DBTLAP CMOS RTC Battery For Lenovo G50

This DBTLAP lithium CMOS RTC battery is built for the Lenovo G50 laptop motherboard. It maintains system time and BIOS settings when the main power is removed. The unit is new and tested before shipping. It is not a main laptop battery and will not power the system for portable use.

Sustained load behaviour

The battery delivers a steady low current to the real-time clock circuit over years of continuous operation. It is designed to hold charge through long periods when the laptop is unplugged or stored. Performance does not degrade in short bursts because the draw remains constant and minimal. Replacement restores reliable timekeeping after the original cell is exhausted.

Upgrade context

This part replaces a faulty, cracked or depleted CMOS coin cell that causes lost BIOS settings or system clock errors. The jump is worth it when the laptop shows incorrect time on every boot or fails to retain hardware configuration. It does not address main battery life, charging issues or power delivery to other components. Buyers who need a primary power source should look elsewhere.

Highlights

Questions about this item

How much power does the CMOS battery draw while the Lenovo G50 runs all day?

The lithium CMOS battery only supplies a tiny standby current to keep the real-time clock alive; it does not draw measurable power during normal daily use.

What must I already have in the laptop for this CMOS battery to work?

You need a Lenovo G50 motherboard with the correct two-pin CMOS header and a functional charging circuit for the lithium cell.

Will this replacement CMOS battery keep the clock accurate on an older Lenovo G50 that has been in storage?

Yes, the new lithium cell restores reliable RTC operation so the BIOS retains time and settings after long periods without main power.
