Compatible CMOS battery for HP Pavilion dm4-3055dx

This DBTLAP lithium CMOS battery replaces the RTC backup cell on the motherboard of an HP Pavilion dm4-3055dx laptop. It keeps the real-time clock and BIOS settings alive when the main power is removed. The part is new and tested before shipping.

Fits the motherboard coin-cell socket

The battery slots directly into the existing CMOS holder on the system board, requiring no soldering or adapter cables. It frees the builder from tracking down an OEM-specific coin cell and restores persistent firmware configuration immediately after installation.

Maintains clock and BIOS data under continuous

The lithium chemistry delivers a steady low-current supply for the real-time clock and CMOS memory during long periods without AC or main battery power. It sustains date, time and boot-order settings reliably until the main power source returns.
