DBTLAP CMOS Battery for HP Pavilion dv3

SKU CH-6NAD-CFY4Q

Lithium CMOS battery replaces the BIOS RTC cell on HP Pavilion dv3 motherboards

  • Battery TypeLithium
  • Compatible with HP Pavilion dv3 laptops
  • Lithium chemistry provides stable CMOS power
  • Replaces faulty or cracked RTC batteries
  • Each unit tested before shipment
  • Single battery included in package

Product Identity

This DBTLAP CMOS battery is a lithium coin cell designed to maintain BIOS settings and the real-time clock on HP Pavilion dv3 laptop motherboards. It is a direct replacement for the original factory-fitted cell.

Upgrade Context

The battery replaces a depleted or leaking CMOS cell that causes lost BIOS configuration, incorrect system time or boot errors. The swap is worthwhile when the laptop shows those symptoms and the motherboard itself is otherwise functional.

Practical Limits

As a standard lithium coin cell it supplies a fixed low-voltage output and cannot be recharged by the laptop. Service life depends on the motherboard's standby current draw, so longevity will vary between individual dv3 units.

Highlights

  • Compatible with HP Pavilion dv3 laptops
  • Lithium chemistry provides stable CMOS power
  • Replaces faulty or cracked RTC batteries
  • Each unit tested before shipment

Questions about this item

What connector does the CMOS battery use to fit the HP Pavilion dv3 motherboard?

The battery ships with a pre-attached lead and plug that matches the HP Pavilion dv3 motherboard header.

How do I install the CMOS battery, and what step is often missed?

Unplug the old battery, route the new lead the same way, then press the connector firmly until it clicks; the step often missed is fully seating the plug.

When will this lithium CMOS battery need replacement?

Expect three to five years of service; replace when the system clock drifts or BIOS settings reset after power loss.
