Replacement battery for Lenovo E41 E42 K42

This 11.1 V 4400 mAh lithium-ion cell replaces original Lenovo packs such as BATFT10L61 and BATEL80L6. It fits Lenovo E41, E42, E42G, E42L and K42 models as well as Dell Inspiron 1425, 1427 and 1428 notebooks. The black housing matches the OEM finish and the unit ships new and unused.

Steady output through a full work session

The 4.4 Ah capacity delivers consistent voltage across the discharge curve rather than a brief peak. Lithium-ion chemistry maintains stable current during extended typing, browsing or video playback without the sharp drop-off seen in aged cells. Capacity remains reliable over repeated charge cycles when the pack is kept cool.

Direct swap with no soldering required

The pack slides into the battery bay and locks with the original latches; no tools or cable modifications are needed. Alignment tabs on the 190.00 x 45.00 x 20.00 mm case prevent forced insertion. The only common issue is forgetting to charge the new cell fully before first use, which can trigger a false low-battery warning.
