DBTLAP CMOS Battery for MSI Wind U100 standard battery

SKU CH-NKF4-5TACA

Lithium CMOS battery replaces the BIOS RTC cell on MSI Wind U100 motherboards, tested before shipping

  • Battery TypeLithium
  • Replaces the CMOS battery in MSI Wind U100 laptops
  • Lithium cell keeps system clock and BIOS settings accurate
  • Tested before shipping to confirm reliable operation
  • Single replacement unit included for straightforward installation
  • High-quality construction restores motherboard power backup

Direct MSI Wind U100 Fit

This CMOS battery is built to replace the original RTC cell in the MSI Wind U100 laptop motherboard. It restores BIOS settings and system clock accuracy when the factory battery fails. The lithium chemistry matches the board’s voltage and form factor. Buyers needing a main laptop battery or a different motherboard model should look elsewhere.

Low Self-Discharge Lithium Cell

The lithium construction holds charge for years with negligible leakage current. Normal operation draws micro-amperes, so the cell runs cool and silent inside the chassis. No active cooling or power management is required. Systems with non-standard voltage rails or proprietary connectors are not supported.

Single Battery Shipped Tested

Each unit is tested before shipping and arrives as a single loose cell ready for soldering or socket insertion. No cables, holders, adapters or software are included in the package. Installers must provide their own tools and observe correct polarity. Buyers expecting a pre-wired harness or installation kit will need to source those separately.

Questions about this item

How do I install the CMOS battery in my MSI Wind U100 and which step is often missed?

Open the chassis, locate the coin-cell socket on the motherboard, remove the old cell, insert the new lithium unit with the positive side facing up, then reassemble; the step most people miss is entering the BIOS afterwards to reset the date, time and boot order.

What maintenance or replacement will this CMOS battery need later?

The lithium CMOS battery requires no routine maintenance; it will eventually lose its charge after several years and should then be replaced with another compatible coin cell to keep BIOS settings retained.

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

The practical limit is the finite lithium chemistry lifespan — typically several years of continuous operation — after which the cell voltage drops too low to maintain the real-time clock and CMOS memory.
