DBTLAP CMOS Battery for HP Pavilion dv7-6118eg

SKU CH-28F1-2S36Q

Replacement lithium CMOS battery restores BIOS settings on HP Pavilion dv7-6118eg laptops

  • Battery TypeLithium
  • Replaces the CMOS BIOS RTC battery on compatible HP Pavilion motherboards
  • Lithium chemistry provides stable voltage for real-time clock and BIOS settings
  • Tested before shipping to confirm reliable operation
  • Direct replacement for faulty, cracked or broken CMOS units
  • Single battery included for straightforward installation

Purpose and Compatibility

This DBTLAP CMOS battery is a lithium coin cell designed to maintain BIOS settings and the real-time clock on HP Pavilion dv7-6118eg laptop motherboards. It serves as a direct replacement when the original cell fails and the system loses time or configuration data.

Interface Constraints

The battery connects through the standard two-pin header found on the target motherboard, so no soldering or adapter is required. Polarity must match the board layout; incorrect orientation will prevent the RTC circuit from functioning.

Deciding Specification

The critical detail is the exact model match to the HP Pavilion dv7-6118eg; this cell is not intended for other laptop series or for the main system battery compartment. Buyers needing a primary power pack or a different form factor should look elsewhere.
