The temperature rating for the GPS 72 may exceed the usable range of some batteries. Alkaline batteries can rupture at high temperatures.

Alkaline batteries lose a signiﬁ cant amount of their capacity as temperature decreases. Use lithium batteries when operating the GPS 72 in below-
freezing conditions. Extensive use of screen backlighting will signiﬁ cantly reduce battery life.
