Rome Tech CR2025 CMOS Battery

This replacement CMOS battery uses a CR2025 lithium coin cell rated at 3V to maintain BIOS settings and real-time clock data. It is built for Lenovo ThinkPad models including X120E, X121e, X130e, X131e, X140e, Edge 11, Edge 13, Edge E130 and T430u. The unit ships new with a two-wire FI connector for direct installation.

Suits owners of listed ThinkPads losing BIOS

This part suits owners of the listed ThinkPad models who need to restore BIOS configuration retention and clock accuracy. It will not suit users whose motherboard requires a different coin-cell size, voltage or connector type. Buyers needing a soldered-in battery or a different form factor should look elsewhere.

Pre-wired connector removes soldering

The bundled two-wire FI connector allows a direct plug-in replacement without soldering or modification. An identification label lets you verify authenticity before fitting. The cell holds charge for up to 10 years in storage, so a spare can be kept on hand for future maintenance.
