The lead market's reliance on secondary (recycled) sources makes it structurally different from other base metals. Smelters that process scrap lead-acid batteries account for 62% of global refined lead output. This recycling loop insulates the market from the mining disruptions that affect copper, zinc, and nickel.
The summer battery replacement cycle is underway in the US and Europe. Replacement battery sales at major auto parts retailers typically rise 8-12% between June and August as warmer temperatures stress older batteries in vehicles. Start-stop vehicles, which carry heavier electrical loads, have a shorter battery replacement cycle, supporting demand.
In China, the electric bicycle (e-bike) market continues to drive lead-acid battery demand. E-bike sales rose 6% year-on-year in May, with replacement battery demand following the same pattern. Lead-acid remains the dominant e-bike battery chemistry due to cost advantages over lithium-ion in the low-cost segment.
The ILZSG forecasts a 25,000t refined lead surplus for 2026, down from 35,000t in 2025. The narrowing surplus reflects steady demand growth and constrained primary mine supply. However, the surplus, combined with LME stocks above 300,000t, suggests ample availability.
Lead is the most forgiving metal for procurement teams right now. Abundant stocks and a flat forward curve mean there is no urgency to extend coverage. Battery manufacturers should focus on collecting and selling scrap at favorable spreads, particularly in the current seasonal demand uptick for replacement batteries.
