DBTLAP CMOS Battery for ASUS N10J-A2

SKU CH-E4KN-3P4KA

Replacement CMOS battery for ASUS N10J-A2 motherboards, tested before shipping

  • Battery TypeLithium
  • Lithium chemistry provides stable BIOS clock power
  • Direct replacement for ASUS N10J-A2 motherboards
  • Pre-tested unit ensures reliable first boot
  • Single battery package simplifies installation
  • New condition guarantees full rated capacity

Compatible CMOS Battery for ASUS N10J-A2

This lithium CMOS battery is designed for the ASUS N10J-A2 motherboard. It supplies power to the real-time clock and BIOS settings when the main battery is removed or depleted. The unit is tested before shipping to confirm reliable operation. It is not a main laptop battery and cannot power the system itself.

Thermals Noise and Power Draw

As a passive coin-cell component the battery generates no heat and makes no noise during normal use. It draws only the tiny current required to keep the CMOS memory alive. No active cooling or power-management considerations apply to this part.

Replaces a Failed Original CMOS Cell

This battery replaces a dead or leaking factory CMOS cell that causes lost BIOS settings, incorrect system time or boot errors. The upgrade is worth it when the original no longer holds a charge. Buyers who need a main power battery or a higher-capacity CMOS variant will not be served by this part.

Highlights

  • Lithium chemistry provides stable BIOS clock power
  • Direct replacement for ASUS N10J-A2 motherboards
  • Pre-tested unit ensures reliable first boot
  • Single battery package simplifies installation
  • New condition guarantees full rated capacity

Questions about this item

How do I install this CMOS battery in my ASUS N10J-A2 and what step is often missed?

Disconnect the main battery and power adapter first, then swap the coin cell on the motherboard; the step often missed is clearing the CMOS jumper afterwards so the BIOS recognises the new cell.

What maintenance or replacement will this DBTLAP lithium CMOS battery need later?

The lithium cell typically lasts several years; when the system clock drifts or BIOS settings reset at power-off, replace the coin cell with an identical type.

What limit appears first under sustained use of this CMOS battery?

The practical limit is the lithium chemistry itself — after multiple years the voltage drops below the threshold needed to retain RTC data, causing time and configuration loss.
