Compatible ThinkPad series

This Dr. Battery 01AV490 unit replaces the internal power source in ThinkPad T470 T480 T570 T580 P51s P52s A475 A485 and TP25 models. It is built for owners of those laptops who need a fresh 47Wh lithium polymer pack rated at 11.4V and 4400 mAh.

Replaces worn original packs

The battery substitutes Lenovo part numbers 01AV425 01AV452 01AV423 and SB10K97597 when the factory cell no longer holds a useful charge. The upgrade is worth it when runtime has dropped below what the 4400 mAh rating can still deliver in daily office or mobile use.

Lithium polymer chemistry limits

Li-polymer cells degrade with heat and deep discharge cycles so runtime will gradually fall from the rated 47Wh. The pack includes over-charge over-discharge over-heat and short-circuit protection but cannot prevent normal capacity loss over time.

Questions about this item

Does the 8.0 x 1.5 x 0.8 cm battery fit the internal bay of a ThinkPad T480?

The pack measures 8.0 x 1.5 x 0.8 cm and matches the original 01AV490 form factor, so it seats in the same internal bay without modification.

Which screw or latch step is most often missed when swapping the 11.4 V pack in a ThinkPad P52s?

After sliding the pack in, the single bottom-case screw must be re-tightened; skipping it leaves the battery loose and the system will not recognise the 4400 mAh cell.

When should the 47 Wh Li-polymer unit be replaced in a ThinkPad A485?

Replace the battery once run-time falls well below the original 47 Wh capacity or the pack shows swelling, whichever occurs first.
