Replacement CMOS Battery for ThinkPad X-Series

This non-rechargeable lithium cell supplies 3.0V and 0.2Ah to maintain system time and BIOS settings when the main power is removed. It is built for Lenovo ThinkPad X200, X201, X40, X41, X60 and X61 models including tablet and slim variants. The green housing matches the original OEM appearance for direct board placement.

Practical Limits of a Primary Coin Cell

The 0.60Wh capacity cannot be recharged by the laptop and will deplete over several years of continuous timekeeping duty. Once voltage drops below the CMOS threshold the system loses date, time and boot-order data on every cold start. No software update or power-management setting can extend the chemical life of this primary lithium chemistry.

Build Quality and Connector Implications

The unit measures 25.72 x 20.10 x 3.50 mm and carries part numbers 23.2004.181 and 92P1004 for exact board-level compatibility. Its two-pin lead layout plugs straight into the motherboard header without adapters or soldering. The compact footprint fits the tight chassis clearances of the listed X-series ultraportables and tablet convertibles.
