Product Description The CR2032 with a 2-Pin Connector is a specialized power solution designed for devices where the battery cannot be mounted directly on the PCB. Enclosed in a protective heat-shrink sleeve, this battery features pre-attached flexible leads and a polarized mini-connector. It is the standard replacement battery for laptop BIOS/CMOS settings, industrial PC motherboards, and compact medical devices. The wired design allows the battery to be tucked away in tight corners or taped to the side of a chassis, making it ideal for space-constrained electronics.

Key Features

  • Plug-and-Play: Features a polarized 2-pin connector for instant, solder-less installation.

  • Insulated Protection: Wrapped in heat-shrink tubing to prevent accidental shorts against the metal chassis or other components.

  • Flexible Mounting: The wire leads allow the battery to be positioned away from heat-generating components like CPUs.

  • High Reliability: Maintains a stable 3V output for years, ensuring Real-Time Clock (RTC) accuracy and memory retention.

  • Vibration Proof: The wired connection is far more secure than a standard coin cell holder in high-vibration environments.

Technical Details

  • Dimensions (Battery): 20.0 mm (Diameter) x 3.2 mm (Height)

  • Standard Discharge Current: 0.2mA

  • Weight: Approx. 4.0g (including wires/connector)

  • Self-Discharge Rate: < 1% per year

  • Operating Temperature: -20°C to +60°C

Prototyping and Engineering Tips from Robogears

  • Polarity Verification: Before plugging this into your motherboard or controller, always verify the wire colors. Red is typically Positive (+) and Black is Negative (-). While JST connectors are keyed, some laptop manufacturers use a reversed pinout.

  • Mounting Tip: Since this battery is encased in heat-shrink, you can easily secure it to the inside of your project box using double-sided foam tape or a small dab of hot glue.

  • RTC Backup: This battery is perfect for powering the DS3231 or DS1307 RTC modules if you want to move the battery off the module board to save vertical height in your enclosure.

  • Maintenance: When replacing a CMOS battery in a laptop, ensure the device is completely powered off and the main battery is removed before disconnecting the old coin cell to prevent any static damage to the BIOS chip.

Package Includes

  • 1 x CR2032 3V Lithium Coin Cell with 2-Pin Connector
