Replacement 10.8V 57Wh 6-cell battery for compatible Lenovo ThinkPad and Edge laptops

  • Battery Capacity5200mAh
  • Reliable power with 10.8V 57Wh capacity
  • Extended runtime from 5200mAh 6-cell design
  • Broad compatibility across ThinkPad T, W, L, SL and Edge series
  • Direct replacement for multiple Lenovo part numbers

Replacement Battery for ThinkPad L-Series

This new aftermarket battery replaces original Lenovo part numbers across the ThinkPad L421, L520, SL410, SL510, T410, T420, T430, T510, T520, W510 and W520 families as well as Edge E420, E425, E520 and E525 machines. It delivers a 10.8V 57Wh 5200mAh rating in a six-cell pack built to match the form factor of the factory unit.

Verify the Original Part Number Before Ordering

Check the label on your existing battery for one of the listed part numbers such as 42T4751, 42T4753, 42T4755, 42T4757, 42T4791, 42T4793, 42T4795, 42T4797, 42T4848, 42T4852, 42T4911, 42T4921, 42T4923, 42T4925, 42T4927, 45N1001, 45N1003 or 45N1005. Confirm that your laptop model appears in the compatible list because several similarly named ThinkPad generations use different battery shapes and connectors.

Steady Output Across a Full Work Session

The 57Wh capacity is rated for sustained discharge rather than a brief peak, so the voltage remains stable while you work through a typical business day. The six-cell layout spreads the load evenly, reducing heat buildup during long periods of unplugged use and helping the pack hold its rated capacity over many charge cycles.
