The temperature rating for the device 

(-4°F to 158°F, or -20°C to 70°C) 

may exceed the usable range of some 

batteries. Alkaline batteries can rupture 

at high temperatures.

Alkaline batteries lose a significant 

amount of their capacity as temperature 

decreases. Therefore, use lithium 

batteries when operating the device in 

below-freezing conditions.
The device operates on two AA 

batteries. 

You can use alkaline, NiMH, or 

lithium batteries. Use NiMH or lithium 

batteries for best results.
