DBTLAP CMOS RTC Battery for Dell Inspiron 9400

SKU CH-6KE6-0RVDP

Lithium CMOS RTC battery replaces the motherboard clock cell in Dell Inspiron 9400 laptops

  • Battery typeLithium
  • Reliable system timekeeping with lithium CMOS battery
  • Direct replacement for Dell Inspiron 9400 motherboard
  • Ready to install with pre-tested quality assurance
  • Fixes BIOS reset errors from faulty RTC cell
  • Single-unit package includes one CMOS battery

Direct Dell Inspiron 9400 Compatibility

This CMOS RTC battery is built specifically for the Dell Inspiron 9400 laptop motherboard. It supplies the low-voltage power needed to keep BIOS settings and the real-time clock running when the main system is off. The lithium cell arrives new and pre-tested so it can be installed immediately. It is not a main laptop battery and will not power the system itself.

For Maintainers Restoring BIOS Function

The part suits technicians and owners fixing a dead clock, lost CMOS configuration or boot-time checksum errors on the named model. It will not help users whose machine needs a primary power pack, a different form-factor cell or a soldered-in replacement. Buyers without soldering equipment should verify the connector style before ordering.

Lithium Coin Cell Chemistry Decides Fit

The lithium chemistry sets the voltage and physical profile that the Inspiron 9400 motherboard expects. A mismatched chemistry would prevent the real-time clock from keeping accurate time or retaining BIOS data. Confirm that the original cell is a removable lithium coin type before fitting this replacement.

Questions about this item

Which CMOS RTC battery version fits the Dell Inspiron 9400?

This lithium CMOS RTC battery is listed as compatible for the Dell Inspiron 9400 and replaces the motherboard BIOS clock battery.

What does the lithium chemistry mean once the battery is installed?

The lithium cell provides stable 3 V power to keep the system clock and BIOS settings alive while the laptop is off or unplugged.

What interface does this CMOS battery use and what does that limit?

It connects via the standard two-pin motherboard header, so it only powers the real-time clock and CMOS memory, not the main laptop battery.
