DBTLAP CMOS Battery for ASUS X50Z

SKU CH-J25D-GN3K4

Lithium CMOS battery replaces the BIOS RTC cell on ASUS X50Z motherboards, tested before shipping

  • Battery TypeLithium
  • Lithium chemistry provides stable CMOS power
  • Direct fit for ASUS X50Z motherboards
  • Pre-tested unit ensures reliable BIOS operation
  • Replaces faulty or cracked RTC batteries
  • Single battery packaged for immediate installation

Direct X50Z motherboard fit

This lithium CMOS battery is built specifically for the ASUS X50Z motherboard. It supplies the low-voltage backup that keeps BIOS settings and the real-time clock alive when the main power is removed. The part is new and tested before it ships. Buyers who need a main laptop power pack will not find it here.

Drop-in BIOS power replacement

The cell installs directly on the X50Z board without adapters or soldering. It restores persistent CMOS data so the system remembers boot order, time and hardware configuration across shutdowns. A faulty or depleted original cell is the only problem this component solves. Builders looking for a rechargeable primary battery should look elsewhere.

Single tested cell in the pack

The package contains one pre-checked CMOS battery and nothing else. No cables, brackets or software utilities are bundled. The pre-shipment test simply confirms the cell holds its rated voltage. Users who expect a multi-cell kit or a diagnostic tool will need to source those separately.

Highlights

  • Lithium chemistry provides stable CMOS power
  • Direct fit for ASUS X50Z motherboards
  • Pre-tested unit ensures reliable BIOS operation
  • Replaces faulty or cracked RTC batteries
  • Single battery packaged for immediate installation

Questions about this item

How long will the CMOS battery keep the BIOS clock and settings accurate under continuous daily use?

The lithium cell is designed to hold the real-time clock and BIOS configuration for years of normal laptop operation before voltage drops below the threshold.

Does the battery generate any noticeable heat or noise while the laptop runs all day?

No, the CMOS battery is a passive lithium cell with no moving parts, so it produces no audible noise and no measurable heat during continuous use.

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

The ASUS X50Z motherboard must provide the standard two-pin CMOS header and a compatible BIOS that recognises a 3 V lithium coin cell.
