Dr. Battery 2100 mAh 11.4 V for ThinkPad

This new lithium-polymer replacement battery restores reliable mobile power to compatible Lenovo ThinkPad laptops. It is built with OEM-grade cells and includes built-in protection against over-charging, over-discharging, overheating, and short-circuit conditions. The unit fits ThinkPad T470, T480, T570, T580, P51s, P52s, A475, A485, and TP25 series models. It replaces original Lenovo part numbers such as 01AV423, 01AV452, and the SB10K series.

Fits listed ThinkPad T, P, A, TP25 models

Buyers owning a ThinkPad T470, T480, T570, T580, P51s, P52s, A475, A485, or TP25 can use this 2100 mAh pack as a direct replacement. It suits professionals needing dependable runtime for office and mobile workstation tasks. Users with other ThinkPad families or different voltage requirements should verify their original part number before ordering. The battery is not universal across all Lenovo lines.

2100 mAh capacity at 11.4 V decides fit

The single specification that determines compatibility is the 2100 mAh capacity combined with the 11.4 V nominal voltage. Only laptops designed for this exact electrical rating will operate correctly and safely. Matching the original Lenovo part number, such as 01AV423 or SB10K97597, confirms the correct fit. Physical dimensions of 8.0x1.5x0.8 and weight of 0.4 kg align with the original internal bay.

Questions about this item

How long do the Li-polymer cells in this 2100 mAh 11.4 V battery last before needing replacement?

The Professional Series uses OEM-grade Li-polymer cells rated for many charge cycles; typical lifespan depends on usage patterns and charge habits rather than a fixed cycle count.

What limits runtime first during sustained workloads on this 24 Wh pack?

The 2100 mAh capacity at 11.4 V defines the total energy available, so capacity is the primary limit under continuous load.

Does the battery generate noticeable heat or noise during all-day operation?

It has no moving parts and built-in over-heating protection, so it runs silently with minimal heat under normal office workloads.
