When your ThinkPad T490s needs a fresh power source, this 2-Power main battery pack steps in with a no-compromise approach: it's built to match the original battery's fit and electrical behaviour, so you can swap it in and keep working without second-guessing charge levels or shutdown behaviour.

In daily use

Install the pack into the T490s bay and the system recognises it immediately, showing accurate remaining runtime in Windows or Linux.

The Li-Ion cells hold their charge well during standby, so the notebook is ready when you are — whether you're in back-to-back meetings, travelling, or working from a café. The pack charges through the ThinkPad's standard USB-C or slim-tip adapter, depending on your model, and reaches full capacity in about the same time as the original battery.
