Buyers Needing Other Form Factors
This part suits owners of the listed Medion and ThinkPad models who need a direct CMOS replacement. It does not suit users whose devices require a different voltage, connector layout or physical size. Builders working on desktop motherboards or other laptop series should verify the exact part number before ordering. The 20.00 x 20.00 x 3.80mm dimensions limit compatibility to the named systems.
200mAh 3.0V Specification
The decisive specification is the 200mAh capacity at 3.0V in a 20.00 x 20.00 x 3.80mm package. This exact combination determines whether the battery fits the CMOS holder and maintains the real-time clock correctly. ISO9001, RoHS and CE certifications confirm manufacturing quality. Overcharge, over-discharge and short-circuit protection are built in for safe operation.
