Direct Replacement Battery

The NShi L20D3P71 is a new 11.52V 57Wh lithium polymer battery built to replace the original power cell in compatible Lenovo ThinkPad models. It targets owners of T590, T15 first and second generation, P53S, and P15S first and second generation machines who need a like-for-like swap.

Plug-and-Play Installation

The unit fits into the existing battery bay without adapter cables or firmware updates, freeing the user from sourcing separate connectors or modifying the chassis. Verification of the original part number on the old battery is required before fitting to ensure the connector keying matches the replacement.
