  • Lithium chemistry provides stable RTC backup power
  • Pre-tested unit ensures reliable motherboard timekeeping
  • Single battery included for direct installation
  • Designed for CMOS BIOS memory retention

DBTLAP CMOS Battery for Tecra M11-17V

This replacement CMOS battery is designed for the Toshiba Tecra M11-17V laptop. It supplies power to the motherboard real-time clock and BIOS memory when the main battery is removed or depleted. The lithium cell arrives tested and ready for installation. It addresses startup errors caused by a dead or failing original battery.

Installation and compatibility

The unit fits directly onto the motherboard CMOS header inside the Tecra M11-17V chassis. No additional cables or adapters are required beyond the standard connector. Replacing the cell restores accurate system time and preserves BIOS settings across power cycles. It frees the user from re-entering configuration data at every boot.

Capacity limits and service life

The lithium chemistry provides stable voltage for long-term CMOS retention. The battery handles normal standby current draw for the RTC and NVRAM circuitry. It cannot power the main laptop components or serve as a primary power source. Service life ends when the cell voltage drops below the threshold needed to maintain BIOS data.

Highlights

  • Compatible replacement for Tecra M11-17V systems
  • Lithium chemistry provides stable RTC backup power
  • Pre-tested unit ensures reliable motherboard timekeeping
  • Single battery included for direct installation

Questions about this item

How long does the lithium CMOS battery typically last in a Toshiba Tecra M11-17V before it needs replacing?

The lithium cell usually holds BIOS settings for several years; when the clock starts losing time or CMOS checksum errors appear on boot, the battery has reached its practical limit.

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

No, a passive lithium coin cell produces no audible noise and negligible heat while maintaining the real-time clock and CMOS memory.

What connector or cable does the Tecra M11-17V require so this replacement battery fits the motherboard?

The board uses the standard two-pin CMOS header; the replacement ships with the matching plug and 11 17 cm lead length for direct installation.
