It was learned that the SMM weekly composite operating rate of lead-acid battery enterprises in five provinces was 73.92% from March 13 to March 19, 2026, up 0.46 percentage points WoW from the previous week. Recently, production at lead-acid battery enterprises remained relatively stable. Apart from slight production adjustments at a small number of enterprises, changes in production at other enterprises were relatively small. Over the past two years, as AI development accelerated, battery demand from data centers improved. In particular, lead-acid battery enterprises that secured tender orders had full order books, with production lines operating at full capacity. In addition, for civilian battery products, end-use consumption in the e-bike and automotive battery markets showed mediocre performance. Considering that from April to May is the traditional consumption off-season, some enterprises with average order intake only maintained operating rates at 70-80%, and needed to adjust production based on subsequent order conditions.
