DBTLAP CMOS Battery For Acer Aspire 7741G

SKU CH-XY6Z-7Q5MT

Lithium CMOS battery replaces the BIOS RTC cell on Acer Aspire 7741G motherboards

  • Battery typeLithium
  • Reliable BIOS timekeeping with lithium CMOS cell
  • Direct replacement for Acer Aspire 7741G motherboard
  • Tested before shipping for dependable performance
  • High-quality construction resists leakage and failure
  • Single battery included for quick installation

Direct replacement for Acer Aspire 7741G

This CMOS battery is designed as a direct replacement for the Acer Aspire 7741G laptop. It restores the system clock and BIOS settings when the original cell is exhausted. The part is new and tested before shipping. It is intended for motherboard RTC power, not the main laptop battery.

Lithium coin-cell interface limits

The lithium coin cell provides the low continuous current required by the real-time clock circuit. It cannot supply power for any other subsystem. When the cell voltage drops below the threshold the firmware loses stored configuration and the clock resets at every cold start.

Capacity suited to RTC retention

The cell holds enough charge to maintain CMOS memory for the typical service interval of the platform. It comfortably handles years of standby time while the main battery is removed. It runs out when the internal chemistry is depleted, requiring a fresh replacement to regain reliable boot configuration.
