Replacement battery for ThinkPad P15 and P17 Gen 1

This new lithium-ion battery replaces part numbers L19C6P71, L19L6P71, 31CP5/55/90 and several 5B10W and SB10T codes. It fits ThinkPad P15 Gen 1, P15 Gen 2, P17 Gen 1 and T15g Gen 1 models. The black pack delivers 94 Wh at 11.52 V or 11.55 V. Buyers with other laptop series cannot use this pack.

Sustained output from a 94 Wh lithium-ion cell

A 94 Wh rating means the pack can supply its rated power for longer periods than lower-capacity units, reducing the frequency of recharge cycles during mobile work. Lithium-ion chemistry maintains a stable voltage curve across the discharge cycle. The two listed voltages are interchangeable per the supplier note. Users needing multi-day runtime without mains access will still require an external power source.

Practical limits of the proprietary ThinkPad

The battery connects through the manufacturer’s dedicated connector, so it only works in the listed ThinkPad models. No universal charging standard or third-party dock interface is supported. Capacity will gradually decline with age and charge cycles, a normal characteristic of lithium-ion cells. Systems outside the compatibility list cannot accept this pack.

Questions about this item

How much power does the 94Wh battery draw during a full day of use?

The battery stores 94Wh at 11.52V or 11.55V; actual draw depends on the ThinkPad workload, not the battery itself.

Must my ThinkPad P15 or P17 Gen 1 already have a working 11.52V or 11.55V battery connector for this replacement to fit?

Yes, it replaces part numbers L19C6P71, L19L6P71, 31CP5/55/90, 5B10W13958, 5B10W13959, SB10T83201 and SB10T83202, so the original connector is required.

Will the 11.52V and 11.55V variants both work in my ThinkPad P15 Gen 1 20SUS0GA00 alongside the original charger?

The supplier states L19C6P71 and L19L6P71 are compatible with each other despite the voltage difference and either will be shipped.
