Replacement battery for ThinkPad T570 T580 P51S P52S

This new lithium-ion battery delivers 32 Wh at 15.28 V with a rated capacity of 2095 mAh. It is built as a direct internal replacement for Lenovo ThinkPad T570, T580, P51S and P52S series notebooks. The unit matches original part numbers 00UR890, 01AV493, SB10L84121, 00UR891, SB10L84122, 00UR892 and SB10L84123. Buyers who need a different voltage or capacity should verify their original battery label before ordering.

Installation tools included in the package

The box supplies the tools required to open the laptop base and swap the battery without sourcing a separate kit. This reduces the risk of damaging casing clips or stripping screws during the swap. No software, drivers or calibration utilities are bundled; the operating system handles power management automatically. Users who expect a diagnostic disc or firmware updater will not find one here.

Capacity of 32 Wh at 15.28 V

The 32 Wh rating determines how long the notebook can run on a full charge under a given workload. If the original battery carried a higher watt-hour figure, runtime will be shorter; if it was lower, runtime will improve. Matching the 15.28 V nominal voltage is essential — a different voltage will prevent the laptop from recognising the pack or could cause charging errors. Confirm the original battery model number on the back cover before purchase.

Questions about this item

Will the 00UR891 battery need replacement tools when it eventually wears out?

The replacement includes installation tools, so no separate toolkit is required when you swap the 32Wh pack later.

What capacity limit appears first during long sessions on the 15.28V 2095mAh cell?

The 32Wh rating sets the runtime ceiling; sustained loads drain the 2095mAh capacity before any other limit is reached.

How much heat or fan noise does the 00UR891 add when the ThinkPad runs all day?

The Li-ion pack itself generates minimal extra heat and no noise; system thermals stay governed by the laptop’s own cooling design.
