DBTLAP CMOS Battery for HP Envy dv6-7210us

This replacement CMOS battery is designed for the HP Envy dv6-7210us laptop motherboard. It restores BIOS clock and configuration retention when the original cell fails. The lithium chemistry provides stable voltage for real-time clock operation. It is intended for repair technicians and owners servicing this specific model.

Lithium coin cell capacity and headroom

The lithium coin cell supplies the low current needed for CMOS memory and RTC functions. It comfortably maintains settings during long periods of mains disconnection. Capacity is sufficient for typical service life in this platform. The cell will eventually deplete and require another replacement.

Thermals noise and power draw in normal use

As a passive coin cell it generates no heat and produces no audible noise during operation. Power draw is limited to the microampere-level leakage of the motherboard RTC circuit. No active cooling or ventilation considerations apply. The component sits idle on the board until system power is removed.

Questions about this item

Will this CMOS battery fit the HP Envy dv6-7210us motherboard I am keeping?

It is built as a direct replacement for the HP Envy dv6-7210us, so it matches the original motherboard socket and voltage.

How can I confirm the battery is working after I install it?

The system clock will hold the correct time and date through cold boots, and BIOS settings will no longer reset to defaults.

What comes in the package and is anything else needed?

The box contains one lithium CMOS battery; no extra cables or tools are included or required for the swap.
