Ready for ThinkPad T470 and T570

This 6-cell lithium-ion battery delivers 72 Wh at 11.3 V DC and 6600 mAh. It is built as a direct replacement for the original pack in compatible notebooks. The proprietary form factor matches the factory design exactly.

Proprietary pack fits without modification

The battery uses a custom shape that slides into the standard bay on the listed models. No adapter brackets or cable changes are required during installation. Rechargeable chemistry supports normal charge cycles through the notebook's own controller.

Capacity fixed at 72 Wh — no expansion possible

Runtime is limited to the rated watt-hour figure and cannot be increased without a larger physical pack. The proprietary size prevents the use of higher-capacity aftermarket cells. Users needing longer unplugged time must carry a spare unit or an external power bank.
