With a 220mAh capacity, the Maxell CR2032 Lithium 3V Coin Battery powers CMOS circuits and small electronics. Under a 3V nominal load, it maintains steady discharge across -20 to 85°C. This Japan-made cell fits standard 20mm diameter slots in motherboards or car remotes.
Key Features
- Leakage Resistance: Solid Li/MnO2 construction prevents internal electrolyte leakage. It prevents corrosion on sensitive motherboard circuits.
- 10-Year Shelf Life: Low 1% annual self-discharge rate enables decade-long storage. The battery remains usable after long periods in storage despite road dust.
- Japan Quality Build: Precision manufacturing at 20.0mm diameter and 3.2mm height. It fits tight battery compartments without loose connections or rattling.
- 220mAh Capacity: High energy density output at a 0.2mA discharge current. This provides power to low-drain calculators for several years.
Frequently Asked Questions
Is Maxell CR2032 rechargeable?
This lithium coin cell is non-rechargeable. Charging attempts cause internal pressure and potential electrolyte leakage.
How long does Maxell CR2032 last?
Shelf life reaches 10 years with a 1% annual discharge rate. In a standard CMOS setup, it typically runs for 3 to 5 years.
