In mobile use, the battery decided laptop life, because laptop use a lithium-ion battery, in the non-normal temperatures, too high or too low will bring a variety of problems, then what the temperature affect the Laptop battery?
A. 0-40 ℃ is the most reasonable working environment
Notebooks in use, humidity, static electricity, temperature, and so have an impact on it, but the lithium-ion BATCL50L battery is most sensitive to temperature, high or low temperatures, the battery will bring negative impact to varying degrees, usually, lithium-ion battery limit ambient temperature -20 ℃ ~ 60 ℃, while the 0 ℃ ~ 40 ℃ was the most reasonable working environment, but to play a laptop battery performance potential, 20 ℃ or so is the best use of the environment.
B. -25 ℃ below will affect the battery life
Although the laptop battery to allow the use of -20 ℃ environment, but this would be the battery charge and discharge performance impact is very large, usually, the lower the ambient temperature, the battery inside the lower the activity of active material, electrolyte resistance and viscosity of The higher the ion diffusion more difficult, the battery charge and discharge is not easy.
For example, when the ambient temperature is below zero, the battery charge-discharge efficiency will be greatly reduced, thereby charging rate will be very slow, full of electric power after the time that only about 60% of the original, when the ambient temperature falls below the minimum temperature limit (for example, — 25 ℃), the battery electrode reaction rate is very low, the electrolyte may even consider freezing point, the battery performance may be only 10 percent, seriously affecting battery life.
C. 60 ℃ and above may explode
With the low-temperature case, if the laptop battery life in high-temperature environment, the same will affect the battery charge and discharge efficiency, but also more serious damage to the battery, such as the use of poor quality, or charger charging time is too long to make the battery heat large, when the charge temperature exceeds the maximum limit temperature, which will destroy the chemical balance within the battery, resulting in performance degradation of A1045 battery materials, battery life reduced.
By the same token, the battery during discharge time, that is, when we use the notebook, due to internal short-circuit the battery or battery design flaws, if the temperature exceeds the maximum limits, the drop in battery-powered, life receded, will be bring serious explosion, burning and other accidents.
