A.5 Thermal derating
The current rating of the PL must be reduced
at high ambient temperatures or the display
will darken until it is unreadable. The currents
indicate what can be done at the same time.
Because the limit is due to heating, there are
many combinations of charge and load current
which will produce the same heat level. This
table shows the limits of some combinations.
