Dr. Battery 2000 mAh 11.46V Li-polymer replacement

This Dr. Battery Professional Series unit replaces the internal power source for Lenovo ThinkPad T470, T480, A285, A485 and ThinkPad 25 models. It uses OEM-grade lithium-polymer cells rated at 2000 mAh and 11.46V to restore mobile operation. Integrated circuitry guards against over-charge, over-discharge, overheating and short-circuit conditions. The battery fits the original chassis without modification.

Replaces Lenovo part numbers 01AV419 01AV420

The swap is worthwhile when the original pack no longer holds a useful charge or shows swelling. It also suits owners of compatible ThinkPad series who need a spare for extended travel. Units with soldered or non-removable cells cannot use this replacement. Buyers whose laptops require a different voltage or connector should verify the part number before ordering.

Limited to 11.46V 2000 mAh lithium-polymer form

Runtime scales with workload and screen brightness, so heavy multitasking reduces available hours. The pack cannot exceed its rated capacity, and calibration cycles may be needed for accurate fuel-gauge reporting. Extreme temperatures accelerate permanent capacity loss. Systems that demand a higher-wattage or higher-voltage pack will not operate correctly with this unit.

Questions about this item

Does the 8.0 × 1.5 × 0.8 cm form factor fit the internal battery bay of a ThinkPad T480 without modification?

Yes, the dimensions match the original Lenovo battery compartment for T470, T480, A285, A485 and ThinkPad 25 models.

What is the correct sequence for installing the battery and which step do users often skip?

Power off the laptop, disconnect the AC adapter, remove the base cover, unplug the old battery connector, fit the new pack, reconnect the cable, replace the cover, then charge fully before first use; many forget the initial full charge.

How can I tell when the 2000 mAh Li-polymer pack needs replacing?

Replace the battery when runtime drops well below your normal workload, the system reports a capacity warning, or the pack shows physical swelling.
