Quantum batteries (QBs) have emerged as promising candidates capable of outperforming classical counterparts by utilizing entangled operators. Spin chains, in particular, exhibit unique {charging} properties across diverse settings. Here, we introduce the kicked-Ising model as a QB and analytically characterize its charging dynamics within the self-dual operator regime, valid for arbitrary system sizes and Floquet cycles. Using Clifford quantum cellular automata and momentum-space Floquet analysis with the Cayley-Hamilton theorem, we obtain exact expressions for energy injection, uncovering the influence of boundary conditions and spin-chain parity on charging performance. The kicked-Ising QB achieves maximal charging while exhibiting remarkable robustness against disorder. We further propose an intensified protocol within a fixed time window that enables faster and more efficient energy injection, while non-uniform kick schedules enhance experimental flexibility. Spin correlators analysis further shows that low-frequency driving boosts energy injection, highlighting a clear connection between charging, scrambling, and kick-induced delocalization. Our theoretical framework are supported by tensor-network simulations and finally verified on IBM quantum hardware. Accounting for platform-specific constraints, we demonstrate that the kicked-Ising QB offers a scalable, disorder-resilient protocol and testbed to assess quantum platforms.
