A battery cell, a battery, an energy storage apparatus, and an electrical apparatus. The battery cell comprises a housing and a pressure relief member. The housing has a first wall, and the first wall has a first side surface facing the interior of the battery cell. The pressure relief member is disposed on the first wall. The pressure relief member has a weak structure. The pressure relief member is configured to relieve the internal pressure of the battery cell. In the thickness direction of the first wall, the weak structure does not go beyond the first side surface in a direction toward the interior of the battery cell.
