Questions about this item

Will the L19C4P73 battery fit my ThinkPad X1 Titanium Yoga Gen 1 without any extra parts?

Yes, it is a direct replacement for part numbers L19C4P73, L19M4P73, 5B10W13965 and SB10T83208 and fits the X1 Titanium Yoga Gen 1 chassis.

Can I keep using my existing 65 W USB-C charger with this 7.72 V 44.5 Wh battery?

The battery charges through the laptop's standard USB-C power delivery port, so your current Lenovo 65 W adapter will charge it normally.

How can I confirm the new battery is recognised and reporting the correct 44.5 Wh capacity in Windows?

Open the Lenovo Vantage app or run 'powercfg /batteryreport' in Command Prompt; both will show the design capacity as 44.5 Wh when the battery is seated properly.
