Lenovo L23C4P70 Replacement Battery Review

Lenovo L23C4P70 replacement battery, a 15.6V 90Wh pack for the ThinkPad P1 Gen 7 mobile workstation.

90Wh is near the top of what most airlines allow without special approval, worth checking if you travel with this workstation.

What to check before you buy

Confirm Gen 7 on the base of your ThinkPad P1, since earlier P1 generations use different battery codes despite the shared model name.
