PURPOSE:To expand cycle life in a heavy discharge use, by forming a lead alloy grid of a maintenance-free lead battery, adding a specific quantity of antimony, selenium, arsenic, tin and cadmium. CONSTITUTION:An alloy of antimony 0.8-3.0wt%, selenium 0.005-0.1wt%, arsenic 0.025-0.3wt%, tin less than 0.2wt%, cadmium 0.01-0.5wt%, and lead of remaining percent is used to form a lead alloy grid of a maintenance-free lead battery for automobile etc. Therefore, cracking is controlled by adding an adequate content of selenium, age-heating is accelerated by adding an adequate content of arsenic, molding effect is improved by adding an adequate contents of antimony and tin, and so on, and deterioration of cycle life in a heavy discharge use can be reduced. |
