Lenovo 5B10X02602 Replacement Battery Review
Lenovo 5B10X02602 replacement battery, the 3-cell 11.1V 45Wh battery for the IdeaPad 3 15ITL05 (81X8), interchangeable with FRUs 5B10X02599 and 5B10X02607.
This is the larger of the two batteries Lenovo fitted to the IdeaPad 3 15ITL05, and the one on models that support Rapid Charge. Lenovo also lists this FRU for several other IdeaPad 3 machine types.
What to check before you buy
Models with this 45Wh battery have no 2.5-inch drive bay; models with the 35Wh 2-cell battery (L16C2PB1 family) do. The two batteries are not interchangeable, so match the one you have.
