Cameron & Co DS-CS-HQC600BU CMOS laptop battery 0.2 Ah green

SKU CH-FEFR-9EVB9

A lithium CMOS battery rated at 0.2 Ah for HP Pavilion, Elitebook and compatible Acer or Lenovo laptops

  • Product typeBattery
  • Keeps system clock accurate with 0.2 Ah lithium cell
  • Compatible with HP CQ60, CQ50 and CQ70 series laptops
  • Also fits Acer and Lenovo models using 41R7611
  • Green housing identifies the battery at a glance

Compatible CMOS Battery for HP and Acer

The Cameron & Co DS-CS-HQC600BU is a lithium CMOS battery rated at 0.2 Ah with a green housing. It replaces part numbers 23.22047.001 and 417076-001 for HP systems and 41R7611 for Acer and Lenovo notebooks. The cell maintains real-time clock and BIOS settings when main power is removed. Builders needing a higher-capacity CMOS cell or a different connector pitch should look elsewhere.

Sustained Retention Performance

The lithium chemistry delivers stable voltage over the multi-year service interval typical for CMOS applications. Self-discharge remains low enough to preserve configuration data during extended storage or when the main battery is depleted. No recharge cycle is required because the cell is primary rather than rechargeable. Systems that expect a rechargeable CMOS module will not charge this unit.

Thermal Noise and Power Profile

As a non-rechargeable button cell the component generates no audible noise and negligible heat during normal operation. Current draw is limited to microampere-level leakage from the real-time clock circuit. The green housing identifies the Cameron Sino DS-CS-HQC600BU model for quick visual verification during installation. No active cooling or special airflow considerations apply.

Questions about this item

Does the 0.2 Ah lithium CMOS battery generate any noticeable heat or noise during continuous operation?

The CMOS battery is a passive lithium cell with no moving parts or active circuitry, so it produces no audible noise and negligible heat while maintaining system time and BIOS settings.

What connector or cable must already be present on the motherboard for this green DS-CS-HQC600BU battery to plug in?

The battery uses a standard two-pin CMOS header with a keyed plug that matches the original HP part numbers 23.22047.001 and 417076-001 found on compatible EliteBook and Pavilion boards.

Will this replacement CMOS battery work alongside the original main battery in an HP Pavilion dv2000 series laptop?

Yes, the CMOS cell operates independently from the main laptop battery, so it will keep the real-time clock and CMOS memory alive regardless of the primary battery's condition or charge state.
