Replacement battery for ThinkPad P-series

This 94Wh lithium-ion pack replaces part numbers L19C6P71, L19L6P71, 5B10W13958, 5B10W13959, SB10T83201, SB10T83202 and 31CP5/55/90. It fits ThinkPad P15 Gen 1, P15 Gen 2, P17 Gen 1 and T15g Gen 1 models. The black unit ships new with a 12-month warranty. Voltage is 11.55V and capacity is 94Wh.

Fits mobile workstations without extra hardware

The battery slots directly into the existing compartment on supported ThinkPad chassis. No adapter, cable or firmware update is required. It frees the user from carrying a bulky AC adapter during field work. Compatibility spans multiple part-number revisions so one SKU covers several service tags.

Sustained capacity under daily cycles

Lithium-ion chemistry delivers the rated 94Wh across repeated charge and discharge cycles typical of mobile workstation workloads. The 11.55V output remains stable during extended compile, render or simulation sessions. Capacity retention follows standard Li-ion aging curves rather than dropping sharply after a few months.

Questions about this item

How long does the 94Wh capacity last under sustained load before the 11.55V output drops?

The 94Wh lithium-ion pack is rated to deliver 11.55V throughout its discharge cycle; actual runtime under sustained load depends on the laptop's power draw.

Does the battery run hot or make noise during all-day use in a ThinkPad P15 or P17?

As a passive lithium-ion cell it has no moving parts and generates only normal operating heat; no fan noise is produced.

Which specific ThinkPad models must I already own for this 31CP5/55/90 part to fit?

It replaces L19C6P71, L19L6P71, 5B10W13958, 5B10W13959, SB10T83201, SB10T83202 and fits ThinkPad P15 Gen 1, P15 Gen 2, P17 Gen 1 and T15g Gen 1 units listed in the compatibility data.
