Lithium battery 3V0 BAT-3V0-CR2032

BAT-3V0-CR2032

New product

CR2032 lithium coin cell 3V (BAT-3V0-CR2032). Compact, long shelf life (up to 10 years) — suitable for motherboards (RTC), remotes, sensors and encrypted keys.

More details

More info

The BAT-3V0-CR2032 is a standard CR2032 lithium coin cell with a nominal voltage of 3 V and typical dimensions of approximately 20 mm × 3.2 mm. Typical capacity for these cells is in the ~220–240 mAh range, making them suitable for low-drain portable and embedded electronics.

Applications and benefits

CR2032 cells are widely used for RTC/CMOS backup on motherboards, remote controls, wireless detectors, secure key fobs and other low-power devices. Their low self-discharge and long shelf life (up to 10 years) make them convenient for maintenance-sensitive applications.

Operating conditions

These lithium cells operate over a wide temperature range (commonly quoted around -40 °C to +60 °C), though capacity and output voltage may decrease at extreme temperatures. Compared with alkaline cells, CR2032 typically performs better at low temperatures, which is beneficial for outdoor sensors and cold environments.

Recommendations and safety

Do not recharge: CR2032 cells are primary (non-rechargeable). Use batteries from reputable sources and observe correct polarity when replacing. Avoid short circuits. Dispose of used cells according to local battery recycling regulations.

Practical advice

For indoor devices in stable, warm environments alkaline cells may be acceptable, but for outdoor sensors, cold storage areas (garages, sheds, containers) or where long-term stable voltage is required, CR2032 lithium cells generally provide more reliable performance.
