Compatible ThinkPad models

This replacement battery fits Lenovo ThinkPad A485, P51s, P52s, T470, T480, T570 and T580 systems. It is built for professionals who need dependable mobile power across several business-class notebook families. The 11.4V lithium-polymer pack restores original runtime for daily office and field work.

Built-in safety protections

The Professional Series design adds over-charge, over-discharge, over-heat and short-circuit safeguards. These circuits protect both the battery and the notebook during extended charging cycles and demanding workloads. OEM-grade cells and factory testing ensure consistent output without extra software or cables.

24 Wh capacity limit

At 2100 mAh the pack stores roughly 24 Wh, which may fall short for users who need all-day unplugged sessions. Heavy multitasking, high screen brightness or peripheral loads will drain the charge faster than larger-capacity alternatives. Buyers who want more storage should consider higher-capacity options.

Questions about this item

Does the 11.4V 2100mAh Li-polymer pack need any scheduled cell balancing or calibration cycles?

No scheduled balancing is required; the built-in protection circuit manages cell health automatically during normal charge and discharge.

What is the first limit reached during continuous all-day discharge of this 24Wh battery?

The 2100mAh capacity is the limiting factor; once the stored charge is depleted the pack must be recharged before further use.

How much heat or noise does the battery produce when the ThinkPad runs on it for a full workday?

The battery is silent and generates only modest warmth typical of Li-polymer cells under normal load; no fan or active cooling is involved.
