3.7V~Wide Temperature Range Series

This series of products are mainly applicable to various wireless portable electronic products or equipment used in wide temperature range (i.e. large temperature difference) environment, such as car recorder, tire pressure monitor, heating/cooling/temperature regulating instruments, cold injection molding products, outdoor work/expedition/duty/driving equipment, solar lighting, GPS, outdoor testing instruments, etc.

Most of the batteries in this series are compatible with the corresponding models of ordinary digital/high-temperature/low-temperature batteries, and the performance is more stable in room temperature environment.
