## Summary description

Dell M717H is a 3V coin-cell replacement battery designed for use in portable devices' RTC/CMOS memory. It provides backup power to maintain system settings and real-time clock when the main power is removed. Compact and easy to install, it suits laptops, motherboards and other small electronics requiring a 3V coin battery.

## Long description

Dell M717H 3V Coin Cell (RTC CMOS) is a compact replacement battery intended for maintaining real-time clock and CMOS settings in portable devices. Designed to fit applications that require a standard 3V coin battery, this cell supplies standby power when the main power source is removed, preserving BIOS/UEFI settings, system time and configuration parameters. Its small diameter and low profile make it suitable for installation on laptop motherboards, small single-board computers and other portable electronics that accept a 3V coin cell.
Advantages
The battery offers stable 3V output suitable for RTC and CMOS backup, ensuring continuity of system settings and clock accuracy during power loss. Its compact format simplifies replacement in confined spaces and minimizes interference with nearby components. The design emphasizes reliable shelf life and low self-discharge characteristics typical of lithium coin cells, providing long-term standby service without frequent replacement. The cell’s standard shape and voltage make it compatible with many devices that specify a 3V coin battery for RTC/CMOS backup.
Suitable for
 Laptops and notebooks that use a 3V coin cell for RTC/CMOS memory
 Desktop motherboards with accessible coin-cell holders
 Embedded systems and single-board computers requiring a backup clock battery
 Small electronic devices and industry equipment with 3V coin-cell requirements
Key specifications
 Nominal voltage: 3 V
 Physical format: coin / button cell suitable for standard 3V holders
 Primary chemistry: lithium-based coin cell for low self-discharge
 Typical use: RTC and CMOS backup power
 Operating temperature range: suitable for typical consumer electronics environments
How to use
Before replacing the battery, power down the device and disconnect the main power source and any batteries. Locate the coin-cell holder on the motherboard or device board and note the polarity marking to ensure correct orientation. Carefully remove the old coin cell using a non-conductive tool if necessary, then insert the new 3V coin cell with the correct polarity. Reconnect power and verify system time and BIOS/UEFI settings; update as needed. Observe electrostatic discharge precautions and follow the device manufacturer’s instructions for battery replacement.
Usage recommendations
Store unused batteries at room temperature away from direct sunlight and metallic objects. Replace the coin cell when the system reports CMOS/RTC warnings, when timekeeping becomes inaccurate, or at regular service intervals. Dispose of spent batteries according to local regulations for battery recycling and hazardous waste.
