STORAGE, SELF DISCHARGE and SHELF LIFE

Temperature Characteristics
At higher temperatures, the electrical (Ah) capacity of a
battery increases and conversely at lower temperatures,
the electrical (Ah) capacity of a battery decreases.
Figure 4 shows the effects of different temperatures in
relation to battery capacity.
Self Discharge
The self discharge rate of NP batteries is approximately
3% per month when stored at an ambient temperature of
20°C. The self discharge rate will vary as a function of
ambient storage temperature. Figure 5 shows the
relationship between storage times at various
temperatures and the remaining capacity.
