Abstract :
To optimize the endurance of VRLA-batteries under float charge the charging voltage is a very important parameter. The charging voltage at different temperatures must be fixed to the value at which the following conditions are fulfilled: a high state of charge of battery electrodes, even at the end of design life; low gassing rate and waterless; high recombination rate without thermal-run-away; small varieties between the single cells in strings; and low corrosion of positive electrode and negative top lead. In this paper the influence of two a.m. variables, temperature and charging voltage, on the endurance was investigated. An endurance test of four different designs of dryfit-batteries in Gel-technology, and measurements of polarization at different temperatures, are described
