KL … P Battery Range: This GAZ® cell type has been especially designed for low rates of discharge over long periods, i.e. the current is relatively low in comparison with the total stored energy. The discharges can generally be infrequent and the recommended discharge time for the KL … P range is 1 hour to 100 hours.
Important Notice: The nominal capacity C5 is not the basis for the performance of the batteries. Performance depends on the battery construction or on the different battery ranges, respectively. Therefore, our discharge tables should be used to find out the appropriated cell type for a specific application. The nominal capacity C5 of KL … P range batteries is
based on the available ampere hours (Ah) at a discharge rate of 5 hours to a final discharge voltage of 1.00 V per cell at 20 °C ± 5 °C. Nominal voltage per cell is 1.2 V. Discharging conditions The discharge performances as well as the nominal capacities C5 given in this brochure are only valid for fully charged cells in accordance with IEC 60623 und EN 60623, point 4.1.
