alert@ (Adds Shanghai closing prices, analyst's comments and China data) BEIJING, Dec 25 (Reuters) - Lead futures in China closed up 2.15% on Wednesday, after marking their biggest percentage gain in 5 months earlier in the session, buoyed by expectations that restocking of the battery-material would continue through January. "Domestic lead prices were driven by restocking expectations and amid the heavy pollution alert in Henan province," Jinrui Futures analysts wrote in a note on Wednesday. "There's still downstream restocking expectation at this year end, which may extend to early January," the note in Mandarin said. China's central province of Henan, home to several lead smelters, issued a heavy pollution alert last week under which industrial plants need to cut production and road transport. Copper futures in China rose on Wednesday after a Sino-U.S. trade deal removed some worries about the global economy's health, but trading was thin as many investors stayed on the sidelines due to Christmas holidays. "Market still holds relatively big expectations from domestic stabilization policies, and the Phase 1 trade deal with the United States also is good news ... copper prices might maintain a relatively strong trend," Huatai Futures analysts wrote in a note to clients. A meeting to discuss the treatment and refining charges for the first quarter next year is scheduled to be held on Thursday. The charges are paid by copper miners to smelters to process ore into refined metal.
