Product information

Description

The Cameron Sino CMOS/BIOS battery MR652 is a replacement internal backup cell designed to preserve BIOS settings and the real-time clock on compatible Dell laptops. It provides low-power standby supply to the system board when the main battery is removed or the laptop is disconnected from AC power. This spare part is intended for use as a direct-fit replacement in models that accept the MR652 form factor and connector type, ensuring continued retention of BIOS configuration, date and time settings.

Advantages

This CMOS/BIOS battery offers a compact design that fits into the internal battery compartment of supported Dell notebooks. It provides stable low-voltage backup to maintain BIOS memory and RTC accuracy, reducing the risk of lost settings after power removal. As a dedicated replacement part, it allows quick restoration of system board backup power without replacing the main battery or motherboard.

Suitable for

  • Maintaining BIOS settings and system clock on Dell Precision M4600 and M6600
  • Preserving configuration on Dell Latitude X1 and E-series models (E6320, E6420, E6430, E6520, E7240)
  • Repair and refurbishment of laptops where CMOS battery failure causes loss of BIOS settings
  • Service operations requiring a direct internal BIOS backup replacement cell

Key specifications

  • Type: Internal CMOS/BIOS backup battery designed for motherboard installation
  • Form factor: Small coin-cell style pack with connector and cable suitable for compatible Dell systems
  • Function: Provides standby power to real-time clock and non-volatile BIOS memory
  • Voltage: Low-voltage backup output appropriate for typical CMOS circuitry
  • Compatibility: Designed to match physical and electrical requirements of specified Dell laptop models

How to use

Power down the laptop, disconnect any external power and remove the main battery if applicable. Open the access panel or keyboard area following the laptop manufacturer’s service instructions to reach the motherboard. Carefully disconnect the existing CMOS/BIOS battery connector from the board and replace it with the Cameron Sino MR652, routing the cable to match the original placement. Reassemble the laptop and reconnect main power; verify BIOS settings and system time in the firmware setup utility and adjust if necessary.

Usage recommendations

Handle internal components with electrostatic discharge (ESD) precautions. If uncertain about disassembly, consult a qualified technician or official service manual for your Dell model to avoid damage. After installation, confirm correct BIOS operation and replace the main battery or perform additional repairs only after verifying retention of settings.
