Batteries aren't cheap enough to use as a the sole storage modality, because they suck for very long term storage. Their cost per unit of energy storage capacity is not amortized over enough charge/discharge cycles. The answer to that is use a different (typically less efficient) way to store energy in that case. Cost savings can be dramatic at scale. The strawman argument that storage isn't feasible because batteries by themselves don't cut it is regularly seen from nuclear bros. Even MIT came out with a study doing this, a study that very carefully avoided the word "hydrogen".
