CMOS replacement for HP Inspiron and Pavilion

This Cameron & Co DS-CS-HCQ620BU is a lithium CMOS battery rated at 0.2 Ah. It is built for HP Inspiron 9100 and a wide range of Pavilion dv4 and dv7 series notebooks. The green cell restores system clock and BIOS settings when the original coin cell is exhausted. It is a direct-fit part for legacy HP laptops.

No bundled accessories or software included

The package contains only the CMOS battery itself. There are no cables, adapters, drivers or installation tools supplied. The change it makes is purely functional: replacing a depleted on-board cell so the laptop retains date, time and firmware configuration between power cycles. No additional components are required beyond basic disassembly tools.

0.2 Ah lithium cell for specific HP models

The single specification that decides fitment is the 0.2 Ah lithium chemistry matched to the listed HP part numbers. It covers Inspiron 9100, Pavilion dv4 models including 1100, 1200, 3000, 3100 and 3124, plus Pavilion dv7 models from the 1400, 4000, 4100 and 6000 series. Buyers whose laptop model is not in this explicit compatibility list cannot use this battery.

Questions about this item

How often will the DS-CS-HCQ620BU CMOS battery need replacing in an HP Pavilion dv7-4000?

The lithium CMOS battery typically lasts several years before the system clock drifts or BIOS settings reset, signalling replacement.

What is the capacity limit of the 0.2 Ah cell during continuous operation?

The 0.2 Ah rating supports low-drain CMOS circuitry for years; it is not designed for high-current or sustained-load use.

Does the green DS-CS-HCQ620BU generate noticeable heat or noise inside a Pavilion dv4-1100?

No, the coin-cell CMOS battery runs passively with negligible heat output and no moving parts, so it stays silent and cool.
