DBTLAP CMOS RTC Battery for Toshiba Libretto 30

SKU CH-VR20-SA605

A lithium CMOS RTC battery that keeps the system clock and BIOS settings on a Toshiba Libretto 30

  • Battery TypeLithium
  • Direct CMOS replacement for Libretto 30 motherboards
  • Lithium chemistry keeps system clock and BIOS settings alive
  • Pre-tested unit ships ready for immediate installation
  • Single battery included matches original form factor exactly
  • Restores date/time retention on faulty or dead CMOS cells

Compatible CMOS battery for Libretto 30

This DBTLAP lithium cell replaces the CMOS RTC battery on a Toshiba Libretto 30 motherboard. It is a dedicated board-level component, not a main laptop power pack. The unit arrives new and tested, ready to restore system clock and BIOS settings. One battery is included in the package.

Lithium coin cell interface limits

The lithium chemistry provides stable low-current output for real-time clock and CMOS memory retention. It is designed for the specific holder and voltage requirements of the Libretto 30 mainboard. Polarity and physical dimensions must match the original socket exactly. No charging circuit or external connector is involved.

Capacity and headroom for BIOS retention

The cell delivers sufficient capacity for long-term CMOS configuration storage and accurate timekeeping during mains-off periods. It comfortably handles the minimal continuous drain of the RTC subsystem. Service life ends when the voltage drops below the threshold needed to preserve BIOS parameters, requiring another direct replacement.

Questions about this item

Which DBTLAP CMOS RTC battery version suits my Toshiba Libretto 30?

This DBTLAP battery is built for the Toshiba Libretto 30 and ships as a single lithium CMOS RTC unit ready to install.

What does the lithium chemistry mean once the battery is fitted to the motherboard?

The lithium cell keeps the real-time clock and BIOS settings alive when the main power is off, so the Libretto 30 retains date, time and hardware configuration.

What interface does this CMOS battery use and what does it limit in practice?

It connects via the standard two-pin motherboard header used on the Libretto 30, limiting use to that specific CMOS RTC socket.
