Constant Charging Voltage
Shown is the constant charging voltage in relation to the ambient temperature. The bandwidth
shows a tolerance of ± 30mV/cell. This constant voltage is suitable for continuous charging and
cyclic operation. In a parallel stand-by mode it always keeps the battery in a fully charged state;
in a cyclic mode, it provides for rapid recharging and high cyclic performance.

Capacity vs Operating Temperatures
Shown are the changes in capacity for wider ambient temperature range, giving the available
capacity, as a percentage of the rated capacity, at different ambient temperatures, for 3 different
load examples, with uninterrupted discharge to the appropriate discharge cut-off voltage. The
values for the upper edge of the curve were obtained from charging at an ambient temperature of
±20ºC with a voltage limit of 2.4V/cell. For the lower edge, charging was carried out at the specified
ambient temperature. The curves show the behavior of the battery after a number of cycles.
