How to Evaluate Time-Adjusted Battery Capacity Results
Manufacturers provide a reference temperature at which the battery will perform to specification, generally 25°C or 20°C. Temperatures higher than the reference value reduce the life of the battery. During a performance test, higher temperatures will cause an easier and quicker release of energy resulting in an apparent higher

Battery Temperature Compensation
The temperature compensation value is from 25°C, so 40°C-25°C = 15°C x -0.06V/°C = -0.9V + 28.6V = 27.7V. So the battery charge voltage at 40°C would be 27.7V. Example 2: let''s use a 12V system, with a charge voltage of 14.1V, a temperature compensation value of -3mV/°C/cell, and a battery temperature of 5°C.

Lithium-Ion Batteries: Safe Temperatures?
Safe storage temperatures range from 32℉ (0℃) to 104℉ (40℃). Meanwhile, safe charging temperatures are similar but slightly different, ranging from 32℉ (0℃) to 113℉ (45℃). While those are safe ambient air temperatures, the internal temperature of a lithium-ion battery is safe at ranges from -4℉ (-20℃) to 140℉ (60℃).
