Compatible CMOS Battery

This DBTLAP lithium CMOS battery is designed for the HP TouchSmart tm2-2100 laptop motherboard. It replaces the original RTC battery that maintains BIOS settings and system time when the main power is off. The unit is supplied new and tested before shipping. It is not a main laptop battery and will not power the system during use.

Lithium Coin-Cell Chemistry

The single specification that determines fit is the lithium coin-cell chemistry required by the HP TouchSmart tm2-2100 motherboard. This battery delivers the correct voltage and form factor for the CMOS socket. Installing a different chemistry or voltage will prevent the board from retaining BIOS configuration. Verify the original part visually before fitting.

Low Power Retention

In normal operation the cell draws only microampere current to keep the real-time clock and CMOS memory alive. It produces no audible noise and generates no perceptible heat inside the chassis. The lithium chemistry provides a long service life under this minimal continuous load. No active cooling or special power management is required.

Questions about this item

What does the CMOS battery do once it is installed in my HP TouchSmart tm2-2100?

It keeps the system clock running and stores BIOS settings such as boot order and hardware configuration when the laptop is completely powered off.

What connector standard does this CMOS battery use and what does that limit?

It uses a standard two-pin wire lead that plugs directly into the motherboard header, limiting installation to boards with the matching pin spacing and polarity.

What physical space or mounting does this battery need inside the laptop?

The coin-cell body sits in a small clip or socket on the motherboard and the short wire harness routes to the nearby header, requiring only a few millimetres of clearance.
