71Wh Li-ion Battery for Lenovo Yoga 7

This 15.36V lithium-ion pack replaces the original L21M4PE3 cell in Lenovo Yoga 7 16IAP7, 14IAL7 and 14ARB7 2-in-1 laptops. It restores factory runtime for mobile professionals who need reliable all-day power.

Four-Cell 15.36V Design Limits

The four-cell 71Wh layout delivers 4623mAh at a fixed 15.36V, so it fits only the listed Yoga 7 type numbers 82QG, 82QE, 82QF and 82VD. It will not operate in models that require a different voltage or cell count.

Match Your Exact Type Number

Verify the type number printed under the back cover — 82QG, 82QE, 82QF or 82VD — before ordering. A mismatched type number means the battery will not be recognised by the system.
