here.
CR2025 Battery vs CR2032: Short answer
The CR2032 is thicker (3.2mm vs 2.5mm) and lasts longer, while the CR2025 fits tighter spaces.
1. Size and Thickness: Why It Matters
Physical dimensions separate these two battery types.
- CR2025: Measures 20mm across and 2.5mm thick
- CR2032: Shares the 20mm diameter but extends to 3.2mm thickness
The extra 0.7mm in the CR2032 allows greater energy storage. Some compact devices lack space for the thicker variant.
Device manuals specify required battery dimensions. Ignoring these guidelines risks damaging battery compartments.
2. Battery Capacity: Which Lasts Longer?
Milliampere-hours (mAh) indicate energy storage capacity.
- CR2025: Stores approximately 160mAh
- CR2032: Holds around 220mAh
The CR2032 delivers power for extended periods, benefiting energy-intensive devices like wireless doorbells and medical monitors.
Digital clocks and remote controls often perform well with the slimmer CR2025.
3. Voltage: Are They Interchangeable?
Both variants supply 3 volts of electrical potential.
Some devices accept either battery if physical space permits. Others strictly require one specific type.
Research from Energizer demonstrates that incorrect battery installation can generate excess heat.
4. Price Comparison: Is One Cheaper?
Market prices show minor variations.
- CR2025: Typically retails near \$1.50 per unit
- CR2032: Generally costs about \$2.00 each
The CR2032 often proves more economical over time due to its extended service life.
5. Common Uses: Which Battery Fits Your Device?
| Device Category | Recommended Power Source |
|---|
| Vehicle key remotes | CR2032 |
| Kitchen scales | CR2025 |
| Heart rate monitors | Manufacturer specification |
| Electronic toys | CR2025 |
Manufacturer guidelines provide definitive answers for battery selection.
