Lenovo 5B11B48825 Replacement Battery Review
Lenovo 5B11B48825 replacement battery, the 4-cell 15.36V 80Wh battery for the Legion 5 15ACH6H (82JU), also listed by Lenovo for the Legion 5 15ACH6 and 15ITH6.
The larger of the two batteries Lenovo offered on the 2021 Legion 5 15-inch. Lenovo treats 5B11B48824, 5B11B48825, 5B11B48829 and 5B11B48830 as interchangeable service parts. Lenovo does not list it for the 17-inch Legion 5 models.
What to check before you buy
The Legion 5 15ACH6H shipped with either this 80Wh battery or a 60Wh battery (5B11B48816 family). Check the Wh rating on your old battery label before ordering.
