Direct replacement for ThinkPad A475 and A485

The KingSener 01AV420 is a new 24Wh lithium-ion battery built to match the original part numbers 01AV419, 01AV421 and 01AV489. It fits Lenovo ThinkPad A475, A485 and TP25 models without modification. The 11.4V pack uses high-quality cells and a tested PCB to deliver the full design capacity of 2.1Ah.

Fits the existing battery bay with no extra parts

Installation uses the same screws and connector as the factory unit, so no tools beyond a basic screwdriver are required. The black casing matches the original dimensions, freeing you from adapter cables or chassis changes. It restores mobile operation for users whose original pack no longer holds a useful charge.

No bundled software or accessories change

The package contains only the battery itself. No drivers, calibration utilities or mounting hardware are included. First use benefits from two or three full charge and discharge cycles at low current. Storing the pack above 80% charge once a month preserves health during long idle periods.
