Voltage temperature factor

Voltage temperature factor 1 indicates over charge detection voltage, over charge release voltage, over

discharge detection voltage, and over discharge release voltage.

Voltage temperature factor 2 indicates over current detection voltage.

The Voltage temperature factors 1 and 2 are expressed by the oblique line parts in Figure 4.
