Steps
Fully shut down the laptop and unplug the charger and any cables. Check your warranty first, since opening an in-warranty unit may affect it.
Flip the laptop over and remove the bottom cover screws with the Phillips screwdriver. Keep them on a magnetic mat in the order they came out.
Slide the plastic pry tool into the seam and work around the edges to release the clips. Lift the bottom cover off gently.
Find the battery connector on the motherboard and unplug it before touching anything else. This cuts power and protects the board.
Remove the screws holding the battery in place, then lift the old battery out. Note its orientation so the new one goes in the same way.
Seat the new battery flat in the bay and refit its screws. Tighten them snug, not hard, to avoid cracking the housing.
Plug the battery connector back in firmly and check it sits straight. A loose connector is the usual cause of a laptop that won't start.
Press the bottom cover back on until the clips click, then refit the cover screws. Power on and test before you finish.
Charge the new battery to 100 percent, then run it down to about 5 percent once so the firmware reads capacity correctly.
Tips and common mistakes
Use plastic tools only, since metal can scratch the case or short the board.
Work on a clean, flat surface and keep screws grouped by location so none go missing.
Only fit a battery listed for your exact X1 Carbon model, as voltage and shape vary between generations.
If the laptop won't power on, recheck the battery connector and that all screws are back in.
Questions
Will replacing the battery void my warranty?
On an out-of-warranty laptop, a DIY swap affects nothing. If the unit is still covered, check Lenovo's policy before you open it.
How do I know the battery needs replacing?
Check battery wear with a tool like AIDA64. Once wear passes about 50 to 60 percent of original capacity, a new battery is worth it.
Can I use any compatible battery?
No. Use one specified for your ThinkPad X1 Carbon generation so the voltage, connector and fit are correct.
