CMOS Battery for HP Pavilion dm1-3260br

This lithium CMOS battery is designed for the HP Pavilion dm1-3260br motherboard. It supplies the real-time clock and BIOS memory when the main power is off. Buyers needing a replacement for a depleted or faulty RTC cell will find this part a direct fit. It is not a main laptop battery and will not power the system during use.

Thermals and Power Draw

The cell operates at very low current, so it generates no measurable heat and makes no noise. Power draw is negligible and will not affect the laptop’s main battery life or charger load. No active cooling or special ventilation is required for this component.

Included Battery and Testing

The package contains one CMOS battery that has been tested before shipping. This single unit replaces the original RTC cell on the motherboard. No additional cables, brackets or software are supplied, and none are needed for installation.

Highlights

  • Compatible with HP Pavilion dm1-3260br motherboard
  • Lithium chemistry provides stable RTC power
  • Ready-to-install replacement for faulty CMOS unit
  • Pre-tested before dispatch for reliable operation
  • Supplies BIOS clock and settings retention

Questions about this item

How do I install the CMOS battery on the HP Pavilion dm1-3260br motherboard and which step is often missed?

Open the chassis, locate the coin-cell holder on the motherboard, remove the old cell, insert the new lithium battery with the positive side facing up, then reassemble; the step often missed is clearing the BIOS settings afterwards so the system clock and hardware configuration reset correctly.

What maintenance or replacement will this CMOS battery need later?

The lithium CMOS battery typically lasts several years; when the system clock starts losing time or BIOS settings revert at each boot, replace it with an identical coin cell — no other maintenance is required.

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

The practical limit is the cell’s finite charge capacity; after multiple years of continuous powering the real-time clock and CMOS memory, the voltage drops below the threshold needed to retain BIOS settings, requiring replacement.
