Fig. 3－2 The Voltage Setting Curve Vs. Ambient Temperature
If the voltage lower than 2.225 or higher than 2.35 after temperature correction, the suggesting
adopted can be charging by 2.25V or 2.35V directly without using temperature compensation.

3.2 Ambient temperature vs. Battery Life
The high temperature will damage the battery, reduce the battery life. When
temperature exceeds 25℃, the battery life will decrease half per 10℃ temperature
raise. For example, the design life of battery is 20 years at 25℃, if the battery is
