Powering CMOS motherboards, remote controls, and medical devices, the Maxell CR2032 3V Lithium Coin Cell Battery maintains a 3V charge via Lithium Manganese Dioxide chemistry. Across a 10-year shelf life, the cell retains energy. Capacity increases to 220mAh from the previous 160mAh version. Under the 3.2mm casing, the unit stores more power than the thinner 2.5mm predecessor.
Key Features
- Leak-Resistant Construction: Specialized seals prevent internal electrolyte discharge. Stops corrosion from damaging sensitive electronic PCB components.
- Stable 3V Discharge: Flat discharge curve maintains constant voltage. Prevents data loss in RTC battery backup systems and memory modules.
- 10-Year Shelf Life: Low 1% annual self-discharge rate. Stays ready after years of storage in humid Bangladesh environments.
- Temperature Resilience: Functional range from -20°C to +85°C. Withstands extreme heat inside computer cases or outdoor sensors.
Frequently Asked Questions
Is Maxell CR2032 rechargeable?
No, this is a primary lithium battery. Charging it causes internal pressure buildup and potential cell rupture.
How long does Maxell CR2032 last?
In storage, it retains charge for a decade. In a desktop motherboard, it typically powers the BIOS for 3 to 5 years.
Can I use CR2032 instead of CR2025?
At 3.2mm, this cell is 0.7mm thicker than a CR2025. It only works if the battery slot has physical space for the extra height.
