DBTLAP

DBTLAP standard battery for COMPAQ Presario CQ61-320SG

SKU CH-J35C-XA1GJ

Lithium CMOS battery replaces the BIOS clock cell on Presario CQ61-320SG motherboards

  • Battery TypeLithium
  • Keeps system clock and BIOS settings accurate
  • Lithium chemistry provides stable low-voltage power
  • Designed specifically for Compaq Presario CQ61-320SG
  • Tested before shipping to ensure reliability
  • Replaces faulty or cracked CMOS battery

Direct replacement for CQ61-320SG

This lithium CMOS battery restores BIOS settings and real-time clock function on the Compaq Presario CQ61-320SG motherboard. It is a direct-fit component for that specific model. The pack contains one tested cell ready for installation. Builders repairing other laptop series should look elsewhere.

Steady voltage under constant drain

The cell maintains a stable output during the continuous low-current draw of CMOS memory and the real-time clock. It avoids the voltage sag that causes lost BIOS configuration or system time drift. Each unit is tested before shipping to confirm reliable performance over the full service interval.

Upgrade from a depleted original

This part replaces a dead or leaking factory CMOS battery that no longer holds charge. The jump is worth it when the machine loses date, time or BIOS settings after power-off. It does not replace the main laptop battery and will not extend runtime.

Highlights

  • Keeps system clock and BIOS settings accurate
  • Lithium chemistry provides stable low-voltage power
  • Designed specifically for Compaq Presario CQ61-320SG
  • Tested before shipping to ensure reliability
  • Replaces faulty or cracked CMOS battery

Questions about this item

How much power does the CMOS battery draw while the laptop runs all day?

The lithium CMOS battery only supplies a tiny standby current to keep the real-time clock and BIOS settings alive; it does not power the system during normal operation.

What must already be in the COMPAQ Presario CQ61-320SG for this battery to work?

The laptop needs a compatible motherboard socket for a standard CMOS coin cell; no extra cables or adapters are required.

Will this replacement CMOS battery work with the original BIOS chip on the CQ61-320SG?

Yes, it is a direct replacement for the factory-fitted CMOS battery and maintains the same voltage for the existing BIOS and real-time clock circuitry.
