DBTLAP CMOS Battery for ASUS S550C Lithium

SKU CH-FZ2P-M0YR8

Replacement CMOS battery for ASUS S550C motherboards, lithium type, tested before shipping

  • Battery TypeLithium
  • Restores BIOS settings with lithium CMOS cell
  • Direct replacement for ASUS S550C motherboard
  • Ready to install with pre-attached connector
  • Each unit tested before shipping for reliability
  • New battery manufactured in 2022

Direct Replacement CMOS Battery

This lithium CMOS battery is manufactured as a direct replacement for the ASUS S550C laptop motherboard. It restores the real-time clock and BIOS settings when the original cell is depleted. The part is supplied new and tested before shipping. It is intended for component-level repair, not as a main laptop power source.

Lithium Coin-Cell Chemistry

The single specification that determines compatibility is the lithium coin-cell chemistry required by the ASUS S550C motherboard. A different chemistry or voltage will not maintain BIOS data correctly. This unit matches the original electrical profile for reliable operation. No other form factor or voltage variant is supplied.

Low Power Passive Operation

The battery draws negligible current and generates no measurable heat during normal operation. It operates silently with no moving parts or active cooling requirements. Power consumption is limited to the microampere-level maintenance of the RTC circuit. The component has no impact on system thermals or acoustic profile.

Questions about this item

How does the lithium chemistry affect real-world CMOS retention on an ASUS S550C?

The lithium cell supplies steady 3 V power to the real-time clock and BIOS settings, keeping date, time and firmware configuration intact whenever the main battery is removed or depleted.

What connection standard does this CMOS battery use with the S550C motherboard?

It connects through the standard two-pin JST header found on the ASUS S550C board, so no soldering or adapter is required.

What physical space is needed to install this battery in the laptop chassis?

The coin-cell form factor fits the existing motherboard holder, and the attached lead reaches the header without strain inside the S550C chassis.
