DBTLAP CMOS Battery for ASUS N55S

This lithium CMOS battery replaces the BIOS RTC cell on ASUS N55S laptop motherboards. It is a dedicated motherboard component, not a main laptop power pack. The part arrives new and tested, ready to restore system time and BIOS settings when the original cell fails.

Direct motherboard installation

The battery slots onto the motherboard without extra cables or adapters, freeing the builder from sourcing proprietary connectors. It suits repair technicians and owners who are comfortable opening the chassis and handling small board-level parts. No additional chargers, brackets or firmware tools are required for the swap.

Steady low-current retention

Lithium chemistry delivers a stable voltage for continuous real-time clock and CMOS memory power during long periods when the laptop is unplugged or off. The cell is verified before dispatch to confirm it holds charge under this constant, light load rather than only in brief test bursts.

Questions about this item

What is the first limit encountered during sustained use of the CMOS battery?

The lithium CMOS battery maintains the system clock and BIOS settings until its charge is depleted over years of continuous operation.

Does the battery produce any noise, heat or power draw while the laptop runs all day?

The CMOS battery is a passive component; it generates no noise, no measurable heat and draws negligible power during normal laptop use.

What must the buyer already own for this CMOS battery to work?

A compatible ASUS N55S laptop motherboard with the correct CMOS battery connector is required for installation.
