The Maxell CR2032 3V Lithium Coin Battery powers small electronics including motherboards, car fobs, and digital scales. Lithium Manganese Dioxide chemistry provides a 220mAh capacity for long-term discharge stability. With a 10-year shelf life, this Japan-made cell retains its charge while sitting in storage for future use.
Key Features
- Leak-Proof Sealing: Structural sealing prevents electrolyte leakage across the 20mm diameter frame. Stops chemical corrosion from destroying sensitive internal components in expensive wristwatches.
- Voltage Stability: Consistent 3V output throughout the entire discharge cycle. Maintains accurate timekeeping in CMOS circuits until the battery reaches full depletion.
- Temperature Resilience: Operating range spanning -20°C to 85°C. Withstands high heat inside parked vehicles or humid Dhaka electronics enclosures without losing power.
- High Energy Density: 220mAh capacity packed into a 3.2mm height profile. Supplies reliable energy to high-drain pulse devices like Apple AirTags or remote controls.
Frequently Asked Questions
Is Maxell CR2032 rechargeable?
This lithium manganese dioxide cell is a primary battery and cannot accept a recharge. Forcing current into the cell leads to overheating or internal leakage.
How long does Maxell CR2032 last?
A 220mAh capacity typically runs a standard wristwatch for two to four years. In low-drain CMOS applications, the cell sustains motherboard data for up to five years.
