Genuine Lenovo 57 Wh notebook battery
This 57 Wh lithium-ion pack is built for Lenovo ThinkPad notebooks. It replaces the original cell when runtime has fallen off. Six cells deliver the rated capacity in a proprietary form factor. The unit is new and ready to install.
Slim proprietary pack with six cells
The battery measures 8.2 inches wide, 2.2 inches deep and 0.8 inches high at roughly 12 ounces. Its slim profile fits the internal bay without adapters or cable routing. Rechargeable lithium-ion chemistry supports daily charge cycles. The shape matches the factory footprint exactly.
Direct replacement for ThinkPad L412 L512 T410
Swapping the old pack restores full mobile runtime for these models. The jump is worth it when the current battery no longer holds a useful charge. No firmware update or hardware change is required. Compatibility is limited to the listed series.

Questions about this item
What proprietary interface does the 57 Wh battery use to connect to ThinkPad models?
The battery mates directly with the ThinkPad's internal battery bay through a model-specific connector built into the 8.2" by 2.2" pack; no separate cable or adapter is required.
Will the 0.8" high pack fit my ThinkPad T410 without modifying the chassis?
Yes — the 0.8" height, 8.2" width and 2.2" depth match the factory battery compartment on T410, T510, W510, L412 and L512 models, so the lid closes normally.
Which step do owners often skip when installing the 6-cell unit?
After sliding the pack in until the latches click, many forget to run a full charge cycle in the OS power manager so the firmware learns the new 57 Wh capacity.
