[CAIEPO-Lenovo-45N1005(70+)-57Wh-3]

Everything went fantastically from ordering to delivery. Thank you and always happy!

The new battery gave the laptop a life back beyond the charging cable, at a low price. Over 4 hours of running time, with intensive use. Top.

Great quality, like original.

Same battery, let's see how it does. Fast delivery, everything so far
