Rome Tech CR2032 CMOS Replacement Battery

This Rome Tech CR2032 lithium coin cell replaces the RTC BIOS battery in compatible Dell Latitude and XPS laptops. It supplies 3 V to maintain system time and CMOS settings when the main power is off. The part includes a two-pin wire connector and heat-shrink insulation for a direct plug-in fit.

Installation takes about ten minutes

The battery arrives with a matching connector and an identification label for quick verification. Most issues arise when the old connector is brittle or the cable routing is tight, so handle the wires gently and ensure the plug seats fully. The protective packaging helps prevent damage during handling.

Limited to devices using a CR2032 cell

The battery will not work in systems that need a different voltage, cell size or connector layout. It holds charge for up to ten years in storage, but runtime in a laptop depends on the motherboard's power draw. Buyers whose machines use a soldered or proprietary battery module cannot use this part.
