DBTLAP CMOS Battery for HP TouchSmart tm2

This lithium CMOS battery replaces the RTC backup cell on HP TouchSmart tm2 laptop motherboards. It keeps the system clock and BIOS settings alive when the main power is removed. The part is supplied new and tested before shipping. It is not a main laptop battery and will not power the system.

Simple two-wire connector installation

The battery uses a standard two-wire plug that fits the motherboard header on the TouchSmart tm2. No soldering or special tools are required for the swap. The main difficulty is reaching the header, which often involves removing the keyboard deck or base cover. Take care not to strain the fragile wires when routing the replacement.

Check motherboard header and voltage match

Verify that the existing CMOS cell uses the same two-pin connector pitch and 3 V lithium chemistry before ordering. Confirm the laptop model is exactly the TouchSmart tm2 series, as other HP lines use different headers. The package contains only the battery; no mounting adhesive or screws are included.
