Replacement battery for ThinkPad T570 T580 P51S P52S

This 15.2V lithium-ion pack restores mobile power to compatible ThinkPad models. It is aimed at owners whose original battery no longer holds a charge or prevents the laptop from starting. The 32Wh capacity matches the factory specification for daily office and travel use. Buyers needing longer runtime than 32Wh provides should consider higher-capacity alternatives.

Internal 4-cell design with smart protection circuit

The battery fits inside the chassis using the original mounting points and connector layout. A built-in smart chip manages charge cycles and protects against overcharge over-discharge and short circuits. UL CE FCC and RoHS certifications confirm compliance with safety standards. The 4-cell polymer construction keeps weight low while maintaining structural rigidity. Users who require an external hot-swap battery cannot use this internal-only module.

32Wh 2100mAh at 15.2V decides compatibility

This single rating determines whether the pack matches the laptop's power budget and firmware expectations. The voltage and capacity figures must align with the machine's original SB10L84121 SB10L84122 SB10L84123 or 00UR890 00UR891 00UR892 01AV493 part numbers. A mismatch in watt-hours or cell count will cause reporting errors or charging failure. Verify the exact model label before purchase.
