【SMM Analysis】 Why Are Chinese Lead-Acid Battery Enterprises Taking More Holidays for the 2026 Labor Day? As the Labor Day holiday approaches at the end of April, SMM conducted a survey on holiday arrangements among lead-acid battery enterprises across 10 provinces in China.

In April 2026, China's secondary lead production showed a pattern of MoM rebound and YoY decline. Monthly secondary lead production was up 12.72% MoM and down 24.61% YoY; secondary refined lead production was up 8.7% MoM and down 33.14% YoY significantly.

Recently, CATL announced that Zinfra, an Australian energy infrastructure service provider, has officially signed a Memorandum of Understanding (MoU) with CATL, establishing a strategic cooperation framework. The two parties will jointly deliver and operate large-scale Battery Energy Storage System (BESS) projects in Australia, accelerating CATL's localized presence in the Australian market Zinfra is a leading energy and utility infrastructure service provider in Australia, specializing in engineering, project management, and operations & maintenance (O&M) in the power and gas sectors. With an annual project and service portfolio exceeding AUD 1.2 billion, Zinfra has extensive experience in the construction and maintenance of power and gas networks, as well as the delivery of renewable energy assets. This partnership marks an important step for CATL in demonstrating its integrated "product + service" capabilities in overseas markets. By leveraging Zinfra's local project channels and engineering delivery capabilities, CATL aims to strengthen the local O&M and service capabilities required for overseas energy storage projects, adopting a light-asset, low-risk model. To date, CATL has ranked first globally in energy storage battery shipments for five consecutive years. According to relevant data, CATL's global market share in energy storage battery shipments reached 30.4% in 2025, with approximately 2,300 cumulative projects worldwide. Looking ahead, CATL will continue to collaborate with local partners such as Zinfra, applying its advanced energy storage battery technology to empower Australia's energy transition and help build a more resilient and sustainable energy infrastructure.

SMM April 30: SHFE lead fluctuated this week, with prices pulling back slightly near the weekend. On the raw material side, scrap battery procurement prices were largely stable overall, with only a few smelters in east China and north China making slight reductions early in the week. Current scrap battery retirement volumes remain at low levels, with tight supply for both recyclers and smelters. Smelter arrivals declined significantly WoW this week, with raw material inventory maintained at low levels of only 1-2 weeks. Combined with recyclers generally taking 2-6 days off for the Labour Day holiday, short-term supply circulation is expected to be further constrained. Looking ahead to next week, smelter procurement prices are expected to remain largely stable: upward adjustments are constrained by finished lead profit pressure, while downward adjustments are supported by low raw material inventory, leaving limited room for fluctuations in either direction.

SMM April 30 update: Lead prices fluctuated at highs before pulling back this week, with secondary refined lead generally trading at discounts. Early in the week, smelter maintenance increased and regional supply tightened, with quotes maintained at a discount of 80 yuan/mt to a premium of 50 yuan/mt. Downstream buyers saw weak rigid demand ahead of the holiday, and market trading was sluggish. From mid-week to the weekend, lead prices weakened. Raw material cost support narrowed quotes to a discount of 50 yuan/mt to a premium of 50 yuan/mt, as downstream enterprises gradually went on holiday and spot cargo transactions remained weak. Regional secondary lead supply contracted as smelters held prices firm on shipments. Combined with stable scrap battery procurement prices, smelting costs pulled back somewhat, and losses were slightly repaired. As of April 30, large enterprises posted losses of 109 yuan/mt, while small and medium-sized enterprises posted losses of 309 yuan/mt. Next week, scrap battery raw material inventory will remain tight, some smelters will cut production, and secondary lead supply will contract. Downstream consumption will remain weak, the weak supply-demand pattern on both sides will continue, and industry losses will be difficult to improve. Secondary refined lead is expected to maintain a discount of 50-0 yuan/mt.
