CLOSEDDTYPE LEAD BATTERY

摘要

PURPOSE:To scheme to improve the low-temperature high-rate discharge characteristic of retainer-type battery by increasing the degree of oppression of a separator against the electrode plate in battery fabrication. CONSTITUTION:In fabrication of a retainer-type battery in which the amount of electrolyte per 1 gram of positive electrode active agent is retained below 1.2ml, the degree of oppression of separator against the electrode plate in fabrication is set at 20kg or more per 1dm<2>. Thus, the efficiency of closed reaction and low-temperature high-rate discharge characteristic can be improved.
