This 52.5 Wh lithium-ion pack replaces Lenovo part numbers 41CP6, 41CP66 and 41CP56. It fits both Intel and AMD variants of the P16s Gen 1 as well as multiple T16 Gen 1 and Gen 2 models listed in the compatibility data. The black cell carries a 12 month warranty.
Voltage and capacity delivered
The unit supplies 15.44 V or 15.48 V at the rated 52.5 Wh, matching the original electrical specification. No extra cables, adapters or software utilities are included in the package.
Capacity headroom for mobile workloads
A 52.5 Wh pack typically powers a P16s through a standard business day of document editing, video calls and light compilation. Heavy GPU compute, sustained 4K video export or external monitor arrays will drain the charge faster and require mid-day recharging.

Questions about this item
When will the 52.5 Wh lithium-ion pack need replacing?
The 12 month warranty covers defects, and lithium-ion cells gradually lose capacity over repeated charge cycles.
What limits runtime when the ThinkPad P16s Gen 1 runs heavy workloads all day?
The 52.5 Wh capacity at 15.44 V / 15.48 V sets the total energy available before a recharge is required.
How much heat or noise does the battery produce during continuous use?
The battery itself has no moving parts and generates only modest warmth during charge or discharge.
