Direct replacement for ThinkPad X280 and A285

This new lithium-polymer battery matches the original 11.4V 48Wh 4200mAh specification. It replaces part numbers including L17L6P71, SB10K97617 and 01AV470. Buyers must verify the original battery part number before ordering.

Runs cool with no added noise

The cell operates at the same voltage and capacity as the factory pack, so thermal output and power draw remain unchanged. CE, RoHS and FCC certification confirm compliance with safety and environmental standards. No moving parts mean silent operation.

Fits the existing battery bay exactly

The connector layout matches the pictures supplied, allowing a straight swap without adapters or cable routing. The pack frees the notebook from a degraded or failed original cell. It is not suited for models outside the X280 and A285 series or for users needing a higher-capacity option.

Questions about this item

How do I install the L17L6P71 battery in my ThinkPad X280, and what step do people often miss?

Open the back case, disconnect the old battery connector, fit the new 11.4V 48Wh pack, and reconnect — the step many skip is verifying the part number on the original battery before ordering.

What maintenance or replacement will the L17L6P71 need later?

As a lithium polymer pack rated at 4200mAh, it will eventually hold less charge; plan to replace it once runtime drops below your needs, typically after several hundred full cycles.

What limit appears first under sustained use of the L17L6P71?

The 48Wh capacity sets the runtime ceiling; under continuous load the battery will deplete to empty before any thermal or voltage threshold is reached.
