Dr. Battery 24Wh ThinkPad Replacement

This 24 watt-hour lithium polymer battery replaces the original Lenovo pack in ThinkPad T470, T480, T570, T580, P51s, P52s, A475, A485 and TP25 models. It supplies 11.4 volts and 2100 milliampere-hours for daily office and mobile workstation use. The cell measures 8.0 by 1.5 by 0.8 centimetres and weighs 0.4 kilograms. Built-in circuitry protects against over-charge, over-discharge, overheat and short-circuit conditions.

Upgrade From Degraded Internal Pack

It substitutes Lenovo part numbers 01AV422 through 01AV428, 01AV452, 01AV490, 01AV491, 01AV492, 4X50M08812 and the SB10K97579 to SB10K97597 series. The jump is worth it when the factory battery no longer holds a full charge, shuts down under load or shows swelling. Professional series OEM-grade cells restore the original runtime and voltage stability. Buyers who need a higher capacity pack or a hot-swappable second battery will not be served by this single internal unit.

Limited By Internal Form Factor

The brick fits only the internal battery bay of the listed ThinkPad families; it cannot power models that use a different connector, voltage or physical outline. Runtime scales with the 24Wh rating, so heavy workloads will drain it faster than larger optional packs. The 11.4V output is fixed and cannot be adapted for USB-C charging or external power banks. Users requiring extended off-grid operation must carry a compatible AC adapter or a separate high-capacity power bank.
