At the Multi Commodity Exchange, lead for delivery in August fell by 45 paise, or 0.30 per cent to Rs 149.05 per kg in business turnover of 1,615 lots.
Similarly, the metal for delivery in September contracts was trading lower by 30 paise, or 0.20 per cent to Rs 150.25 per kg in 85 lots.
Analysts said the weakness in lead futures was mostly due to a sluggish demand from battery-makers at the domestic markets.
