DBTLAP CMOS Battery for Tecra A11-128

This DBTLAP lithium CMOS battery is a direct replacement for the real-time clock cell on a Toshiba Tecra A11-128 motherboard. It arrives new and tested, ready to restore BIOS settings and system time when the original coin cell fails. The package includes one battery.

Suitable for Tecra A11-128 owners.

This part suits technicians and owners servicing a Tecra A11-128 who need to replace a depleted or cracked CMOS battery. It is not for users looking for a main laptop battery to power the system, nor for any other laptop model or motherboard.

Lithium chemistry for CMOS retention

The battery uses lithium chemistry to supply the low continuous current required for CMOS memory and real-time clock retention. This single specification determines whether the cell matches the motherboard's requirements.

Questions about this item

Which version of this CMOS battery fits my Tecra A11-128?

The listing shows a single lithium CMOS RTC battery intended as a direct replacement for the Tecra A11-128 motherboard; no alternative versions or capacities are offered.

What does the lithium chemistry mean once the battery is installed on the motherboard?

Lithium chemistry provides a stable 3 V supply that keeps the real-time clock and BIOS settings alive when the laptop is unplugged, typically lasting several years before needing another swap.

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

It connects via the standard two-pin CMOS header on the Tecra A11-128 board, so the only practical limit is the header pin spacing — no proprietary interface or additional wiring is required.
