VOLTCRAFT ML2032 Rechargeable Lithium Button Cell 65 mAh 3 V 100-Pack (VC-18689110)

Unlike disposable CR2032 cells that end up in landfills after a single use, the VOLTCRAFT ML2032 is a rechargeable lithium manganese dioxide button cell engineered for long-term service in memory backup, real-time clocks, and small portable devices. With a nominal voltage of 3 V and a capacity of 65 mAh, it delivers stable power over hundreds of charge cycles, making it a cost-effective and eco-friendly alternative to primary cells. This bulk pack of 100 cells is ideal for maintenance departments, electronics workshops, and OEM applications where reliable backup power is essential.

Highlights

• Rechargeable lithium manganese dioxide (ML) chemistry with up to 500 charge/discharge cycles
• Nominal voltage 3 V, capacity 65 mAh, energy content 0.195 Wh
• Standard 2032 size: 20 mm diameter, 3.2 mm height, flat top terminals
• Low self-discharge rate: less than 1% per year at 20°C
• Wide operating temperature range: -20°C to +60°C
• RoHS compliant and equivalent in size to non-rechargeable CR2032
• Bulk pack of 100 cells for volume requirements

In daily use

The ML2032 excels in applications that require infrequent but reliable power, such as CMOS memory backup, real-time clocks, remote controls, and small sensors. Its low self-discharge ensures that the cell retains charge during long periods of inactivity, while the flat top design allows easy integration into standard button cell holders. For charging, a current of 0.01C to 0.05C (0.65 mA to 3.25 mA) is recommended to maximize cycle life. The cells are supplied in bulk packaging, making them convenient for automated assembly or high-volume replacement programs.
