Compatible ThinkPad models

This replacement battery fits Lenovo ThinkPad A485, P51s, P52s, T470, T480, T570 and T580 systems. It is built for professionals who need dependable power during office work or mobile tasks. The 24 Wh lithium-polymer pack restores original runtime for supported business notebooks.

Installation and common issues

The battery slides into the internal compartment after removing the bottom case screws and disconnecting the old pack. Most installations finish in minutes with a small Phillips driver. A frequent issue is forgetting to detach the internal connector before fitting the new unit, which can prevent the system from recognising the replacement.

Li-polymer capacity limits

The 11.4 V, 2100 mAh chemistry delivers 24 Wh of energy, which defines the maximum runtime per charge. Capacity will gradually decline with repeated cycles and cannot be increased without a physically larger pack. The built-in protection circuit stops charging at the cell voltage limit, so the battery will not accept more energy than its rated capacity.
