Pauli noise, represented by Pauli operators (X, Y, Z), is a common type of interference in quantum batteries, leading to the flipping of quantum states. This noise can significantly influence the charging and discharging processes of a quantum battery, thereby affecting its capacity. In this paper, we investigate quantum batteries composed of bipartite quantum systems, focusing on how local Pauli noise affects battery capacity. Specifically, we examine two-qubit Bell-diagonal states and X-type states to characterize the trend in the maximum capacity of the quantum battery across the entire system. Additionally, we provide the minimum value of the maximum extractable work under the influence of local Pauli noise.
