We measured the discharge characteristics of the battery
when it was recharged to capacity. The battery was
connected to an electronic load in the 1[A] constantcurrent
load mode. Just as done in the recharge characteristics
measuring, we compared the discharge characteristics
at room temperature with those at low temperature.
Figure 8 charts the results therefrom. It was found that
the discharge efficiency at low temperature is far lower
than that at room temperature.
