Questions about this item
Does the 11.61 V 58 Wh 3-cell pack run hot or draw extra power during all-day use?
The replacement cell operates at the same 11.61 V and 58 Wh rating as the original, so thermal output and power draw match the factory design.
What must I already own to install the L23M3P74 battery?
A compatible ThinkPad T14s Gen 6 (21N1 or 21N2) and a small Phillips screwdriver for the bottom case screws.
Will this 11.61 V pack work alongside the original charger and BIOS on my T14s Gen 6 21N1?
Yes, it replaces OEM part numbers L23M3P74, L23D3P75, SB11H56304, SB11H56305, 5B11H56403 and 5B11H56404, so the existing charger and firmware recognise it normally.
