Lenovo ThinkPad CMOS Replacement

This 3.0V 150mAh lithium cell replaces the 93P4905 CMOS battery in Lenovo ThinkPad X100e and X120e models including 2876, 3506, 3507 and 3508 variants. It restores system clock and BIOS settings retention when the original coin cell is depleted. The green non-rechargeable unit is 100% OEM compatible and brand new.

Thermals Noise and Power Draw

As a 0.45Wh lithium CMOS cell it draws negligible current and produces no audible noise or measurable heat during normal operation. The battery maintains CMOS memory with a steady 3.0V output over its service life. No active cooling or thermal management is required for this component.

Bundled Accessories and Software Impact

The package contains a single battery unit with no cables, adapters, mounting hardware or software utilities included. Installation requires only physical replacement of the existing coin cell on the system board. No drivers or configuration tools are needed for the hardware to function.

Questions about this item

How do I install the DS-CS-LVX100BU CMOS battery in my ThinkPad X100e, and what step is often missed?

Remove the old cell, match the 3.0V polarity, and seat the 24.00 x 20.20 x 3.72 mm unit firmly; the step often missed is resetting the BIOS clock after replacement.

What maintenance or replacement will this 3.0V 150mAh lithium cell need later?

As a non-rechargeable lithium CMOS battery, it requires no maintenance; plan to replace it when the system loses date and time settings, typically after several years.

What limit appears first under sustained use of this 0.45W h battery?

The 150mAh capacity determines runtime; the first limit is voltage drop below the level needed to retain CMOS data, ending the useful life.
