The supplier notes the battery fits only IdeaPad Slim models, not IdeaPad Pro variants. Opening the back cover to compare the installed battery with the product photo avoids mismatched parts.

Questions about this item

Does the L23B4PK3 battery pack include any tools or adhesive strips for installation?

The box contains the 15.08 V 76 Wh 5040 mAh 4-cell Li-ion battery only; tools and adhesive are not included.

My IdeaPad Slim 5-16IRU9 (83FW) also lists 47 Wh and 57 Wh options — why choose the 76 Wh L23B4PK3?

The 76 Wh capacity gives the longest run-time of the three sizes; verify the physical shape matches the photo before ordering.

What does the 15.08 V rating mean once the battery is fitted in the laptop?

It matches the original 15.08 V system voltage so the laptop charges and reports capacity correctly.
