Direct replacement for Lenovo G50

This lithium CMOS battery is a direct replacement for the Lenovo G50 laptop motherboard. It restores the real-time clock and BIOS settings when the original cell has failed. The part is supplied new and tested before shipping.

Coin-cell form factor for motherboard mounting

The standard coin-cell design fits the existing motherboard holder without modification. It is intended for the CMOS BIOS RTC circuit only and does not power the main laptop battery. Installation requires opening the chassis to access the board.

Upgrades a depleted or leaking original cell

This unit replaces a factory-fitted CMOS battery that no longer holds charge or shows signs of leakage. The jump is worth it when the system loses time, date or BIOS configuration between boots. It is not for users needing a main power battery.

Highlights

  • Keeps system clock accurate with lithium CMOS cell
  • Direct fit for Lenovo G50 motherboard

Questions about this item

What battery type does the DBTLAP CMOS replacement for the Lenovo G50 use?

The replacement uses a lithium coin cell that supplies the 3 V needed to keep the BIOS clock and settings alive when the laptop is off.

What physical space does this battery need inside the Lenovo G50?

It fits the standard motherboard coin-cell holder already present on the G50 mainboard, so no extra bracket or adapter is required.

How is the battery installed and what step do people often miss?

Open the case, unplug the old cell from its two-pin connector, snap the new one in with the correct polarity, then enter the BIOS to reset the date and time.
