Replacement battery for ThinkPad T470 T480 A285

This Dr. Battery Professional Series unit is a brand-new lithium-polymer replacement designed for Lenovo ThinkPad T470 T480 A285 A485 and ThinkPad 25 laptops. It restores reliable mobile power for business users who need dependable runtime during office work or travel. The pack is built with OEM-grade cells and includes integrated protection against over-charge over-discharge overheating and short-circuit conditions. It is not for buyers who need a higher-capacity pack or a different form factor.

11.46 V 2000 mAh lithium-polymer cell chemistry

The single specification that decides fit is the electrical rating of 11.46 volts and 2000 milliampere-hours in a lithium-polymer construction. This matches the original Lenovo part numbers 01AV419 01AV420 01AV421 01AV489 SB10K97576 SB10K97577 SB10K97578 and 3ICP6/38/64. Systems requiring a different voltage or capacity will not operate correctly with this unit.

No bundled accessories or software included

The package contains only the battery itself with no additional cables tools drivers or management utilities. Installation relies on the laptop’s existing battery compartment and firmware so no extra software changes the experience. Buyers who expect a screwdriver kit or calibration utility must source those separately.

Questions about this item

What does the 11.46 V rating mean when the battery is installed in a ThinkPad T470?

The 11.46 V rating matches the original Lenovo part numbers 01AV419, 01AV420 and 01AV421 so the system recognises it as a standard 3-cell pack and reports capacity normally.

What connector standard does this pack use and what does it limit?

It uses the proprietary Lenovo internal connector keyed for ThinkPad T470, T480, A285, A485 and 25 models; the keying prevents insertion in other chassis.

Will the 8.0 x 1.5 x 0.8 cm case fit the internal battery bay of a ThinkPad A485 without modification?

Yes, the dimensions correspond to the factory SB10K97576, SB10K97577 and SB10K97578 form factor so it seats in the existing bay with the original screws.
