Compatible CMOS Battery for Dell Studio XPS 1645

This DBTLAP lithium CMOS battery replaces the BIOS RTC cell on Dell Studio XPS 1645 motherboards. It is a new component tested before shipping to ensure reliable real-time clock and BIOS settings retention. The package includes one battery intended for motherboard installation, not main laptop power.

Ideal for Dell Studio XPS 1645 owners

This part suits users whose Dell Studio XPS 1645 shows BIOS reset errors or clock drift caused by a depleted cell. It is not for anyone needing a main rechargeable laptop battery or a CMOS cell for a different laptop model or motherboard platform.

Lithium coin cell chemistry

The battery uses lithium chemistry to provide the stable low-current supply required for CMOS memory. Matching this chemistry and the Dell Studio XPS 1645 compatibility is the single specification that confirms it as the correct replacement part.
