CR1632 3V Lithium Button Cell Battery (5-Pack) | Beidongli

Beidongli CR1632 – Compact 3V Button Cell for Small Home Automation Devices

The Beidongli CR1632 is a compact 3V lithium coin cell battery with a capacity of 140 mAh , perfect for smaller electronic devices that require less power. This non-rechargeable coin cell offers reliable performance in a compact size for everyday use.

Technical specifications

• Voltage : 3.0 Volt
• Capacity : 140 mAh
• Dimensions : Diameter 16 mm, thickness 3.2 mm
• Type : Lithium-manganese dioxide (Li/MnO₂) button cell
• Weight : Approximately 1.8 grams
• Shelf life : Storage possible for 7-8 years due to low self-discharge
• Reference Numbers : Also known as BR1632, ECR1632, L50

Smart home and home automation applications

The CR1632 is mainly used in compact devices:

• Small wireless sensors such as compact door and window sensors
• Car keys with keyless entry and remote controls
• Smart watches and fitness trackers
• Medical devices such as glucose meters
• Calculators, thermometers and scales

Performance & Considerations

The CR1632, with its smaller 16mm diameter , is specifically designed for compact battery compartments where the larger CR2032 (20mm diameter) doesn't fit. Its lower capacity (140 mAh vs. 210-230 mAh for the CR2032) makes it particularly suitable for devices with low power consumption .

Lifespan : Under normal load (15kΩ at 20°C), the CR1632 lasts approximately 684 hours, or about 29 days of use. For devices used only once or twice a day (such as car keys or occasional sensors), this translates to months to years of use.

Beidongli positions these batteries as an affordable alternative to premium brands. For critical smart home applications with high power consumption, we recommend the larger CR2032, but for compact, low-power devices, the CR1632 is an excellent choice.
