Lenovo 5B11B36283 Replacement Battery Review

Lenovo 5B11B36283 replacement battery, an 11.1V 45Wh three-cell FRU for the IdeaPad 3 15IAU7 (chassis 82RK/82T7).

Lenovo's FRU numbering scheme is a genuine service part code, one tier more reliable than a retailer-only listing.

What to check before you buy

Confirm the 82RK or 82T7 chassis suffix on your IdeaPad 3 before ordering, since the series name spans several distinct internal boards.
