Description

Maxell lithium battery

• Nominal Voltage: 3.0 V.

• Typical Capacity: ~ 220 mAh for the CR2032 size.

• Size: Diameter ~20.0 mm, Height ~3.2 mm.

• Chemistry: Lithium / Manganese-Dioxide (Li/MnO₂) coin cell type.

• Operating Temperature Range: Typically –20 °C to +85 °C (depending on model).

• Self-discharge: Very low (approx ~1% per year for some models) which is excellent for long-term use.

This Maxell CR2032 battery is excellent for small electronics such as:

• Real-time clocks (RTC) in motherboards or embedded systems

• Memory backup in microcontrollers and small devices

• Wearables, key-fobs, sensors and IoT devices that rely on a stable 3 V supply

• Small remotes, calculators, digital scales and other low-drain gadgets

Its stable voltage and low leakage make it highly dependable for devices that may sit idle for long periods between use.
